Product overview
The PC12Ⅱpressure sensor adopts food-grade oil filling
technology. The perceived pressure is transmitted to the
pressure chip through the oil to generate an electrical signal,
and the compensation circuit corrects the pressure signal to
a linear pressure signal. The product adopts flat membrane
structure, easy to clean, high reliability, suitable for pressure
and liquid level measurement of viscous fluids such as glue.
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
PC12Ⅱ- 100kPa G 4W I1 C1 H3F
Example：PC12Ⅱ-100kG4wI1C1H3F
Refer to product model PC12Ⅱ, with pressure range 100kPa, pressure reference gauge pressure,
4 wire, 1.5mA constant current excitation, pressure port M20*1.5, housing port: M24×1(Female), without
cooling elements.
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, it 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 is1.5mAconstant current compensation. Suggest to
select 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.
