Magnetic flap level gauge alarm switch selection instructions

The choice of the alarm switch of the magnetic flap level gauge: a remote transmission method of the magnetic flap level gauge is to be equipped with an alarm switch. The liquid level control switch is composed of a dry reed switch and a circuit module, which is compact and durable. According to the purpose, it can be divided into ordinary liquid level control switch, with holding (memory) type liquid level control switch and high temperature belt holding (memory) type control switch. The liquid level control switch is fixed on the outside of the UHZ magnetic flap liquid level gauge in a bundled form, so that it is in the same magnetic field system of the liquid level gauge. When the magnetic float moves up and down with the liquid level, the corresponding liquid level position has a dry reed The tube is attracted by the magnetic field in the float, and the changed signal is converted into a passive switch signal output by the conversion module, and it is not released until the return induction signal arrives. Therefore, it can be conveniently used with various instruments to achieve control and alarm. Got sight. Installation matters of the magnetic flap level gauge: 1. When the magnetic flap level gauge is installed and selected at the beginning, you should pay attention to avoid selecting the outlet or inlet far away from the material, so as to prevent the material fluid from becoming violent in its own local area. 2. When equipped with a remote transmission instrument, you need to pay attention to the following: 1) The zero point of the remote transmission instrument should be on the same level as the zero point indication of the liquid level meter. , 2), the connection between the remote transmission supporting instrument and the display instrument or industrial computer should preferably be laid through a protective tube or a shielded two-core cable; 3), the remote transmission supporting instrument should be close to the liquid level gauge winner. 4) The sensing surface of the remote transmission supporting instrument should face and close to the main duct; 5) After the junction box inlet hole is laid, it is required to be well sealed to avoid rain and moisture. If the remote transmission instrument cannot work normally due to intrusion, the junction box should be covered and covered in time after the inspection and debugging is completed. In addition to the addition of a switch alarm method to the magnetic flap level gauge, the externally attached liquid level switch is a commonly used non-contact liquid level switch. It does not need to contact the measured medium. The measuring probe can be attached to the outer wall of the storage tank to realize the liquid Bit high and low alarm. Safe and convenient.
