The Honeywell C437D-EGH is a gas pressure actuated switch designed for industrial gas system applications including safety shutoff, pressure control, and differential pressure control. Part number C437D-EGH covers a pressure range of 0 to 5 PSI (5 to 35 kPa, 500 to 3500 mm of water column) with a 1/2 inch NPT main pressure connection. The faceplate is labeled Gas A/G/LP Pressure Switch and carries both kilopascal and pounds per square inch scales for field reference during setup and calibration.
This unit is from the C437D,E,G,H series and features a SPST mercury switch mechanism. A warning label advising mercury containment and proper disposal is visible on the faceplate. Approvals visible on the faceplate include UL Listed (file 173H) and FM Approved. The item was manufactured in Minneapolis, MN. The C437D-EGH is a discontinued model; Honeywell's current Series 2000 C437D/E models serve as successor products for many of the same applications.
Item is in original cardboard box and appears unused. Mercury-containing pressure switches of this type require special handling and disposal in accordance with applicable local and federal regulations. Suitable for natural gas, air, and LP gas pressure monitoring in commercial and industrial burner systems, boiler controls, and related combustion equipment.
