  • Page 23 ® DEPOLOX 3 PLUS RESIDUAL ANALYZER Bare Electrode (Free Chlorine) Sensor Kit The flow block assembly with the sensors should be installed in a frost- protected location and, where possible, in a heated room. The sample water should provide a minimum of approximately 2 psi (0.2 bar) water gauge pressure at the measuring cell inlet.

  • Page 24: Ph Sensor Kit

    Under these conditions the sensor should give proper readings for three to six months. For connection to the DEPOLOX 3 plus electronics, refer to Dwgs. 50.560.155.020 and 50.560.155.040. The sensor requires a one to two hour run in time before a first calibration can be performed.

  • Page 25: Flow Switch

    In general, the flow switch is only connected to the digital input of the DEPOLOX 3 plus. In case of other applications, ensure that the rating of this Reed contact (100 V AC and 0.5 A) is not exceeded even for a short time.

An amplifier in the electrode shaft conditions this signal including temperature compensation and passes it to the micro- processor-based electronic system DEPOLOX 3 plus for processing. Air bubbles on the membrane may prevent chlorine from passing through the membrane, resulting in a false reading of the probe. A water jet, designed into the flow block assembly, is used to remove any potential air bubbles from the membrane.
