Pressure switch, electronic
The electronic pressure switch has a measuring cell that works according to the strain gauge principle. The measuring cell signal is digitalized and processed in the pressure switch's processor. The processed signal is output as a voltage, current or switching signal at the connector plug. The integrated digital display shows the measured pressure. The pressure is shown in the selected unit (bar, psi, MPa).
The pressure switch has two switching outputs and one analogue output. The control elements of the pressure switch can be used to select and set the characteristics of the outputs in the basic setting menu. Each switching output can be set as either an N/C or N/O contact.
