Product Description

<sup>HPTM280 protective temperature-pressure integrated transmitter adopts diffused silicon piezoresistive pressure sensor with high stability and reliability and PT100 as signal measuring element, and through automatic test and laser resistance adjustment process for wide temperature range performance compensation, can get liquid level and temperature signals at the same time.The product has been strictly screened by the process of long-term aging and stability assessment, and its performance is stable and reliable.

The product can be used in the situation where the working environment is bad and the pressure is required to be displayed on the spot. It is widely used in the pressure measurement of mechanical, metallurgical, petrochemical, electric power and other industrial processes.</sup>

Product Features

 

• Pressure and temperature are measured in parallel
• Temperature sensor is placed in front for smaller error
• Temperature probe is supported
• On-site display, alternately displays pressure and temperature
• RS485 communication
• Optional built-in lithium battery power supply
