Overview

HPTM280 digital temperature and pressure integrated transmitter adopts the industry's leading and unique design structure, with built-in independent measurement of high-stability pressure sensitive elements and high-precision temperature sensing elements, which can simultaneously achieve accurate measurement of medium pressure and temperature. In addition, the product has a field display, which can alternately display pressure and temperature values, and can also be networked through RS485.

The product has been screened for long-term aging and stability, with reliable and stable performance. It can be used in places with relatively harsh environments and can meet the accurate measurement of multiple parameters at one measuring point. It is widely used in the simultaneous measurement of fluid pressure and temperature in the field of industrial process control.

Features

Parallel measurement of temperature and pressure
Up to 0.2 level pressure channel measurement
Temperature sensor front-mounted method measurement, smaller error
Breathable design makes pressure measurement more stable
Supports a variety of electrical interfaces
