Presence Detection of Solid Objects Point-Level Detection through Container Walls
Flush (shielded) Sensors These capacitive sensors use a larger spherical electrical which is especially suited as level detectors Non-Flush (unshielded) Sensors for liquids, granulates or powders.
Direct Point-Level detection
Flush mountable sensors are normally being used for presence detection of objects or for indirect point level detection of solids, powders or liquids. The following two setup routines help to assure proper setup and operations. All BCS sensors allow sensitivity adjustment potentiometer.
The following procedures are outlined for setting a normally open capacitive sensor for ideal sensing conditions: 1. Mount the sensor in the actual sensing position 2. Set up the target for the worst case condition. This means for a presence detection application to move the object to the farthest occurring position from the sensor. 3. All BCS capacitive sensors are already factory preset to their maximum operational sensing range. The sensor has to move closer to the target object, if the farthest object position does not assure a reliable switching. Alternatively, a larger sensor with a larger sensing range can be chosen. 4. The sensitivity can now be reduced by turning the potentiometer CCW until the sensor switches off. Increase now the sensitivity CW by 1/2 turn to set the sensor to its optimal sensitivity setting. Example: In the following example, a shielded capacitive sensor in a M12 tubular housing will be used to detect a ceramic plate. The sensor is factory preset to a maximum rated switching distance sn of 4 mm to metal or by approximation to your hand. When moving the sensor towards the target object, the rated switching distance sn to the ceramic plate has been reduced to approx. 2mm. This distance is now the maximum permissible switching distance for the ceramic plate. To ensure that Balluff's BCS capacitive sensors work reliably within their technical specifications, they have a greater sensing distance than the indicated maximum rated switching distance sn in the datasheet. If the user decides to adjust the sensor to a switching distance greater than 2mm for the above described ceramic plate, the sensor will operate in an unreliable mode. This entails a risk that temperature and other environmental factors or electrical interferences may lead to unreliable switching conditions. Note: 1. Mount the sensor in the actual level sensing position flush to the non-metallic container wall. 2. All BCS capacitive sensors are already factory preset to their maximum operational sensing range. The sensor will initially trigger on the container wall material. 3. The sensitivity has to be reduced by turning the potentiometer CCW until the sensor switches off. Increase now the sensitivity CW by 1/2 turn to set the sensor to its optimal sensitivity setting. 4. The sensor should switch on at 40% to 50% sensing area coverage - readjust the sensitivity CCW if the coverage is above 50% and CW if it is below 40%. 1.
