MISURATORI PUNTUALI CAPACITIVI Capacitive level sensors CLS – 23 Capacitive level sensors (switches) Riels CLS–23 are designed for limit level detection of electrically conductive and non-conductive fluids in vessels, reservoirs, sumps, pipes, tanks, etc.The sensitivity of the sensor can be easily set by placing magnetic pen on a sensitive spot. The connection is done by means of two wires directly into a circuit with a relay or to binary input of a control system. • For level detection of electrically conductive and non-conductive fluids • Compact miniature performance • Easy setting by means of magnetic pen • Direct mounting to vessels, tanks, sumps, tubes • High temperature performance available • 2-wire connection directly to relay circuit (current switch) • LED state indication Sensor variants Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments Uncoated short bar electrode, for sensing of electrically non-conductive liquids (mineral and plant oils, resins, etc.). Mounting in horizontal position. Electrode length 30 mm. Insulated (coated) short bar electrode, for non-aggressive electrically conductive liquid sensing (water, water solutions). The insulation is made from polypropylene (PP). Electrode length 30 mm. Insulated (coated) short bar electrode, for moderately aggressive electrically conductive liquid sensing (chemicals, water, moderately aggressive water solutions). Higher temperature resistance than variant "11". The insulation is made from FEP. Electrode length 30 mm. Partly insulated rod electrode, for level detection of conductive and non-conductive liquids, partially resistant to vapours (water) condensation in the sensing area. The insulation is made from FEP. Vertical mounting; horizontal mounting (from the side) is possible for shorter electrodes (up to 200 mm). Electrode length from 50 mm to 1 m. Fully insulated rod electrode, for universal use, for level detection of conductive liquids (water, water solutions). Resistant to vapours (water) condensation in the sensing area and partially resistant to medium spraying. The insulation is made from FEP. Vertical mounting; horizontal mounting (from the side) is possible for shorter electrodes (up to 200 mm). Electrode length from 50 mm to 1 m. Uncoated removable rod electrode, for level detection of conductive and non-conductive liquids. Vertical mounting; horizontal mounting (from the side) is possible for shorter electrodes (up to 200 mm). Electrode length from 50 mm to 1 m. Accessories Standard – included in the level sensors price Optional – for extra charge • Extra cables (over the standard length 2 m) • Non-rewirable connector plug M12 • Rewirable connector plug M12 • Steel welding flange ON –18x1,5 or ON–G3/8'' • Stainless steel welding flange NN –18x1,5 or NN–G3/8'' Safety, protections and compatibility The level sensor is equipped with a protection against electric shock on electrode, polarity, overvoltage and short-term current overload on the output. Electromagnetic compatibility is provided by conformity with standards EN 55011 / B, EN 61326-1, EN 61000-4-2 (8 kV), -4-3 (10 V/m), -4-4 (2 kV), -4-5 (1 kV) and -4-6 (10 V). Areas of applications Detection of various types of liquids - water, oils, coolants, water solutions, etc. Suitable for metal vessels, containers, tanks, sumps, tanks, pipes. Suitability for non-metallic containers (glass, plastic containers, etc.) please consult with the manufacturer.

Installation and recommendations Applies to: CLS–23_–20, 21, 30 For top mounting (vertical position) it is necessary to keep the distances from walls and from other sensors. Installation into the auxiliary gauging (calming) tube. We recommend to keep the tube diameter.

Continuous light -Sensor is closed (switched ON) Dark - Sensor is open (switched OFF) Rapid flashing (period 0.2 sec.) *- Unrecognized upper and lower limits or setting mistake Slowflashing (period 0.8 sec.) - Short circuit at sensor output * Sensor for each flash of the LED switches its output on for approx. 3 ms.This period is sufficienti/ short to avoid unwanted switching of relay contacts. For binary inputs, we recommend to set the fìlter so as not to respond to pulses shorter than 3 ms. Order code Length of cable in meters (variarti "A") Ptocess connection: N - Normal (for...
