limitron Hardness monitoring unit

Producer

The limitron automatic hardness control device without its own controller is installed in the feed of the reverse osmosis system and serves to protect the membranes by continuously monitoring the soft water for residual hardness. The measuring principle is based on resin shrinkage or expansion, so the device does not require any chemicals or water. The potential-free change-over contact of the limitron is connected to the corresponding digital input of a reverse osmosis with microprocessor controller or with PLC.
If the limitron hardness control unit is to be supplied already installed in the reverse osmosis system, the article "Installation limitron in RO system" (art. no. 370 078) must also be ordered.

Benefits

  • Proven and reliable hardness control device
  • No use of water and chemicals
  • No complex maintenance and calibration required
  • Easy replacement of the shrink resin sensor

 

Applications

  • Installation after softening plants to protect a downstream reverse osmosis from hard water breakdown

 

Protection class:
IP 54
Contact:
floating
Conditions of use:
An overpressure protection must be installed in the feed water line upstream of the hardness control unit. The spare sensor must be flushed with soft water before installation and soaked in soft water / permeate when stored. When connecting the potential-free changeover contact to the control unit of the reverse osmosis, the maximum contact load (see technical data) must be observed.
