GTP-8980 has a Normally-Open switch. The switch closes upon high differential pressure. If the cable to the controller is cut, high differential would never be detected. For a system with a normally closed switch, see GTP-8980B.
If differential pressure suddenly increases or a facility is operated without personnel monitoring the differential pressure, filter element failure can occur. This new switch is unique. It adds differential pressure control at a low cost using a non-powered proximity switch. This simple double-sealed switch is ideal for use in PLC (miniature computer) and relay controlled systems. The connection box is rated NEMA 4X.
Control operations are also available if you don’t plan to use an external control. We have weather-tight and explosion-proof versions available on GTP-8980B models.
We strongly recommend a 3-way test valve for properly testing the Gammon Gauge™ and Proximity Switch and/or system.
Any Gammon Gauge™ can be converted to include the new proximity switch.
