مفتاح ضغط Fema DGM310A

Honeywell DGM310A gas pressure switches used for steam, hot water, fuel gases, and liquid fuels. Fema DGM310A differential pressure switches certified for use with gases according to DVGW G260 specifications and EN 1854 standards. Honeywell Fema DGM310A pressure switches must be used within the parameters specified in the technical documentation. High-quality stainless steel parts allow the switch to be used in various environments, but a chemical resistance test is recommended before selection. Honeywell DGM310A gas pressure switch technical data Setting range: 20-100 mbar Switching differential: 7 mbar Maximum working pressure: 0.8 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 Pressure connection: External thread G 1/2” A (pressure gauge connection) according to DIN 16288 and internal thread G 1/4” according to ISO 228, Part 1. When working with gas, the internal thread is allowed only at pressures up to 4 bar. If the pressure is > 4 bar, use a flat O-ring.
