Capacitive Pressure Transmitter Differcial Pressure Transmitter

HMTPT300 Capacitive Pressure Transmitter
1. Feature
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. The pipelines have no affect action on null point and measuring range
Fully-Enclosed Structure, it is suitable for long use in the situation of open and more abominable environments.
