Capacitive pressure transmitter with analog output

Quantité : 1   Prix : USD400

1.Description

Capacitive Pressure Transmitter is the result of a combination of self-developed anti-jamming, high stability digital circuits and the introduction of foreign Single crystal resonant silicon sensor technology. Its performance much better than our domestic metal capacitive sensor technology transmitter, and main show in the field zero stability and long-term operation stability, and rapid response.

2.Feature

Single crystal resonant silicon sensor technology

Super performance, use to measure pressure, differential pressure and temperature..

Accuracy: ±0.075%~±0.1%F.S/±0.2%F.S

Stability: ≤0.2%

Standard 4~20mA,RS-485 communication interface

Support upgrade of basic scene control technique

Little temperature effect

Little static effect

Overload can reach 2 times

Application

Compatible with 316LSS,noncorrosive liquids.

Shipping and aviation industry.

Hydraulic pressure and pneumatic control system

Apply in Petroleum industry, chemical industry, electric power, metallurgy, hydrology etc process control.
