High temperature sensor is a kind of pressure sensor commonly used in industrial practice. It is widely used in various industrial automatic control environments. The working principle of the high temperature sensor: the pressure of the wind pressure sensor acts directly on the diaphragm of the sensor. The diaphragm produces a micro-displacement proportional to the pressure of the medium. The resistance of the sensor changes. And the electronic circuit is used to detect this change. And The conversion outputs a standard signal corresponding to this pressure. Extended reading: High Temperature Flow Meter
