Product Description

With the demand of measuring pressure of liquids and gases, we have manufactured piezoresistive Diffused Silicon Pressure Sensor. It is made from high grade strain gauges with durable capacitor that provides resistivity and high performance. In addition, new diaphragm technology measures the different pressure at the end and transfer the required output signal. The silicon sensor mounted on the diaphragm measures the pressure and sent the signal through the silicon sensor. Diffused Silicon Pressure Sensor is arranged in different bridges to estimate the pressure and transfer high to low voltage electric signal. This pressure sensor is long lasting, efficient and effective in giving high operation performance.
