The Total Error Band specification (±0.25% FS) over the complete operating temperature range (-20 to 85ºC) of the KPSI 342 eliminates the user having to combine multiple performance specifications to understand the total accuracy of the transducer.  Every KPSI Transducer utilizes 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 and includes paraaramid synthetic fiber 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
