Product overview
PC12K 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.

How to order
PC12K - 35k G I1 K1 H1 T0
Example: PC12K-35kGI1K1H1T3
Refer to product model PC12K, 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.
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.
