Pressure switch for gas HCD HONEYWELL / FEMA

For overpressure detection the pressure side is connected to the lower connection piece G 1/4″; for vacuum detection the pressure side is connected to the upper connection piece G 1/8″ (remove sealing clamp). For differential pressure detection, high pressure is applied to the lower connection piece (G 1/4″) and low pressure to the upper connection piece (G 1/8″). A pressure measurement connection (9 mm ø) is available for accurate setpoint adjustment. The pressure switch is tested according to DIN EN1854 and approved by DVGW for air and fuel gases according to DVGW worksheet G 260.
