Dwyer - Timer Boards

SERIES 2000 MAGNEHELIC® DIFFERENTIAL PRESSURE GAGES

Indicate Positive, Negative or Differential, Accurate within 1%

No Power Required
Low Cost
Used in Isolation/ Hospital Environments and Temporary Units (no power required)

Select the Series 2000 Magnehelic® Gage for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Select the -HA High Accuracy Magnehelic® Gage option for an accuracy within 1% of full scale, located below in the Product Configurator. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.

NIST CALIBRATION available.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Series AT-2000 for ATEX approved.

California Residents:  Proposition 65 WARNING.

Photohelic Control Panel

PHOTOHELIC CONTROL PANEL


Process Environments can custom design the appropriate control panel for your dust collection system or ventilation fan requirements.  We specialize in Photohelic control panels that are designed for "on demand" jet-pulse cleaning, which will extend filter life and reduce compressed air consumption, both important considerations for an efficient filtration system:

Panel Components Include:
Photohelic gauge mounted in panel door
Magnetic motor starter(s)
230-460/120v CPT 
Solid state timer control board
"Dwyer" Photohelic gauge for "on demand" pulse cleaning 
On/off push button(s) with indicator lights 
All fuses and heaters 
Bulk-head fittings for air tubing 
Prewired 
 
Options:
"Soft Start" motor starters 
 Inverters 
 Fractional hp starters for rotary valves or screw conveyors 
 Auto/manual switch for "off line cleaning" 
 Circuit breaker disconnect 
 Alarm systems for smoke, spark or explosion detection 
 Zero-speed switch alarm for conveying equipment 
 Delta P & Delta P Plus Control Panel

Delta P & Delta P Plus Control Panel

Donaldson Torit Delta P & Delta P Plus Controls


These Controls are solid-state products providing pressure drop measurement, digital display, and pressure drop control with an alarm function. Designed to provide accurate and dependable control of a pulse-cleaning timer, starting and stopping the cleaning process at the limits you choose. The Delta P and Delta P Plus are available as standard equipment on the Downflo Oval, Downflo II, Downflo WorkStations, Dalamatic, Modular Baghouse, and Electrical Control Panels

Process Environments can custom design the appropriate control panel for your system requirements.

For general ventilation systems, it may be advantageous to interlock specific fans for different areas of the building.
