Description
PS19A industrial pressure sensor is a standard and common sensor applied in air and chemi-industry, liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. Silicon Oil-filled and isolated from measured media by a stainless steel diaphragm and body. The most important specification for industry application is long term stability.
The PS19A sensoris designed for industry application with perfect long term stability. The thickness is smaller than PS19 which suitable for limited space assembling.
