DESCRIPTION

HPTA0700 is a kind of high temperature MEMS sensor based on SOI semiconductor

materiel . Its operating temperature is -30~180°C. With advanced beam--diaphragm

structure design and stress equipartition technology adopted, HPTA0700 sensor has the

advantages of high temperature resistance, transient high temperature shock immunity,

high measuring range and high overload which make it ideal for pressure self-control

testing equipments used in aerospace / aviation, energy transportation, oil exploitation,

heat process automation in Chemical industry, metallurgical automation, etc.

HPT series 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 still can operate normally even though the environment temperature exceeds 180

℃.

HPT sensors are produced first by ion implanting the four piezoresistors 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.
