Pressure Systems offers an extensive array of hardware to facilitate the installation of KPSI Transducers into almost any application. Contact our Technical Support staff for assistance in selecting the hardware that may best suit your application or if you have unique requirements that may require a custom solution.

Anti-Snag Cone Anti-Snag Cones are designed to fit over the cable end of either 1.0" or 0.75" diameter transducers to prevent the transducers from getting hung on obstacles when pulling the cable. The cones are constructed of PVC and come in separate sizes for the two diameters.
Cable Hanger The Cable Hanger is used to suspend the transducers in the liquid media. The hanger slides onto the cable from the unterminated end and is easily positioned while pushing the ends of the hanger together. As the hanger expands from the weight of the transducer, it grips the cable by the sheath. The cable hanger is 6.0 in (15.3 cm) long and is constructed of 304 stainless steel. The cable hanger is not recommended for cable lengths in excess of 500 ft (150 m) as it does not take advantage of the Kevlar® strength members in the cable.
Mounting Clamp The Mounting Clamp is used to secure 1.0" diameter transducers to a bulkhead. The clamp is consists of a 304 stainless steel bracket with a thermoplastic insert that holds the transducer housing.
Well Caps Locking Well Caps enable transducers to be suspended within the well while providing security. The vented orange PVC caps are 2" or 4" ID and come with a 304 stainless steel dock (ring and threaded quick-link) to support a cable hanger. The dual-hinge locking lid uses a Buna-N/Nitril o-ring for a watertight seal. The black triangle warning label on the lid can be marked for well identification.
Junction Box The Junction Box provides a water-resistant enclosure for electrically connecting the transducer cable to the users system via a terminal strip. The enclosure also provides convenient location for terminating the vent tube on vented gage transducers. The enclosure can be ordered with either a vent filter or an aneroid bellows. The enclosure is constructed of polycarbonate with a clear top incorporating a neoprene seal. The junction box is rated IP66 and measures 9.45" L x 6.30" W x 4.72" H. Mounting screws are provided.
Identification Tags Identification Tags are available to attach to the transducer cable to provide easy identification in the field. User-specified information is laser engraved onto the 1.0" square tag, which is constructed of 304 stainless steel.
Cable Splice Kit The Cable Splice Kit provides a waterproof connection to extend or repair Pressure Systems submersible cables. In many cases, the cable splice kit is a more economical alternative for repairing damaged cable. The kit includes all necessary items to electrically connect and insulate the conductors, couple the vent tubes, and seal the 316 stainless steel housing to either polyurethane and ETFE cable. Assembly instructions are also included.

Pressure Systems offers two types of Display Meters to provide a visual readout of a single KPSI transducer having mA or VDC output. Both varieties utilize a red 0.54" LED display with 4 active characters to indicate a numeric range of -1999 to 9999. The units operate from VAC power and provide a 24 VDC supply for power to the transducer.

The Model 3019 Digital Readouts provide a sophisticated display of the transducer output with six 14-segment LED's for display of true alphanumeric characters; the last two used for process descriptors. These readouts offer programmable input configuration, isolated transducer power supply, selectable 2-point scaling or up to 17-point linearization, optional 4-20 mA retransmission, and two or four optional 10-amp SPDT alarm contacts for control.

Standard lead times for many of Pressure Systems line of KPSI Level and Pressure Transducers are 5 working days. At a premium, PSI offers an Expedite Shipment Service in order to ship transducers within 1-4 working days. This service includes requirements for custom pressure ranges within the limits of the relevant transducer models as well as custom cable lengths. Expedite shipment service is available on most models. Consult our Customer Service staff for availability.

KPSI Transducers are available in three different Reference Pressure Formats to meet varying requirements. The format indicates whether the sensor is referenced to atmospheric pressure (vented gage), a hard vacuum (absolute), or a simulated atmospheric pressure (sealed gage).

Vented gage reference is usually used in lower full-scale range transducers where the sensor must track changes in atmosphere to maintain stated accuracy. Care must be taken to employ appropriate moisture protection to prevent humidity from entering the transducer via the vent tube.

Sealed gage and absolute reference is typically used when the full-scale range is above 700 ft (210 m) H₂O. Changes in atmospheric pressure have negligible impact on the accuracy of transducers at that range and moisture protection is not a concern since no vent tube is required. Sealed gage units are absolute units that are electrically adjusted to simulate reference to the atmospheric pressure at site of the installation. Base elevation with respect to sea level of the site must therefore be specified when ordering sealed gage transducers. Consult our Technical Support staff if you need assistance in choosing the reference pressure format.

