Level switch HRH-7

• Suitable to operate / work in harsh conditions due to the high degree
of protection IP65
• Swich monitors the level changes in wells, reservoirs, tanks, tankers etc.
• It is possible to select the following confi gurations:
– one-level switch of conductive liquids monitors one level (by connecting H and D)
– two-level switch of conductive liquids monitors two levels (switches
on at one level and switched off at another level)
• Choice of function PUMP-UP or PUMP-DOWN
• Adjustable time delay of output (0.5 – 10 s)
• Adjustable sensitivity using potentiometer (5 -100 kΩ)
• Measuring frequency 10 Hz prevents liquid polarization and increased
oxidation of measuring probes
• Measuring circuits are galvanically separated from the power source of
the product and circuits of the relay contact by enhanced insulation
according to EN 60664-1 for overvoltage category III.
• Output contact: 1x changeover / DPDT 16 A / 250 V AC1
