IQ Sensor Net System IQ Sensor Net Cleaner Head Module

Overview Specifications Documentation & Tools ;


The WTW MIQ/CHV PLUS module is a magnetic valve module for automatic controlled cleaning via compressed air for the WTW 2020 XT

Product Features

Module for automatic compressed air cleaning, controlled by relays or the IQ SENSOR NET. Compressed air cleaning for sensors - this IQ SENSOR NET module make this possible, simple installatoin included:

  • Fast function expansion - compressed air cleaning is quick and uncomplicated to install
  • Low maintenance – due to automatic sensor cleaning
  • Easy mounting - the modular design saves money, time and work

The expansion of your IQ SENSOR NET by automatically controlled cleaning functions: With the solenoid module MIQ/CHV PLUS this is as easy as the system expansion itself.

Compressed air cleaning is especially applied at heavily polluted locations, e.g. inlet of a wastewater treatment plant. Typical sensors for using compressed air cleaning are our ion selective sensors VARiON®, AmmoLyt® and NitraLyt® and the optical UV/UV-VIS probes NitraVis®, NiCaVis® and CarboVis®.
