ESM-LK28N reed switch flow sensor

ESM-LK28N reed switch flow sensor
Product introduction:
The magnetic water flow switch uses the magnetic repulsive force of a pair of permanent magnet floats to interact with the impact force of the water flow, and cooperates with the reed switch output switching signal (0/1) to be reset by the repulsive force between the permanent magnets, as opposed to Mechanical springs are more stable and reliable, have a longer service life and have a smaller starting flow.

Precautions:
1. Please read this parameter description carefully before using this water flow switch. If you still have any questions, please consult our technical staff.
2. The structural water flow switch has not been used. It may be inappropriate for direct replacement. Please submit it in time.
3. In the process of installation and use, it is necessary to cooperate with the relay (power is below 3W) to avoid burning the reed switch due to the small switching power. .
4. In order to prevent particles and debris from entering the water flow switch, a filter must be installed at the water inlet.
5. When a magnetic material or a device that generates a magnetic force to a water flow switch is close to a water flow switch, its characteristics may vary.
6. The installation and use environment of the water flow switch should avoid the place with strong vibration and shaking to prevent the water flow switch from malfunctioning.
7. Do not disassemble the water flow switch to prevent damage. Any water flow switch that has been disassembled without authorization is not covered by the warranty.
