ENDRESS+HAUSER  CLS50-A1B1

Indumax CLS50/CLS50D is particularly suitable for use in the chemical industry and process engineering. The six-decade measuring range and the excellent chemical resistance properties of the materials in contact with the medium (PFA or PE

• Concentration measurement of acids and bases
• Quality monitoring of chemical products in tanks and pipes
• Phase separation of product/product mixtures

The CLS50D digital sensor is used with Liquiline CM44x or Liquiline M CM42, while the CLS50 analog sensor is used with the Liquiline M CM42, Liquisys CLM223/253 or Mycom CLM153 transmitters.

An oscillator (1) generates an alternating magnetic field in the primary coil (5), which induces a current flow (4) in the medium. The strength of the current depends on the conductivity and thus on the ion concentration in the medium. The current flow in the medium, in turn, generates a magnetic field in the secondary coil (3). The resulting induced current is measured by the receiver (2) and used to determine the conductivity.
