Capacitance differential pressure transmitter

Product Description

Description of Capacitance differential pressure transmitter:

Capacitive Pressure Transmitter is the application of modern advanced technology to produce a high-tech product, the product has novel design principles, complete specifications, installation is simple, intrinsically safe explosion-proof characteristics. Especially in high precision, small size, light weight, strong resistance to vibration, easy adjustment, high long-term stability, good-way overload characteristics, etc., can be directly output 4 ~ 20mA standard signal, suitable for measuring pressure, absolute pressure, negative and level.

Specifications:
