Product overview
PC12K clamp type pressure sensor adopts one-time silicon oil
filling technology. The pressure felt by the diaphragm is
transmitted to the pressure chip through the silicon oil, and the
compensation circuit corrects the pressure signal into a linear
electric signal. The clamp face diaphragm is exposed to direct
pressure, which can prevent scaling, unhygienic and sticky
pressure blockage and other problems. It is widely used in
food, pharmaceutical, wine-making and other sanitary
industries as well as occasions where the measuring medium
may be fouled.
Customization is available for special structure and size of the
product. The company has a mature batch production line that
can complete production tasks in time with quality.

How to order
PC12K - 35k G I1 K1 H1 T0
Example: PC12K-35kGI1K1H1T0
Refer to product model PC12K, with pressure range 35kPa, gauge pressure, 1.5mA constant current
excitation, 1.5” clamp, no cooling fan, 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.
⑴Gauge 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.
⑵Absolute pressure is based on vacuum.
⑶As 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.
