Hawk Measurement is introducing a new line of point level switches for conductive liquids. This type of switch is suitable for any situation where it is necessary to check the level of a liquid in a tank, including high or low level alarms, constant level control, pump control, and empty tank detection. A low voltage AC signal is applied between the probe electrode and the tank wall (or reference electrode in case of a non-metallic tank). When the liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the metallic tank wall/reference electrode. Current flow due to the conductive path is sensed amplified and use to switch a relay for indication or control purposes. Conductivity Switches are suitable for most applications that involve a conductive liquid, including food and beverage processing, chemical, oil and gas, paint, paper, pharmaceutical, and water and wastewater treatment. The GLADIATOR Conductivity Switch Series has been designed to be user-friendly and reliable. Calibration and setup are simple. The unit has no moving parts, so it is maintenance-free.
