Descriptions

SS121E27 series piezoresistive transducer is of all welded stainless steel construction, with integral media isolation diaphragm, no 'O' ring seals are used, maximum pressure range up to 1000 bar. The size of housing, and the pressure/screw connection can be designed according to the request.

A high performance piezoresistive silicon chip is used inside makes the SS121E27 series has a great working performance, the accuracy can be 0.25% F.S., offering improved reliability and significantly lower production costs. Two types of electrical connections pins or wires is optional. The SS121E27 series is the ideal basis for pressure transmitters, pressure switches or digital pressure instruments.
