Page 3: Basic Description
1 . Basic description Capacitive proximity switch CPS–24 is intended for detection of proximity or motion of solid objects. It is suitable for indication of the liquid level through non-conductive walls of vessels or on non-conductive gauge-pipes. It is excellent for liquid leakage detection in collection pits or directly on floors. The sensor state is indicated by LED. The sensitivity is adjustable by a trimmer located under a cover screw on the rear side. The design and housing materials of CPS allow the use in complicated environments (harsh, dusty, explosive, aggressive) as well as in clean environments (medical technology). CPS–24 © Dinel, s.r.o. -
Page 4: Dimensional Drawing
In the case of the use for an aggressive medium is necessary to prove the chemical compatibility of used materials of the sensor (Tab. Used materials on page 13). This guarantee ceases when the product is chemically damaged. © Dinel, s.r.o. CPS–24... -

Page 6: Electrical Connection
In the event that the switch-mode power supply is equipped with a PE safety terminal, it must be unconditionally grounded! Spark-safe devices (type CPS-24) must be powered from a spark-safe power source meeting the above-mentioned requirements. -

(sensing distance) depends on the dielectric properties or where appropriate the conductivity of the sensed material. For sensing of materials with a low relative permittivity (plastics), we recommend to individually set a higher sensitivity, or consult with the manufacturer if necessary. CPS–24 © Dinel, s.r.o. -

The level sensor is designed to be connected with supply unit type NSSU, NDSU and NLCU. If some other approved apparatus is used, its output parameters comply with above mentioned parameters, then it is necessary to include galvanic separation and/or in case of application of ap- paratus without galvanic separation (Zener safety barriers) it is necessary to provide equipotential equalisation between sensor and point of barrier earthing. For zone 0 application the present potentially explosive atmosphere of air mixture with gases, mists or vapours shall comply the following: = -20 to +60°C, p = 0.8 bar to 1.1 bar. amb Maximum input parameters: Ui = 12 V; Ii = 15 mA; Pi = 45 mW; Ci = 15 nF; Li = 10 µH CPS–24 © Dinel, s.r.o. -

Page 13: Packings, Shipping And Storage
If the device is to be further shipped, it must be wrapped in its original packaging and protected against impact and weather conditions. Store the device in its original packaging in dry areas covered from weather conditions, with humidity of up to 85 % without effects of chemically active substances. The storage temperature range is -10 °C to +50 °C. CPS–24 © Dinel, s.r.o. - Page 14 Dinel, s.r.o.
