Conductivity based level switches suit most processes with conductive liquids.

Models NS (standard sensitivity the best for waters): In the case of wells with a diameter max of 100 mm the NS model probes should be positioned in such a way that there is not more than 2m between the lowest and the highest (sufficient to protect the pump). For wells with a larger diameter, the probes can be set at a greater distance, there are no limits for tanks. To conclude, liquids with a total resistance of 5.6 Kohm. max can be well controlled. The control box can be placed at a distance of up to 1,000 m from the probes.

Models AS (high sensitivity): To control liquids with low conductivity, rainwater for example the AS type is particularly suitable. These models permit liquids with a very high total resistance up to 70 Kohm., to be controlled.

Models SR (adjustable sensitivity): For the control of conductive liquids with unknown conductivity this model is essential which controls up to 100 ohm.

Electrode holders are singles – mounted on cables- or rigid 3, or 5 holders with 6mm SS  [or other] electrodes – see separate product page
