مفتاح ضغط Fema DGM306A

Fema DGM306A differential pressure switch designed for operation with steam, hot water, fuel gases, and liquid fuels. Honeywell Fema DGM306A gas pressure switch comply with standards DVGW G260 and EN 1854 for gas applications. It is recommended to conduct chemical resistance testing before selecting and applying the device. Honeywell DGM306A pressure switch technical data Setting range: 15-60 mbar Switching differential: 6 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.