A variety of electrical Transducer Output signals are available to facilitate interfacing to almost any system. The most popular output signal is 4-20 mA, which is transmitted over two wires along with power for the transducer. Transducers with this output are typically referred to as transmitters and interface with almost any data logger or PLC.

Amplified voltage output is also commonplace requiring three wires for power and output signal. Most common is 0-5 VDC, but the full-scale voltage output can be factory-adjusted to as much as 2.5 VDC less than the anticipated excitation voltage supply. Specify the voltage range required when ordering VDC output transducers.

Two basic Electrical Connection options are offered to facilitate submerged use in different environments.

The standard connection is a submersible cable exit using a factory molded polyurethane seal to the transducer housing. This provides the best water ingress protection. As an option, a compressed gland seal is offered to facilitate field attachment but requires considerable care in assembly to insure water-proof integrity.

An optional ½”-14 male NPT conduit fitting can also be specified for a more rugged and protected connection. This configuration also employs the standard molded cable seal or the optional gland cable seal.

As an option, a precision silicon temperature sensor can be installed within the transducer to provide a separate 4-20 mA temperature measurement output over the range of -20 to 60ºC. The accuracy of the temperature measurement is ±4ºC.

Optional Wetted Materials are offered for both the transducer and the cable to enable compatibility with a wide range of liquid media.

Transducer Housing Assemblies
The transducer assemblies are most commonly made from 316 stainless steel, which offers good compatibility for most water and hydrocarbon liquid applications. Alternatively, the transducer assembly can be made from titanium, which offers superior compatibility to salt water and chemical liquid applications.

Cable Seals
The molded cable seal is KPSI’s standard offering and provides a very reliable injection molded polyurethane seal. The gland cable seal is primarily used for ETFE cable and incorporates a compressed Viton® gland.

Transducer Cable
The jacket on our transducer cable is typically constructed from polyurethane, which provides excellent general-purpose use and reliability with good flexibility and economy. For liquid media such as hydrocarbons and other chemicals, ETFE can be specified providing excellent compatibility and maintaining all the features of the polyurethane though somewhat less flexible and more expensive.

Consult our Technical Support staff for the material best suited for the anticipated media.

Lightning Protection is designed to protect KPSI Level and Pressure Transducers from damaging surge voltage and current. The protection is offered for 2-wire 4-20 mA output as well as 3-wire VDC and digital output configurations. This circuit is capable of protecting against fast rising voltage transients as well as current surges associated with lightning discharges. The protectors are a multi-stage design, with a solid-state section that intercepts the leading edge of the surge within nanoseconds. The second stage of the design contains a gas discharge tube which crowbars up to 20,000 ampere currents to ground. The tube remains in the crowbar state until the surge has passed, then automatically resets the line to normal operation without the need to reset a circuit breaker. Each circuit consists of two parts. One  is  housed  integral  to the  transducer via a factory-installed extension to the end of the housing while the other is installed by the user between the transducer wiring and the system. External line protection must be used at all times to ensure lifetime warranty coverage. The protectors are FM/UL/CUL Intrinsic Safety rated for use in hazardous environments when used with an appropriate Intrinsic Safety barrier. The transducer carries a lifetime warranty for damage due to lightning or voltage spikes when this 2-part option is properly installed.  It is not warranted against continuous over voltage. This option is not available for the Series 300DS.

Note: For 4-20 mA output transducers the supply voltage must be at least 15 VDC when Lightning Protection is installed. Lightning Protection is available as an option on all new units.

Pressure Systems offers removable, watertight devices known as well caps to fit 2" and 4"" well casings.  A well is described as any excavation that is drilled, bored, or dug with the intended use being for the location, monitoring, dewatering, or acquisition of ground water, or for conducting pumping or aquifer tests. 

These well caps will typically be used in conjunction with the KPSI series 550 waterMONITOR submersible datalogger.  The 550 is designed for submergence in a well and the well cap is used to provide a leak proof enclosure.  A well dock is also available as a device located inside the cap and used to suspend the datalogging transducer as it collects well level data.

Our well caps provide excellent tamper proof security and they're made of high impact PVC material providing a one piece enclosure that's rust and corrosion proof.  Well caps are an inexpensive low profile accessory for the series 550.
