1. After the wireless sensor is installed, batches appear to show jitters or inaccurate figures. Reasons: There is electromagnetic interference on the spot, or the signal cable and power line are in the same slot.
Solution: The performance of the product selected by the customer does not meet the on-site conditions. The transmitter with isolation function must be installed or replaced.
2. Wrong or not displayed on the wireless sensor installation Cause: The wiring of the positive and negative levels of the signal line is wrong. Solution: Disconnect the power supply, exchange the positions of the two signal lines, and use the terminals to compress and re-power on. In particular, the PT100 RTD sensor with three-wire output without a transmitter often causes such problems when installed on site.
3. The value displayed after the use of the wireless liquid level sensor is unchanged. Cause: The water intake solution in the air pipe is returned to the factory for maintenance. The air in the air pipe is drained, and the calibration is performed again.
4, the temperature sensor no signal output reasons: workers installed, because they do not understand the sensor, so the force is too large, resulting in the pull-out of the temperature measuring element pins, so that the signal loop interrupted.
Solution: When installing, just connect the wire to the terminal, without removing the transmitter or magnetic board, use the terminal to compress the signal lead.
5, intelligent control instrument installation does not show the reasons: instrument parameter settings are not correct solution: first confirm the type of signal received by the wireless sensor, corresponding to this type of intelligent control instrument input parameters can be adjusted.
