Micro-pressure diaphragm electric contact pressure gauge
Product Introduction
BX series diaphragm electric contact pressure gauge adopts diaphragm as pressure sensitive element, and diaphragm of different materials can be selected according to different measuring media. This instrument is mainly used for the industrial process of gas, liquid pressure micro pressure measurement, especially for corrosive viscous medium (non-solidification, non-crystalline} micro pressure measurement, and through the instrument pointer contact with the set pointer contact (disconnect) control system circuit switch, in order to achieve automatic control and automatic alarm function.

Product characteristics
The minimum measuring pressure can reach 10KPa. 316Ti and PTFE can be selected according to the anti-corrosion requirements of different measuring media.
