Fema DCM3-301 gas pressure switch technical data

• Setting range: 2-2.5 bar
• Switching differential: 0.1 bar
• Maximum working pressure: 16 bar
• Pressure connection: External thread G 1/2 (pressure gauge connection) according to DIN 16 288 and internal thread G 1/4 according to ISO 228 Part 1
• Switching device: Robust housing (200) made of seawater-resistant die cast aluminium GD Al Si 12
• Degree of protection: IP 54, in vertical position
• medium temperature: The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Temperatures may reach 85°C for short periods. Higher medium temperatures are possible provided the above limit values for the switching device are ensured by suitable measures (e.g. siphon)
• Mounting: Directly on the pressure line (pressure gauge connection) or on a flat surface with two 4 mm Ø screws
• Switching pressure: Adjustable from outside with screwdriver
• Contact arrangement: Single-pole changeover switch

Honeywell DCM3-301 pressure switch calibrated for falling pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at falling pressure. The reset point is higher by the amount of the switching differential.
