Product Details

4-20mA Low cost hydraulic Micro pressure sensor

Micro Pressure Sensor adopts piezoresistive flat membrane silicon oil-filled sensing element as the signal measuring element, with stainless steel diaphragm which can be compatible with gas or dilute liquid With a flush diaphragm process connection, so it is mainly applied to general applications such as food,pharmaceutical and chemical liquid pressure measurement.

Feature:

flush diaphragm pressure range: 0~35kPa...100MPa gas or dilute liquid compatible with 316LSS high reliability and stability

Applications:

process control system medical biological products food hygiene
