Siemens Capacitance Switch Level Capacitance, Relay Output, Vertical, Stainless Steel Body

A capacitive switch is a sort of touch-controlled electrical switch that works by estimating change in capacitance. It works in same way as regular capacitive cell phone: when you contact the surface — assuming you aren't wearing gloves — a little electrical charge is exchanged from your body to the switch, which in this manner causes an adjustment in capacitance. The switch recognizes this change, reacting with the suitable order.

First of all, there are no mechanical segments in a capacitive switch, bringing out a more drawn out life expectancy when contrasted with their mechanical partner. Capacitive switches can withstand a portion of the harshest situations, including open air conditions. When the residue or dampness is a worry, capacitive switch is presumably the best alternative for an electrical switch. Important thing to remember is that they require direct contact with a conductive object to operate.

• Patented Active-Shield technology so measurement is unaffected by material buildup or nozzle interference is active shield section

Pointek CLS 300- Capacitive Switch from Siemens provide accurate, reliable, repeatable level detection. The robust design of heavy solids applications where abrasive materials occur as in the mining industry. The fully potted electronics are unaffected by condensation, dust or vibration. Wetted parts are made of stainless steel with a PFA shield for high chemical resistance, and of ceramic and stainless steel for high temperature version. Materials with low or high dielectric constants can be accurately detected. The unique Active Shield suppresses interference from material buildup or long installation nozzles. The unique modular design of the Pointek CLS300 provides a wide range of configurations, process connections, extensions and approvals to meet the temperature and pressure requirements of specific applications. The modular design makes ordering easier and reduces stocking requirements. A wide range of probe configurations are available, including rod and cable versions.

• Liquids

Simens CLS300 Pointek range provide accurate, reliable, repeatable level detection. Inverse frequency shift technology uses the inverse relationship between capacitance frequency to monitor fluid level. Small changes in level result in a large change in frequency resulting in excellent accuracy. The Pointek CLS300 is ideally suited to harsh and physically demanding conditions such as those in milling, mining, chemical industries and where moderately high pressure and temperatures are likely.
