Series DCTE Photohelic® Switch/Gage On-Demand Cleaning Controller

Reverse Pulse-Jet Cleaning Initiated by Differential Pressure

The Photohelic® Pressure Switch/Gages On-Demand Cleaning Controller provides a simple, complete dust collection control all in one enclosure. The Photohelic® controller combined with the DCT500DC Timer Control provides a timed energization of solenoid valves when the differential pressure indicates filter cleaning is necessary. The operator can easily set the cleaning initiation and duration by adjusting the 2 set point knobs on the front face of the Photohelic® controller. Solenoid valve sequencing is also easily set via two potentiometers inside the enclosure on the timer board. A three position switch on the front of the enclosure offers cleaning versatility by allowing the user to select between on demand or continuous manual cleaning. The Photohelic® controller is pneumatically connected with tubing to fittings on the enclosure. All that is required for start-up is connection of tubing from the process to the external fittings on the enclosure, and wiring the solenoid valves to the timer board.

Questions

Question
What restrictions, if any, are imposed for the Magnehelic® and Photohelic® gages in vacuum service?
Answer
In applications involving higher vacuums than 20" Hg, leakage due to gage housing porosity becomes the limiting factor.
