Esterline Corporation today announced the sale of its Hampton, VA-based Pressure Systems, Inc. (PSI) subsidiary to Measurement Specialties, Inc.

Pressure Systems, Inc. (PSI) is pleased to announce that the waterMONITOR series in our line of KPSI™ Level and Pressure Transducers is now RoHS compliant.  As a responsible supplier of environmental instrumentation, we are keenly aware of the importance in manufacturing products that are safe to operate and harmless to our environment.

Pressure Systems, Inc., has added a wireless compatible model to its comprehensive waterMONITOR line of KPSI Transducers. This new waterMONITOR is uniquely configured for environments where the transducer is permanently installed and used with wireless transmitters to broadcast data.  Available in two versions, the 552 and 553, these waterMONITORs are powered via a factory-attached cable assembly that can be connected to the DC voltage source used by the wireless equipment, thus eliminating the need for an on-board battery and its periodic replacement.  This feature enables a variety of power options, including solar energy, solar with DC back-up, AC with DC back-up and others requiring little, if any, field maintenance.

Pressure Systems assembled and tested a configuration in which its Series 550 waterMONITOR submersible datalogging level transducer is accessed over the Internet using cellar modem and PSI's K-ware application software. Although PSI used a particular communication service provided and compatible hardware, similar configurations can be replicated using different providers and hardware as desired by the user or more suitable for their locale.

KPSI's Series 810 vent filter is a replaceable de-humidifier intended for use with our submersible level transducers. Designed specifically for those high humidity environments where water vapor may condense in the vent tube, this device protects sensitive electronic components from mildew, corrosion, rust and other forms of deterioration while at the same time preventing the formation of a liquid column.

The waterMONITOR integrates Pressure Systems’ highly acclaimed submersible KPSI™ Transducers with an embedded, power-saving, datalogging circuit optimized for operation in a wide variety of wireless environments. Employing Pressure Systems’ industry recognized competency for sensor packaging and compensation, the waterMONITOR offers the highest level of accuracy available, including meeting the demanding requirements of the USGS Office of Surface Water (OSW) accuracy specification for stage monitoring.

Hampton, VA, March 2004 - Pressure Systems, Inc., manufacturer of KPSI™ Level and Pressure Transducers, has unveiled a new re-rangeable submersible hydrostatic level transducer that delivers outstanding sensor compensation and the ability for users to turn down the full-scale output of the transducer by as much as 10:1.

Pressure Systems, Inc., manufacturer of KPSI Level and Pressure Transducer, has introduced a line of small-bore submersible level transducers that incorporate the latest in Application Specific Integrated Circuit (ASIC) technology. The use of the ASIC greatly diminishes the effects of temperature changes and dramatically improves overall accuracy.

A team of Engineering students from Virginia Tech recently competed in, and won the 2002 Human Powered Submarine contest held in Escondido, California. The worldwide competition pitted teams from top Engineering schools vying for awards such as Best Overall Design, Innovation, Best Presentation, Construction, Safety, and Speed. The Virginia Tech team placed first, second, or third in all categories and was awarded the Best Overall Engineering Award (top prize) for their efforts.

Pressure Systems, Inc., manufacturer of submersible and above ground transducers, has added a new pressure transducer with Modbus protocol (RS-485 command/response) to its family of smart KPSI™ level transducers. The submersible Series 510 supports the operation of multiple devices through a single intrinsically safe barrier.

Hampton, VA: September 2001 - Pressure Systems, Inc., a leading manufacturer of submersible and above ground transducers, has added a temperature output option to its extensive line of KPSI™ level transducers. The new option enables the transducers to monitor the temperature of the measured process in addition to measuring level and pressure. The temperature output option is ideal for a wide range of tank and well level control and monitoring applications including oil and gas, as well as water and wastewater.
