Fema DCM25 pressure switch

Honeywell Fema DCM25 differential pressure switches designed for measuring and monitoring overpressure. Fema DCM25 gas pressure switches versatile and can be applied in a wide range of fields, including general mechanical engineering, the printing industry, and pneumatic and hydraulic systems. One of the key features of these pressure switches is that they calibrated for pressure drop. This means that the set pressure value on the scale corresponds to the activation point when the pressure decreases. The reset point is then higher by the amount of the switching differential, ensuring precise and reliable system control.

Honeywell DCM25 pressure switch technical data

• Setting range: 4-25 bar
• Switching differential: 1 bar
• Maximum working pressure: 60 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
