Dwyer1900 Differential Pressure Switch Ultra Micro Differential Pressure Switch 1910-00 1910-0 1910-1

1900 Series Compact Low Differential Pressure Switches

Set points from 0.07 to 20 inches of water with repeatability within 3%

Our general range of products, combined with advanced design and construction, enables it to do the work of many large, expensive switches of the same kind. Designed for use in air conditioning systems, it can also be used in equipment such as fluids, refrigeration, ovens and dryers. For air and non-flammable compatible gases, the 1900 Series switch set point range is from 0.07" to 20" (1.8-508 mm). The set point is easy to adjust and the adjustment screw is protected within the housing, this internal location prevents misadjustment. UL, CE, CSA and FM approved.

WARNING: PRODUCT FOR AIR AND COMPATIBLE GAS ONLY

Special models and accessories:

The manual reset model 1900MR includes a special push button switch that automatically shuts off when the pressure rises beyond the range of the set point. When the pressure drops below the set point, it must be reset manually. Add -MR suffix to the range of 1910 when ordering. For example: 1900-10-MR, which is only applicable to ranges such as -1, -5, -10 or -20. There is no UL, CSA or FM approval for this option.

NOTE: The Manual Reset (MR) option is only available for single positive pressure.

A-399 Pipe Pressure Detection Kit - For use with standard and manual reset style switches, includes mounting flange, pipe and fittings.

A-329 Elbow Fittings - Brass fittings for installations requiring right angle connections, two are required for differential pressure measurements.

Explosion Proof Cast Enclosure (CN): Model 1911-CN, Explosion Proof Enclosure, NEMA-7&9; change the base model to 1911 and add the -CN suffix when ordering. Example: 1911-1-CN.
