PTM300G Pressure Sensor

PTM300G high temperature pressure transmitter selects the pressure sensor with high temperature resistance as the signal measuring element. The pressure of the measured medium is transferred to the sensor through the heat dissipation structure on the transmitter. The high-precision signal processing circuit is located in the stainless steel shell, and the output signal of the sensor is converted into the standard output signal.

The whole product has passed the strict testing and aging screening of components, semi-finished products and finished products, and the performance is stable and reliable, so that the product can work stably for a long time when used for pressure measurement of high-temperature medium.


1. 316L stainless steel isolation diaphragm structure

2. Imported high temperature resistant chip is selected

3. Wide range of applicable medium temperature

4. Strong anti-interference and long-term stability

5. Direct contact measurement of high temperature medium, improve the pressure response frequency

6. Provide low pressure, medium pressure, high pressure rich pressure range

7. Vibration resistance, impact resistance, corrosion resistance
