PC112K Flush Diaphragm Pressure Sensor with Clamp
Product overview
PC112K pressure sensor adopts a single time silicon oil filling technology. The perceived pressure is transmitted to the pressure chip through the silicone oil to generate an electrical signal, and the compensation circuit corrects the pressure signal to a linear pressure signal. The clamp face diaphragm is exposed to direct pressure, which can prevent scaling, unsanitary and viscous pressure blockage. It is especially suitable for viscous fluid pressure and liquid level measurement in the medical and food industries. It is widely used in food, pharmaceutical, winemaking and other sanitary industries.
The company can customize products for customers, to make products of special structure and size. We have mature batch production lines, which can ensure production tasks be finished perfectly.

Example: PC112K-35kGI1K1H1T3
Refer to product model PC112K, with pressure range 35kPa, gauge pressure, 1.5mA constant current excitation, 1.5" clamp, 3 pieces cooling elements, and rear thread M25×1.
Ordering tips:
1 Pressure range can be selected higher or lower than actual conditions but should be within ±30%FS.
2 Pressure reference consists of gauge pressure, absolute pressure and sealed gauge pressure.
1. Gauge pressure is based on the current atmospheric pressure. Generally, it refers to the measurement of pressure which is greater than the current atmospheric pressure. Negative pressure is a special case of gauge pressure. It refers that there is such working condition that the pressure of work site is lower than the current atmospheric pressure.
2. Absolute pressure is based on vacuum.
3. As for sealed gauge pressure, PC10 uses absolute pressure die for gauge pressure product based on the atmospheric pressure of production site. For pressure range above 6MPa, gauge pressure cannot be selected, but only sealed gauge pressure. 3 Confirm the maximum overload of the applied system, which should be less than the overload protection limit of the sensor, otherwise it will affect the product life or even damage the product.
4 The commonly used compensation of the product is 1.5mA constant current compensation. Suggest selecting the option with priority.
5 The material and process for manufacturing negative pressure sensors are different from those of positive pressure sensors. So gauge pressure sensors cannot be used as substitute of negative pressure sensors.
