Analysis of the factors that may cause the zero point change of the SICK sensor: overload will lead to a sudden change in the zero point, and the output resistance will obviously exceed the specified value impact, as above; Moisture return or turbidity, so it is mainly manifested as a continuous change of 0 point, high and low, etc., at this time, the ground resistance will be further reduced - In the case of no load of the sensor and simulating the use conditions as much as possible, according to the normal connection method of the SICK sensor, a DC voltage of 5-12V is applied at the input end, and the output voltage change is measured with a voltmeter at the output end. The ratio of change to input voltage is converted to millivolts per volt and should not exceed +/- 1% compared to the standard sensitivity in millivolts per volt.
Analysis of the factors that may cause poor insulation of SICK sensors: once the electronic and electrical components of the sensor are wet, the insulation resistance will be reduced, and the electronic components of the sensor will be chemically corroded. First, use a 50V super insulation meter to test the resistance between the elastomer (exposed metal part), the shield wire and the input/output core, and its value should not be less than 5000w. Special care should be taken: never measure input and output resistance with an insulated meter probe; For digital sensors, impedance testing cannot be performed with an insulator.
Analysis of the factors that may cause damage to the bridge due to the SICK sensor: the electrical connection inside the sensor is broken or the short-circuit equipment is burned out - the input and output resistance measured with an ohmmeter can be judged as a fault if there is a significant change compared with the factory inspection value. Factors that can lead to changes in impact resistance: Virtual soldering appears on the electrical connections inside the sensor
The rational selection of sensors for the measurement object and the measurement environment is the first issue to be solved when measuring a certain quantity. Once the sensor is determined, the corresponding measurement method and measuring equipment can also be determined. The success or failure of the measurement results depends to a large extent on the selection of the sensor.

Sick Sensors – Installation Requirements for RTD Sensors
1. In order to have sufficient heat exchange between the measuring end of the RTD and the medium to be measured, the location of the measuring point should be reasonably selected, and the installation of RTD near the valve, elbow, pipe and equipment should be avoided as much as possible.
2. The thermal resistance with a protective sleeve has heat transfer and heat dissipation loss, in order to reduce the ...
