The TRH-K-Y01 tuning fork type liquid level controller is a general-purpose liquid level switch. The tuning fork is excited by the piezoelectric crystal to generate vibration. When the liquid level controller is immersed by liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switch quantity to achieve the purpose of alarm or control of the liquid level controller. The structure and principle characteristics of the liquid level controller make it able to replace the liquid level switch of any mechanism. It is widely used in the petrochemical, metallurgy, light industry, building materials and other industries to raise and control the upper/lower limit of the liquid level.


main feature


Adaptability - The electrical parameters and density of the tested materials have no effect on the measurement. Severe conditions such as fouling, agitation, turbulence, air bubbles, vibration, moderate viscosity, high temperature, high pressure, etc. have no effect on the detection.

Free of maintenance – Since the detection process of the tuning fork limit switch is completed by electronic circuits and has no moving parts, maintenance is not required once installed and put into operation.

No adjustment is required – since the detection of the tuning fork limit switch is not affected by the electrical parameters and density of the measured medium, no on-site adjustment is required regardless of the liquid being measured.

. The meter consists of a signal sensor and an amplifier section that compresses two sets of piezoelectric crystals at the root, one as a driver that drives the inductor to generate vibration and the other as a detector to convert the prongs into a voltage signal. When the sensor is blocked, the amplitude of the vibrator becomes smaller, the vibration frequency changes, and the relay outputs a switching signal. Thereby the level limit measurement is realized. The sensor is made of 316 stainless steel and is resistant to mild corrosion for limit controllers and high/low alarms.

2, the working principle

     The working principle of the liquid level switch vibrator is based on whether the material has resistance to the tuning fork in the vibration, and whether the material level reaches or exceeds a certain height, and an on-off signal is issued. The tuning fork of the sensor vibrates at an inherent frequency. When the sensor touches liquid or other materials, its inherent vibration frequency is reduced. The energy consumption is on the friction between the material particles, forcing the amplitude to abruptly attenuate and stop the vibration. The frequency change activates the liquid level. The switch generates an on/off signal.
