All KPSI Transducers utilize a highly accurate pressure sensor assembly specifically designed for hostile fluids and gases. The assembly is integrated with supporting electronics in a durable waterproof housing constructed of 316 stainless steel. The attached electrical cable is custom manufactured to Pressure Systems’ specifications and includes Kevlar® members to prevent errors due to cable elongation, and a unique water block feature that self-seals in the event of accidental cuts to the cable.
The Series 300DS is CE compliant to EN 61000-6-4:2001 and EN 61000-6-2:2001 and have a IP 68 and NEMA 6P housing protection rating. All KPSI Transducer calibrations are traceable to the National Institute of Standards and Technology (NIST).

- Intermediate level ranges are available.
- Static accuracy includes the combined errors due to nonlinearity, hysteresis and nonrepeatability on a Best Fit Straight Line (BFSL) basis, at 25ºC per ISA S51.1.
- Thermal error is the maximum allowable deviation from the Best Fit Straight Line due to a change in temperature, per ISA S51.1.
- Custom VDC output levels can be provided up to 2.5 VDC less than the excitation supply voltage.
- -20ºC to 50ºC for level ranges <= 100 ft (70m) H2O when using ETFE cable.
- ETFE is a fluoropolymer (Teflon® derivative) material, Tefzel® or equivalent
