701 2 Pump Controller

Pump Controller 701 is a compact DIN-rail mounted unit for level control of 1 pump and 1 alarm or for 2 pumps in alternating service. The Pump Controller 701P is supplied either complete with sensor, cable bracket or as a separate unit.

The Pump Controller 701 measures level via a hydrostatic level transmitter with a 4-20 mA feedback and is easily configured via the front panel. Suitable sensors for Pump Controller 701P are pressure transmitter types 7070, 1400, 7060 and 3400.

  • The Pump Controller 701P is supplied with a hydrostatic pressure transmitter with measuring ranges of 3, 10 or 30 m.
  • Pump Controller 701P is calibrated via the front panel. The setting values are read on a voltmeter connected to the test sockets on the front, where 0 – 3 V corresponds to 0 – 3 m / 0 – 30 m, and 0 – 1 V corresponds to 0 – 10 m.
  • Pressure transmitters 7060 and 3400 are made of polypropylene and suited for measurement in waste water and sludge.
  • Pressure transmitters 7070 and 1400 are of stainless steel with a small outer diameter and are used for clean liquids, for example in water drillings.
