The pressure switch module is a component of pressurized controls for zone 1/21.For zone 1/21 applications, variants with different orifice sizes are available and can thus be optimally selected for the protected Ex p volume.The function of the pressure monitor module is on the one hand to measure the flow in connection with the Ex p control unit and on the other hand it serves as a pressure safety valve.
