Tuning fork level switch is a liquid level detection instrument designed with tuning fork principle. It is suitable for liquid level measurement in containers, storage tanks, tanks and pipelines. In industrial production, the tuning fork level switch has many applications in an explosive environment, so the company provided an explosion-proof tuning fork level switch for the user to choose. There are two types of explosion-proof tuning fork level switches, which are classified into explosion-proof type and intrinsically safe type (referred to as intrinsically safe type). Flameproof tuning fork level switch is mainly used to seal the electrical components with a metal shell to prevent the ignition source from contact with dangerous gases. The intrinsically safe tuning fork level switch is mainly used to limit the energy in the electrical circuit and cooperate with the structural design of the electrical equipment, so that the electrical circuit can not produce the energy required to reach the ignition source. Explosion-proof tuning fork level switch In addition to observing the general tuning fork level switch installation precautions (see the tuning fork level switch installation drawings and installation precautions), due to the difference of the above explosion-proof forms, the installation precautions of the explosion-proof tuning fork level switch are also different: Dry Type Special Transformer,Voltage Variable Frequency Transformer,Power Transformers,Moisture Resistance Transformer SANON DOTRANSÂ Co., Ltd. , https://www.sntctransformer.com
For the explosion-proof instrument, the shell is the most important protection barrier, and the installation should pay attention to: 1 can not damage or change the instrument shell structure, such as drilling, grinding, knocking. 2 When installing, pay attention to the accuracy of the sealing surface of the housing. Do not sand or bump the sealing threads of the upper and lower housings. 3 Cable protection joints should be explosion-proof joints, and the sealing band must not be exposed. 4 The instrument is reliably grounded and must be used within a reliable temperature range.
For intrinsically safe instruments, the main purpose is to limit the energy of the electrical circuit. During installation, care should be taken to: 1 Install the relevant equipment of the specified model and ground it reliably. 2 Pay attention to the line length of the instrument. It is required that the distributed capacitance and distributed inductance of the line should not exceed the maximum allowable value specified by the meter. 3 pay attention to the use of environmental requirements and power requirements, do not use ultra-temperature over-temperature.
Counting Ring-11 tuning fork level switch is a highly reliable compact type dedicated control switch for level measurement. The tuning fork length is only 40mm, not only suitable for level measurement in containers, tanks, tanks, but also for the level measurement of the catheter. It is widely used in liquid level measurement such as hydrochloric acid, sulfuric acid, nitric acid, lye, industrial wastewater, syrup, liquid medicine, etc., and is especially suitable for complex measurement occasions with bubbles, bubbles, viscous liquids and vibration interference. Because Ring-11 tuning fork liquid level switch passed the intrinsically safe and flameproof dual explosion-proof certification (Exxia IIC T6, explosion-proof Exd IIC T6), it is an ideal choice for liquid level control in the petrochemical industry.
