Introduction
BS12 series piezoresistive pressure transducers adopt high-sensitivity piezoresistive silicon chip inside for pressure sensing. The chip is protected against ambient influences by a stainless steel housing
sealed with a concerntrically corrugated diaphragm.The housing is filled with silicon oil for the transfer of the pressure from the diaphragm to the sensing component. Exchanging the pressure into analog output signal.
The transducers are designed for floating O-ring seal mounting for avoiding housing induced stress,
this also can guarantees the performance over pressure.All metal parts in contact with the pressure media are made of stainless steel 316L.
Different with the universal BS12 series pressure transducers,BS12P has a amplify circuit inside the transducers which exchanges the pressure into 0.5V~4.5V output signal directly. Its flush diaphragm design makes its diaphragm cleaning easily.
They are delivered with engraved serial number. Once any problem happen on any transducer, all testing records during the whole process from raw material to the finished products is ready for tracing.

Order Note
1. It is recommended that the transducers should be installed as Suspended Mode to avoid face tight press and avoid affecting transducers stability.
2. Please pay attention to protect the diaphragm to prevent any damage or bad performance.
3. If the working temperature of Viton rubber exceeds the temperature of the rubber specification or be applied in critical environment, please contact us.
4. The material of measuring medium should be compatible with the stainless steel.If it is corrosive,pls specify its material in detail.
5.Please note in the order if you need zero pressure as negative pressure.
6. All specifications are subject to change and just for reference.Contact Gaohua for specifications and engineering drawings that are critical to your application.Drawings contained in this document are for reference only.
