Carlo Gavazzi Industri A/S CD34CNFLFxxx CD34CNFLFxxx ENG 03/08/2020 Capacitive sensor, Foreground Suppression

Description

The CD34.. capacitive sensor is designed for detecting water-based (conductive) liquids through a non-metallic container wall, and it automatically adapts to various thicknesses of plastic or glass walls. The universal mounting brackets allow the sensor to be fixed on various tubes or containers. Strong, compact housing with IP69K ratings and ECOLAB approval for wash-down applications. The sensor will function out of the box in most applications, and teach-in capabilities are available for adapting the sensor to more challenging applications. Main features

• Compact housing
• Supply voltage: 10 to 30 VDC
• Output: 100 mA, NPN or PNP preset
• Make or break switching function
• LED indication for output and power ON
• Protection: reverse polarity, short circuit and transients
• Cable and pigtail M8 plug versions
• Excellent EMC performance
• IP65, IP66, IP67, IP68 and IP69K for hose-down

applications

• cULus
• Ecolab Main functions
• Detection of water-based fluids inside a container or tube without direct contact with the fluids.
• The sensor detects the liquids reliably while compensating for residue film, moisture or foam build-up from liquids such as water, milk, body fluids (blood), acid- or alkaline solutions with conductivity as high as 50 mS/cm inside or outside the container wall.
• Flexible and fast universal mounting bracket.
• The sensing principle detects only the level of the liquids while ignoring foam, film or build-up that would cause standard capacitive sensors to detect faultily.

Teach by wire Out of the box (Factory settings): Typically, the sensor can be used without any additional calibration; it is designed to work with plastic tank walls of approximately 0,5 to 6 mm in thickness and glass walls of approximately 0,5 to 4 mm in thickness. It is important that the glass or plastic is nonconductive. Calibration: If the factory settings are insufficient, the sensor is teachable to either Full or Empty. Calibration Full: The sensor switch point is set below the actual detection value to ensure that slight changes in the application will not affect the sensing performance. In most applications, the full calibration on a full tank or tube will be sufficient. In critical applications with large variations in media type and temperature, it can be an advantage to teach the Full level with approximately 50 % of the active sensing surface covered. Full calibration procedure:

• Connect teach wire to V+ for 2 - 7 seconds
• The green LED flashes 1 imp. per sec. and the yellow LED is OFF
• After successful calibration, the yellow LED flashes 3 times (with 1 Hz) Calibration Empty: The sensor switch point is set above the actual detection value to ensure that slight changes in the application will not affect the sensing performance. In most applications, the Empty calibration on an empty tank or tube will be sufficient. In critical applications with a high amount of residue film, moisture or foam build-up, an Empty calibration can be performed with the build-up present. Empty calibration procedure:
• Connect teach wire to V+ for 7 - 12 seconds
• The green LED flashes 1 imp. per sec. and the yellow LED is ON
• After successful calibration, the yellow LED flashes 3 times (with 1 Hz) Cancel calibration procedure:
• Keep the teach wire connected to V+ for more than 14 seconds to abort teach procedure. The switch points will remain unchanged.
• The green LED is off and the yellow LED flashes (4 Hz)
