Kuhnke 60.073 Series Adjustable Pressure Switch.
The 60.073 series pressure switch from Kuhnke is suitable for all non-aggressive media; a double membrane ensures an airtight separation between electromechanical parts and the pressure chamber.
A set of changeover contacts (SPDT) which are diaphragm controlled offer a fast response time with switching frequencies of up to 5Hz. There are four options to choose from, each characterised by its switching pressure and electrical rating, please see the data sheets for further information.
The body of the pressure switch - constructed of a moulded plastic material, the base of aluminium, and the seals of Viton. The operating temperature is 0°C to +60°C; the maximum input pressure is 10 bar. Electrical connections are at the top of the pressure switch; a plug can be used to connect the contacts to a power source. A set screw allows for setting the desired pressure, and a locking nut prevents tampering.
An M5 threaded port sited on the underside of the switch for pressure input. A long threaded can bar inserted through the base should several pressure switches require mounting alongside one another. There are pre-drilled M4 threaded holes in the mounting plate so that the switch can be firmly attached to a flat surface.
