PMR 5 / PMR 10
Minimum and maximum pressure switches with manual reset for heating systems


• Safety pressure switches for heating systems applications
• The devices automatically stop the heat generator when a pre-set water pressure limit is reached
• Reset is exclusively manual by pressing the manual reset key after the pressure has returned by at least 0.4 bar within the shutoff value
• External graduated scale on the instrument
• Double normally closed electric contact (PMR/5EU) or normally open contact (LPR/5) in brass alloy with Ag-Ni coating
• Terminals with M4 screws and 8x8 mm pressure dice
• NBR rubber membrane with textile insert
• ¼" F hydraulic connection made of galvanised steel
• Standard protection degree IP 44
• Tear resistant cable clamps
• Maximum fluid temperature: 110°C
• Max ambient temperature 55°C

APPLICATIONS: Pressure switches for heating systems, Pressure switches for firefighting systems
