BS12 Piezoresistive OEM Pressure Sensor 
Feature> Pressure range (-0.1~60)Mpa;> Pressure reference: Gauge, absolute and sealed gauge;> Constant current power supply;> Isolated construction to measure various media> OEM pressure element> 316L stainless steel material> Perfect long term stability> Different male thread connection optionalApplication·Industrial process control ·level measurement ·Gas, liquid pressure measurement ·Pressure meter ·Pressure calibrator ·Liquid pressure system & switch·Refrigeration equipment &air conditioner ·Aviation and navigation inspectionIntroductionBS12 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 housingsealed with a concerntrically corrugated diaphragm. The housing isfilled with silicone oil for the transfer of the pressure from the diaphragm to the sensing component. Exchanging the pressure into mV electrical 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. They are delivered with engraved serial number. Once any problem happens on any transducer, all testing records during the whole process from the raw material to the finished products are ready for tracing. Universal BS12U Piezoresistive Pressure TransducersThe universal BS12U Piezoresistive pressure transducer is the standard type (Diameter 19mm) in BS12 series. Strongly interchangeable outline dimension, Short leading time, Widely be used in world-wide variety of different applications. BS12-13 Piezoresistive Pressure TransducersComparing with the universal BS12U series pressure transducers, BS12-13 is designed for smaller space installation/compact size (Diameter 13mm). Assembled BS12N Piezoresistive Pressure TransducersPut general BS12U pressure transducers into the housing with standard or special thread; use O-ring or combined washer to seal; with flexible construction and strict inspecting and screening; the assembled BS12N transducers has similar application with general type transducers, it can be used for mounting and production of different pressure instruments.| Basic Specification |

Order Note1. 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. Contact us for specifications and engineering drawings that are critical to your application. Drawings contained in this document are for reference only.
