2. Can the shielded cable of the electromagnetic flowmeter IP68 be connected?
Because it is a shielded cable, it is necessary to ensure the shielding effect of the cable when connected. There are few interference sources on site, and welding should not be a problem. If the site requirements are high or the interference is large, it is best to use the entire cable and not connect it. Electromagnetic flowmeter Shanghai Menghui. Shielded cable is a special type of cable with a mesh braided wire on the outer layer. Cable shielding refers to the outer layer of the mesh braided wire being grounded at one end, which allows external electromagnetic radiation and magnetic field radiation to directly enter the ground without interfering with the inner wires A sophisticated shielded cable has two layers of shielding, the mesh braided wire is designed to prevent magnetic field radiation, and the aluminum foil layer is used to prevent electromagnetic radiation Generally, coaxial cables are used for cable TV, and leads from the frequency converter to the motor are used. In areas with interference, the power supply should also be shielded, and analog leads should also be used Require anti-interference to prevent external electromagnetic fields from entering the circuit. Generally, shielded cables are used for circuits with high frequencies and low signal levels. The most common type is wired coaxial cable, which, in addition to the inner conductor, has a layer of metal mesh on the outside for shielding and is also one of the signal circuits. The core wire of the communication cable, except for the copper conductor, is wrapped with a layer of aluminum foil and grounded to provide shie
3. Do turbine flow meters need maintenance and overhaul?
Every flow measuring instrument requires regular maintenance and repair every year, and turbine flow meters are no exception..
4. How to maintain the turbine flowmeter?
When maintaining a turbine flowmeter, the following points should be noted:
1. When using, the measured medium should be kept clean and free of impurities such as fibers and particles.
.2. When starting to use the turbine flow sensor, the sensor should be slowly filled with medium before opening the outlet valve (which should be installed at the back of the flowmeter). It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a state of no medium.
. The maintenance cycle for turbine flow sensors is generally six months. During maintenance and cleaning, please be careful not to damage the parts inside the measuring chamber, especially the impeller. Please pay attention to the position relationship between the guide components and the impeller during assembly. When the turbine flow sensor is not in use, the internal medium should be cleaned, dried, and protective covers should be added at both ends of the sensor to prevent dust and dirt from entering, and then stored in a dry place.5. The matched filter should be cleaned regularly. When not in use, the internal media should be cleaned. Like the sensor, it sh
