| HY-3SF reverse speed monitoring and protection instrument is an intelligent monitoring instrument designed for rotating machinery. It uses ARM as the core and has functions such as speed monitoring, dual alarm setting points, and analog current output. It can simultaneously receive two LH520 gear speed sensor signals or two signals from a LH530 gear reverse speed sensor, and is used to continuously monitor and measure the speed of rotating mechanical devices. At the same time, it can measure the rotation direction of the shaft and provide alarm and protection signals when the equipment reverses. This product is suitable for multiple industrial fields such as electricity, machinery, chemical industry, and metallurgy, providing multiple parameter measurements and early fault prediction for the operation of rotating machinery. |
| Technical Specification: Input signal: speed sensor or reverse speed sensor signal Range: 1-99999rpm Display: five-digit 0.8-inch LED digital display Display accuracy: 1rpm Number of teeth: 1-255 arbitrary Current output: 4-20mA active, output load ≤500Ω Alarm point setting: 0-100% full scale Alarm relay: node capacity 7A/250VAC Working power supply: AC220V±10% 50Hz±5% Temperature range: -20ºC to +65ºC Relative humidity: ≤95% Use environment: no corrosive surroundings, no strong magnetic field, etc. |
| Product features: Parameters can be set by buttons, easy to operate. Dual alarm settings. Reverse protection, effectively preventing damage to the machine due to sudden accidents. High-precision measurement, ensuring the accuracy and reliability of measurement results. Strong anti-interference ability, able to operate stably in harsh industrial environments. Multiple output modes, can be connected to computers, DCS, PLC systems, paperless recorders and other equipment to achieve remote monitoring and data recording. |
| Application: HY-3SF forward and reverse speed monitoring and protection device is widely used in rotating mechanical devices in the power, machinery, chemical, metallurgy and other industries, such as steam turbines, coal mills, fans, reducers, water pumps, centrifuges, balancing machines, air compressors, etc. |
