ESS320 Differential Pressure Sensor
ESS320 Differential Pressure Sensor is a standard and most popular sensor applied in air and liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. The housing is fluid filled with silicon oil for pressure transmission. The most important specification for industry application is long term stability.
ESS320 sensor is designed for industry application with perfect long-term stability
The diaphragm diameter has tight relation with pressure measured. Low pressure requires large diameter and high pressure needs small diameter. This is caused by oil expansion during temperature changing.
It creates internal pressure due to the resistance of the diaphragm. The smaller diaphragm will create large internal pressure, and it is difficult to make zero compensation.
ESS320 is available ranges 0-2.5Mpa
