Pressure sensors

Description
Technical data
The DPC 1 dual pressure controller was designed for dual-line
lubrication systems that use a change-over valve controlled by an Function principle end-of-line-pressure switch unit
end-of-line pressure switch unit The controller increases the energy Operating temperature –25 to 70 °C
–13 to +158 °F
efficiency of the system by matching the operating pressure to the Lubricant oil and grease
ambient conditions As a result, the pump motor only runs for as long Operating or absolute pressuremax 400 bar, 5 800 psi

• Monitors proper function of system with regard to Mounting position any
pump and change-over valve and detects tube line leaks
• Self-adjusting operating pressure increases service cycle
of system components
• Integrated timer enables system operation
without separate controller
• Measures the absolute min and max in the main lines
• Measures the differential pressure minimum and maximum
• IP 65 protection rating and Shockproof for rigorous environments
