DESCRIPTION
HPTA2000 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, HPTA2000 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.
