Description
The Variohm EPT3100 Fluid Pressure Sensor is a high quality all stainless steel pressure transducer. It’s intended for use in the measurement of gases and liquids compatible with stainless steel up to 10 Bar of pressure. It is suitable for automotive, industrial hydraulics, refrigeration off-road, construction and agricultural applications.
The EPT3100 strain gauge sensing element coupled with the latest ASIC circuitry, assures excellent accuracy, choice of high level outputs and long stability, protected within a rugged, stainless steel housing. The EPT3100 high strength stainless steel construction contains non-silicone oil and no internal O’ rings. Measurements are in gauge up to 10 Bar and are backed by a one-year warranty.
This fluid pressure sensor is finished with a 3/8×24 UNF Male (Dash Size 3) thread and Packard Metripac connector (plug and pins kit available separately if required).
