Fema HCD6003 pressure switch

Fema HCD6003 pressure switches suitable for neutral and non-aggressive gases. Honeywell Fema HCD6003 pressure switch can be used for monitoring overpressure and differential pressure. 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. Honeywell HCD6003 pressure switch tested according to DIN EN1854 and approved by DVGW for air and fuel gases according to DVGW worksheet G 260.

Honeywell Fema HCD6003 differential pressure switch technical data:

• Setting range: 0.2-3 mbar
• Switching differential: 0.3-0.5 mbar
• Maximum working pressure: 100 mbar
• Pressure connection: Pressure connection for overpressure: G 1/4″ internal thread. For vacuum and differential pressure: G 1/8″ internal thread
• Switch housing: Diecast aluminium
• Medium temperature: -15 to +60 °C
• Mounting position: Horizontal with connection pieces pointing downwards
