IPSD MODEL
Industrial Differential Pressure Switch (IPSD–50) is an electromechanical device that senses changes in pressure difference between two pressure lines and provides electrical contact closures at predetermined values.
Product Description
Applications :
These switches are normally used on pressure lubricated system across the filter to get an indication or alarm when the filter gets choked. It can also be used to stop the pumpor energise / de-energise another electric circuit depending upon the actual application. It is designed for use with oil, air, water and low temperature steam. It is not designed for refrigerant gases.
Setting :
The lower changeover is set on the scale by rotating the pressure setting disc inside the control. Clockwise rotation of the setting disc reduces the set differential pressure and vice versa. The higher changeover is achieved by adding the contact differential (2.8 PSI fixed) to the lower changeover. The setting disc is visible after removing front cover. It is placed just below the LP bellows between the LP bellows and main spring.
