Pressure switch
Teddington Controls

The 37000 Series has been designed for the control of pressurised systems up to 450lbf/in2 (30bar). Applications include refrigeration plant, water systems, air compressors, pressurised central heating systems, beverage dispensers and process control.

The 37000 range of pressure switches are versatile and robust, with easily adjustable range and differential settings (The differential can be adjusted independently of the range setting). The pressure switches are made up of three elements, the case, the pressure unit and the switch. The pressure unit is a seamless brass bellows used on refrigeration or pressurised heating system applications. A restrictor is incorporated into the pressure element to minimise the effect of pump pulsations. The switch is a single pole change over switch that enables wiring for make on rise or break on rise. Automatic and manual reset versions are also available. The cable entry is suitable for a 16mm cable gland.
