Advantage:
Controlling and monitoring of softened water quality, by comparison of waters from softener inlet and outlet, TH130 monitors safely the quality of softened water. It emits a light alarm as soon as the hardness of outlet water is near or above the threshold.
Raw water (tap water): hardness of 300 ppm CaCO₃ Threshold is set at 0.25 %: for alarming when hardness of softened water is above 0.25% of raw water hardness. It means that an alarm occurs when softened water hardness is over 0.75 ppm of CaCO₃.
TH130 also delivers a 4-20 mA signal which represents the percentage of residual hardness in the softened water, in comparison to raw water hardness.
Raw water hardness (tap water) is 300 ppm CaCO₃. Output signal 4-20 mA is set on the scale 0 ... 2 %. The value 20 mA will represent 2% of raw water hardness, in this case: 6 ppm CaCO₃.
TH130 comprises two solenoid valves that successively pass raw water and then softened water on a specific Ca⁺⁺ /Mg⁺⁺ electrode. With its hardware, the analyser contemplates the ionic activities, compares data and proceed to check the system, less or more frequently. The controller delivers information: normal operation, alarm, faulty solenoid valve, brine leakage, etc. Water samples are rejected to drain (no pressure).
After start up, once measurements are stabilized,TH130 triggers a sampling routine each 15 minutes. It is possible to trigger sampling by an external signal (counter with pulse, external contact).
