THP310 Industrial Grade Temperature and Humidity Atmospheric Pressure Transmitter

To ensure the stable and reliable operation of the equipment, the environmental parameters such as temperature, humidity and atmospheric pressure need to be monitored in some industrial sites, for example the environmental monitoring of vessel cabin.

THP310 Industrial Grade Temperature and Humidity Atmospheric Pressure Transmitter is specifically developed and designed for this purpose. It has a firm and durable stainless steel housing that can output temperature, humidity and atmospheric pressure signals in real time, not only with a field display, but also with a sound-light alarm output.

The temperature and humidity sensitive elements of THP310 adopt high molecular film humidity-sensitive capacitor and PT1000 temperature-sensitive resistor, which use special breathable coating and circuit injection packaging process, to ensure that the probe can withstand dust pollution and high humidity condensation environment, while having good long-term stability and precision.

      The pressure-sensitive element of THP310 uses the piezoresistive pressure sensor in a ceramic package and protected with gel. It can operate reliably and steadily within the temperature range of -40...85℃, while the metal shell is connected to the ground, so there is a good electrostatic discharge robustness.
