Technical data 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. Protection class IP 54, in vertical

position. Pressure sensor materials DNM025…DCM63 Metal bellows: 1.4571 Sensor housing: 1.4104 DCM025

– DCM 1 Metal bellows: Cu Sensor housing: Cu + Ms DCM4016/ Diaphragm: Perbunan DCM4025 Sensor housing

: 1.4301 DCM1000 Diaphragm: Perbunan Sensor housing: Brass Mounting position Vertically upright and

horizontal. DCM4016 and 4025 vertically upright. Ambient temp. at switching device –25…+70 °C,

except: DCM4016, 4025, 1000: –15…+60 °C Max. 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 screw driver. Switching differential Not

adjustable with DCM and types. Adjustable from outside with DCMV types. For values see Product Summary.
