Conductive level regulators
The conductive level regulators by NHT are suitable for controlling the minimum and the maximum level, both input and output, of wells, tanks and cisterns. When connected to the appropriate probe detectors and inserted in the control circuits of the pump, they are able to mantain the level of the liquids within the predetermined limits. Both the the devices come equipped with insulated probes which must be placed in the liquid to be controlled. At first, with the probes free, the output relay is at rest; when the maximum level probe is reached by the liquid, the relay is automatically activated. When the level descends below the minimum level probe the relay is deactivated.
This series can be characterized by monotension or multitension output and is composed of three basic models.

LC 103 / LC 104 with normal sensitivity. Models appropriated for the control of water and in general of liquids whose conductivity is max 5 Kohm.

LC 103 / LC 104 with high sensitivity. These are the regulators most appropriate for the control of liquids with a low conductivity such as rain water. These models permit the control of liquids with a total conductivity up to 70 Kohm.

LC 103 / LC 104 with variable sensitivity. These models are indispensable for the control of liquids whose conductivity is unknown. They are suitable for liquids with a conductivity of up to a maximum of 100 Kohm.
