The EDS 300 is a compact, electronic pressure switch with integrated digital display. The integrated pressure sensor is based on a measurement cell with thin-fi lm strain gauge on a stainless steel membrane. Four different output models are available: with one switch point or with two switch points and both models can also have an additional Analog output signal 4 to 20 mA. The switch points and the associated hysteresis can be adjusted using the key pad. For optimum adaptation to a particular application, the instrument has many additional adjustment parameters, e.g. switching delay times, N/O / N/C function of the outputs.
