OVERVIEW

The Genspec GS4000 series of general-purpose pressure transducers is designed for applications where economical price and reliable pressure measurement is required. Incorporating bonded strain gauge technology and utilizing unique manufacturing techniques results in a low cost, high quality transducer ideal for O.E.M. applications. 

Constructed from stainless steel with 17/4 PH stainless steel diaphragm for ranges above 20 bar, and a ceramic diaphragm for lower ranges, the GENSPEC series of transducers are of a robust yet compact design. Applications include the continuous monitoring of oil, gas, water, and other liquids in a wide range of industries. 

GENSPEC transducers are compatible with the PM8000 range of panel meters and controllers to produce a simple low cost and accurate pressure measuring and control system. 

Available in pressure ranges from 0-0.5 bar to 0-700 bar (0-7.5 psi to 0-10,000 psi), gauge or absolute and electrical outputs 0-2 mV/V, 0-5 Vdc, 0-10 Vdc, and 4-20 mA (two wire).
