1 product overview

The ZY-ZC heavy hammer level gauge is controlled by a single-chip microcomputer, which has strong functions and easy operation. It solves the problems of traditional heavy hammer level gauges such as easy winding of ropes, easy burial of hammers, and easy loss of hammers. It is particularly suitable for level detection and control of powder and block particles in cylindrical silos in industries such as cement, metallurgy, coal, chemical, feed, docks, and grain. Application: Measurement of powdery, granular, and block solid materials, coal plants, power plants, and steel mills Product technical specifications Measurement range: 0-8 meters, 0-16 meters, 0-32 meters (special specifications can be negotiated) Measurement accuracy: ± 1% Resolution: ± 3cmDetection speed: 0.15m/s Measurement strip: Stainless steel wire rope Heavy hammer Weight: 1kg Motor stopping torque: 5N. m Power consumption: 0W when stationary 40W when running Environmental temperature: -40 ℃~+60 ℃ Weight: 30kg Power supply voltage: 220VAC ± 10% 50Hz ± 1Hz Power consumption: 15W when stationary 55W Environmental temperature: 30 ℃~+60 ℃ Digital display: 0.00~20.50 (meters) Current output: 4~20mA Accuracy: ± 1% Timing time: 15~130 minutes (or according to user requirements) Distance from sensor: 0.5km Weight: 5kg Dimensions: Width 88 × Height 159 × Length 503 Hole size: Width (77+1) × Height (153+1) ■ III. The sentence is: The working principle of the product is that the heavy hammer level gauge is installed at the top of the silo, and the detection process of the level gauge sensor is controlled by the signal sent by the control display instrument. The sensor consists of a reversible motor, worm gear, worm gear, lead screw, gear shaft, winding drum, sensitive lever, etc. When the sensor receives a detection command: the motor rotates forward, and after being reduced by the worm gear and worm, it drives the gear shaft and the winding drum to rotate, lowering the steel wire rope and driving the heavy hammer to descend from the top of the warehouse. When the heavy hammer descends to the material surface and is lifted by the material surface, it loses weight. The steel wire rope trips, and the sensitive lever action makes the micro switch contact. The control display immediately sends a motor reverse command when it receives this signal. The heavy hammer rises and returns until the winding drum touches the top switch, and the motor stops rotating. The heavy hammer returns to its original position at the top of the warehouse, completing a detection process. During this process, the control display instrument calculates the distance between the heavy hammer and the material surface by detecting the number of revolutions of the winding drum, displays it digitally on the panel, and outputs a 4-20mA current on the rear panel terminal.
