مفتاح ضغط Fema DGM325A

Fema DGM325A gas pressure switches suitable for steam, hot water, fuel gases, and liquid fuels. Honeywell Fema DGM325A pressure switches certified for gases according to DVGW G260 and EN 1854 standards. Honeywell DGM325A pressure switches must be used within specified parameters. High-quality stainless steel parts allow use in various environments, but a chemical resistance test is required. Fema DGM325A differential pressure switch technical data Setting range: 40-250 mbar Switching differential: 10 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.
