The precautions for using KLASCHKA sensors are as follows： -
Installation environment requirements
-
Temperature and HumidityIt should be used within the temperature range specified in the manual (usually -10 ℃ to 50 ℃, some models can reach 60 ℃), avoiding damp, water accumulation or direct sunlight environment, and preventing internal components from getting damp or aging.
-
Vibration and CorrosionThe installation location should be free from strong vibrations and kept away from corrosive gases (such as strong acid or alkali environments) to prevent corrosion of the sensor housing or internal components.
-
electromagnetic interferenceAvoid coexisting with strong electromagnetic field equipment such as large motors and transformers. If necessary, use shielded cables or separate wiring pipes to isolate power lines and prevent signal interference.
-
Installation and fixing specifications
-
fixation methodUse specialized brackets or bolts to securely fix the sensor to prevent loosening or displacement caused by vibration. When installing outdoors, it is necessary to install a protective cover to avoid direct rain.
-
Installation locationEnsure that the sensor is aligned with the object being measured, avoiding offset or tilt. For example, proximity switches need to maintain a specified distance from the detected object (magnetic metals can be greater than 1mm, non-magnetic metals need to be adjusted according to thickness).
-
Wiring requirementsSignal cables should use anti-interference shielded wires with a length not exceeding 200 meters (to avoid voltage drop affecting signal quality). The power connection must be made through an insulated transformer, and direct connection to the power supply is prohibited to prevent damage to internal components.
-
Electrical Connection and Compatibility
-
Wiring specificationsStrictly follow the sensor wiring diagram to connect the power supply, signal line, and grounding wire, avoiding polarity reversal (such as SSI signal's Data+/Data - cannot be swapped). Different brands of sensors and magnetic rings cannot be mixed, and compatibility needs to be confirmed in advance.
-
Load matchingThe load current should be greater than 10mA. If it is lower than this value, parallel discharge resistors should be connected to prevent residual voltage from causing poor reset. Avoid connecting multiple sensors in series or parallel, and if necessary, relay them through relays.
-
surge protectionWhen used near equipment that is prone to surge, such as motors and welding machines, surge absorbers (such as nonlinear resistors) need to be installed to prevent damage to internal components.
-
Usage and operation taboos
-
Check before powering onAfter installation, check if the wiring is secure before conducting a power on test. Do not use a multimeter to measure sensor voltage in resistance or current mode to prevent damage to the internal circuit.
-
Prohibit exceeding the rangeAvoid long-term use of sensors beyond their range to prevent measurement distortion or damage. For example, displacement sensors need to reserve a range margin to prevent overtravel usage.
-
Operational SecurityDuring maintenance, the power supply must be cut off, and it is forbidden to plug or unplug the connecting wires when they are live. Non professionals are not allowed to disassemble the fastening screws of the sensor head to prevent internal grounding damage and malfunction.
-
Maintenance and overhaul cycle
-
regular inspectionCheck the fixing status, loose wiring, dust or oil accumulation of sensors every month. Clean the surface dirt of the sensor every quarter and check if the detection distance is normal.
-
Calibration and CalibrationCalibrate every 6 months to 1 year based on usage frequency to ensure measurement accuracy. The flow meter used for trade settlement needs to be calibrated once a year according to the national calibration regulations.
-
Fault handlingWhen abnormalities occur, first check the installation environment, wiring, and load compatibility, and then troubleshoot the sensor itself. For example, when the flow meter displays false measurement, it is necessary to check whether the sensor installation support is firm.
