Capacitive Micro Pressure Transmitter adopt original superior quality ceramic disphragm pressure sensor as the pressure signal element to sensor the gas, liquid or steam, and convert the sensed pressure signal to a standard 4-20mA current signal through electronic circuit, then 4-20mA current signal could be transmitted to the secondary instrument, computer systems for industrial process automation and control. This instrument is widely used for pharmaceutical, medical equipment, airspace and aerospace, scientific research, leakage detection, accessories of automation equipment paper, metallurgy, textile, environmental protection industry. It is an ideal choice for industry pressure process control due to its small size, easy installation
Features:
- To measure gauge pressure, absolute pressure, vacuum pressure, with wide range
- Overload is strong
- Without medium liquids, can measure micro pressure
- Can be operated with display
- Small temperature drift, sensor and Conversion circuit both have Temperature compensation function.
- With intrinsically safe prevent explode function.
- Null Point and measuring range of the metering circuit is Continuously adjustable for calibration and span shift.
- Fully-Enclosed Structure, it is suitable for long use in the situation of open and more abominable environments
