Features

The HTP high temperature pressure sensor module series is a MEMS sensor based on SOI semiconductor material. The sensors have been widely used for measuring diesel spray pressure in the self-control testing components of diesel engines in vehicles and vessels. HPT sensors can operate in environments where the temperature exceeds 180℃.

HPT sensors are produced first by ion implanting the four piezo resistors into silicon. The four resistors are connected in a Wheatstone bridge arrangement, whereby two resistors increase with positive pressure while the other two decrease in resistance. When pressure is applied to the device and two ports of the resistor bridge are supplied with power source, the other two ports will output an electric signal which is directly proportional to pressure. Stress equipartition technology is introduced into the design of die, making the device more robust against high overload. Furthermore, the resistors are isolated with insulating medium which guarantees the high steadiness of sensor device.
