Fema DGM1A pressure switch

Fema DGM1A differential pressure switches used for steam, hot water, fuel gases and liquid fuels. The Honeywell Fema DGM1A pressure switch designed and approved for working with gases in accordance with the DVGW G260 specification and the criteria for the degree of tightening according to EN 1854. The Honeywell Fema DGM1A pressure switch allowed to be used strictly within the ranges of electrical, hydraulic and temperature parameters specified in the technical data table. Due to the high quality of the stainless steel sensor parts in contact with the working medium, the Honeywell DGM1A differential pressure switch can be used for a variety of media. However, it is necessary to carry out a chemical resistance test before selecting the device.

Fema DGM1A pressure switch technical data

• Setting range: 0.2-1.6 bar
• Switching differential: 40 mbar
• Maximum working pressure: 3 bar
• ambient temperature: -25 to 60 °C
• ambient temperature: 60 °C
• The difference in the sizes of materials operating at contact pressure (average values) when pulling the medium
• Switching: Single-pole switching
• Switching capacity: 8 (5) A, 250 V AC
• Installation position: Vertical and horizontal
