The Total Error Band specification (±0.25% FS) over the complete operating temperature range (-20 to 60ºC) eliminates the user having to combine multiple performance specifications to understand the total accuracy of the transducer.
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 or titanium. 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. Each transducer is shipped with our latest SuperDry™ Vent Filter that prevents moisture from entering the vent tube for at least one year without maintenance, even in the most humid environments.
The Series 340 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).
