Features

SS121V27 series customized pressure transducer is designed with Sendo diameter Φ19 mm sensor without signal conditioning. The sensor floats on an O-ring seal and is therefore free of any housing stresses, with a maximum pressure range of up to 1000 bar (absolute & gauge).

SS121V27 series offers two types of electrical connections. Pins or wires are optional. It has optimum media isolation for use with both harsh and benign media. A variety of versions to process connection and mechanical connection to a case can be designed according to the request. It is the ideal basis for pressure transmitters, pressure switches, or digital pressure instruments.
