About the MPM281PT Pressure and temperature sensor module

The MPM281PT Pressure and Temperature Sensor is a high-stability measuring device featuring isolated construction and precise temperature compensation. Encased in a robust stainless steel 316L housing with a diameter of 19mm, it utilizes a highly stable and reliable silicon die along with PT100 or PT1000 temperature probes to deliver accurate pressure and temperature measurements.

The sensor incorporates a precision-calibrated compensation circuit that provides temperature compensation and zero-point deviation correction across a wide temperature range. Pressure is accurately transmitted to the sensor chip through an isolation diaphragm and internal medium, enabling precise conversion of pressure into electrical signals. Additionally, the built-in platinum resistor measures the temperature of the medium, allowing simultaneous monitoring of both pressure and temperature.

The MPM281PT undergoes strict inspection and screening on an automated production line, ensuring excellent reliability and long-term stability. This sensor is ideal for industrial applications requiring integrated pressure and temperature measurement.
