Flameproof Pressure Switches

DAG Pressure switches are diaphragm operated, fixed differential type. Diaphragm movement is transferred to an SPDT switch, which gives (NO-NC-COM) change-over contacts. A counteracting spring is used to achieve the required settable range. Set point adjustment can be done internally using a spanner. Turning in the adjuster (from right to left) increases the pressure setting & vice-versa. Calibration has to be done against a Pressure gauge. (We do not provide an indicating scale due to its high inaccuracy, aging effect & believe that safety settings should be set against a test gauge only).

DAG Pressure switches are diaphragm operated, fixed differential type. Diaphragm movement is transferred to an SPDT switch, which gives (NO-NC-COM) change-over contacts. A counteracting spring is used to achieve the required settable range. Set point adjustment can be done internally using a 16mm spanner. Turning in the adjuster (from right to left) increases the pressure setting & vice-versa. Calibration has to be done against a Pressure gauge. (We do not provide an indicating scale due to its high inaccuracy & believe that safety settings should be set against a test gauge only).

Electronic Pressure Switches

DAG Pressure switch carries a Relay which gives (NO-NC-COM) change-over contacts. Turning in the Electronic adjuster (from right to left) increases the pressure setting & vice-versa. An Electronic adjustment is provided to facilitate Differential adjustment. Calibration has to be done against a Pressure gauge / Manometer

 Industrial Pressure Switch - Adjustable Differential
 

DPIS Series pressure switches are usually used with fluorinated refrigerants to control the pressure of compressor in refrigeration systems. It can also be used in air oil and water. Internal Microswitch ensures reliable switching. It is provided with a standard Mounting Bracket.
