Dwyer Instruments 1900-5MR "1.4/5.5"" M/R Diff. # Switch"

The 1900-5MR 1.4/5.5 M/R Differential Pressure Switch is an accurate way to monitor the pressure difference between two points. The red and black LED indicators show "NORMAL" and "DEFECTIVE" pressure as they change color from green to Red. The red and black case can be used in dirty or dusty environments, with its IP69K (NEMA Type 6) rating. The metal end caps are securely fastened with a 1/2"" diameter hex socket head bolt.

The 1900 Series 1.4/5.5" M/R Differential Pressure Switch is designed to use in an air or general service where the plumbing connections are limited, it is constructed using a cast frame for strength and is available in a bake-prected non-corrosive finish. This switch offers accuracy of ± 3% at 35 psig (0.21 bar) and durability for long life through design and construction.

The DWYER1900-5MR is a 1.4/5.5"" differential pressure/differential manometer adjustable ""M/R"" switch from Dwyer Instruments. This switch has an adjustable 0 to 10 inch of water (0 to 25 cmH20) full scale and two 1/8"" female NPT set screws for connecting tubing.

A. 1.4 to 5.5 Volt Bipolar or Differential Pressure Switch with a wide operating range of 20 to 90 psi (137 to 623 kPa)

This dual function magnetic-inductive differential pressure switch dually monitors the pressure difference between two inlet ports, switching the contact point as the pressure differential varies from 1.4 to 5.5 inches of water column (5 to 25% of full scale). A beautifully made, silver encased brass and bronze gauge provides incredible visibility of the setpoint and gives a classic look to this pressure switch.

Sensor type R Differential Pressure Switch with 5.5"" ZERO and 4"" Full-SCALE ranges. Brown single pole snap-action rated @ 3 Amps, 60 VDC at 250°F (-40 to 80°C) & maximum switch opening of .04"WC (
