20DP-50: 2" Differential Pressure gage; 0-50 psi (05700388)

20DP-50: 2" Differential Pressure gage; 0-50 psi (05700388)

The 25DP series mechanism is enclosed in a steel case coated to resist corrosion. The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts have self-cleaning motion to ensure electrical continuity.

Features:

• Constant visual indication of the condition of your filter is shown on the dial.
• Two instruments in one with an accurate indicating gage and adjustable p.s.i.d. limit switch reduces inventory and installation time.
• Adjustable contact lets you set the monitoring range of the gage. The contact is tamper proof and can be set only with a 1/16 Allen-head wrench.
• All gages are made of durable materials allowing them to withstand rugged applications.
• Early filter changes cost you money and increase the risk of contaminants entering the system. A filter restriction Swichgage instrument will let you know when to change the filter and maintain peak efficiency.
