Fema DDCM1 pressure switch

Fema DDCM1 differential pressure switches designed for precise monitoring and regulation of pressure differentials, flow control, and automatic filtration system management. Featuring a dual-chamber design with a stainless steel bellows or a Perbunan diaphragm, these switches accurately measure the difference between two applied pressures. The switching pressure is smoothly adjustable within the ranges specified in the technical specifications. Adjustments are made with reference to the lower switching point (when the pressure differential decreases), while the upper switching point (when the pressure differential increases) is higher by the amount of the switching differential. Honeywell Fema DDCM1 pressure switches can also be used in vacuum applications, enhancing their versatility. Each Honeywell DDCM1 pressure switch includes two pressure connections with clear markings, facilitating easy and accurate installation and adjustment.

Honeywell DDCM1 differential pressure switch technical data:

• Setting range: 0.2-1.6 bar
• Switching differential: 0.13 bar
• Maximum working pressure: 15 bar
• Pressure connection: Internal thread G 1/4
• Switching device: Robust housing (200) made of seawater-resistant diecast aluminium GD Al Si 12
• Degree of protection: IP 54, in vertical position
• Mounting position: vertically upright
• Ambient temperature at switching device –25…+70 °C
• 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)
