Conductivity Level Switches

Product Details:

Three different variations of the Conductivity Type Level Switch. Single probe Sensor, is a single level conductivity sensor. This works with a metal tank that is grounded and used to complete the circuit of the sensor. When the water level reaches the probe, the sensor is than activated by having the ions in the solution complete the circuit between the probe and the tank. 2 probe sensor , the tank does not need to complete the circuit. The ions in the solution bridge the two probes together once both probes touch the liquid. 3 probe sensor ,is a multi-level sensor which can be grounded by the tank, and also doesn’t need to be. By having two probes at the same length, the tank will not need to be grounded. Each subsequent probe will complete the circuit in reference to the longest probe, allowing for multiple liquid levels to be detected on a single sensor. There are a number of advantages that these sensors have compared to tradition liquid level sensors. There are no moving parts and relies on a complete circuit for actuation. Generally less expensive equipment materials and installation Can incorporate multiple probes for multiple levels of control Minimal maintenance due to simplistic design which also prevents fouling of the probes.

Product Details:

Conductivity Flow Switches are based on the principle of measuring level through the electrical properties of the process material. The conductivity based level switches and sensors sense the level of water or other conductive liquids that have free ions.

These switches are successfully used in processing plants to serve the following applications:

• To avoid overflow
• For maintaining a constant level to avoid material wastage
• For switching off pumps when running dry and indicating an empty tank to avoid wear and tear and production stoppage
• The Level Switch is available in single / multipoint
• No moving part, free from maintenance
