The compact tuning fork level switch is a new type of level switch. The instrument consists of a transmitting fork and an amplifier part. Two sets of piezoelectric crystals are pressed at the root of the fork and one group is used as a driver to drive the fork to vibrate. The other group is used as a detector to convert the fork strand into voltage. signal. When the fork strand is blocked, the amplitude of the vibrator becomes smaller, the vibration frequency changes, and the relay outputs the switching signal. In order to achieve the level limit measurement. The sensor is made of 316 stainless steel and is resistant to mild corrosion. It is used for limit controllers and high/low alarms. 
Tuning fork level switch installation and use instructions:
Installation requirements: tuning fork limit switch is usually side mounted (mounted on the side of the warehouse wall) installation and the side wall of the warehouse to detect the upper and lower position of the material level height; when the warehouse body is inconvenient to the side opening can be used when the top loading ( The top of the warehouse should be installed and the location should be selected to avoid the impact of material during the feeding; it can also be installed on the pipeline to prevent the pump from running without material.
Note: 1. When installing the sensor, insert it into the tank and use a wrench to tighten the hexagonal screw on the upper part of the sensor thread. Be careful not to twist the housing by hand because it will cause the shell and probe during the tightening process. Rotation between rods. At the factory, the connecting cable between the electronic unit and the sensor inside the housing is well connected. Tightening the housing by force will cause the internal connection cable to break. 2. Do not apply strong impact to the fork when installing and installing to avoid damage to the piezoelectric crystal. 3. The instrument sensor should try to avoid the impact of the material. In the horizontal installation, the two parallel forks of the fork should be perpendicular to the ground (the direction of the fork at this time is stamped or punched) to ensure that the material can be easily Flow out from between the forks.
Tuning fork level switch product debugging and wiring:
a. The compact tuning fork level switch is an intelligent, debugging-free product. After the power is applied, the relay starts to work 3-5 seconds. The LED lamp starts flashing and the relay is closed. When the fork hits the material, the LED stops blinking and the relay opens. If the LED lamp does not flicker or the flashing can not stop when touching the fork, consult the manufacturer.
