Gate opening/height gauge WTG-AS

1. Product Introduction​

​WTG-AS gate opening (height) meter​
The dedicated automatic measurement and control equipment developed by Weite is used forPrecise measurement, display and controlThe opening degree of the gates of equipment such as hoists, gantry cranes and cranes. The system consists ofMain control machine​ + ​High encoderIt is composed and connected through a dedicated shielded cable.

​Core valueAddress the real-time monitoring requirements for gate position data in water conservancy and hydropower projects.

WTG-AS andWTM-AS gate opening load meterSimilar, but with functional differences, the former only has the function of measuring height, while the latter can measure both height and weight.

​2. Main functions​

​Multi-parameter collaborative monitoring and intelligent protection​

• ​Precise monitoring of opening degree​：
  • ​Height valueReal-time display of 0-99.99 meters of opening (accuracy ±1cm)
• ​Multiple safety controls​：
  • ≤7 independent outputs (switch quantity /RS485/4-20mA)
  • Automatically cut off the power at the preset limit position (such as when the height is too high)
• ​Intelligent operation and maintenance guarantee​：
  • Power-off memory + power failure protection function
  • Anti-interference jitter delay algorithm

​3. Scope of application​

​General-purpose equipment for harsh working conditions​

• ​Applicable equipmentWater conservancy gate hoist, portal crane, bridge ship unloader
• ​Applicable scenarios​：
  • Control of gate opening in hydropower stations
  • Port gantry crane unloading height management
• ​Adaptation conditionsAmbient temperature: -20℃ to +60℃; humidity: ≤90%RH

4. Core advantages​

​The three major competitive advantages of water conservancy project verification​

​✅ monitoring accuracy​

• Dual digital tube split-screen display (0.01 meter level accuracy)
• The measured error of hydropower stations in multiple river basins is less than ±1cm (such as the Three Gorges Hydropower Station and the SK Hydropower Station in Pakistan, etc.)

​✅ ease of use​

• Embedded installation design (compatible with 160×80mm electrical control cabinet openings)
• The on-site adjustable limit point supports flexible deployment by wall-mounted or bracket mounting

​✅ operational reliability​

• IP54 protection, strong anti-interference ability
• After 2,000 hours of aging test, the lifespan exceeds 10 years

​6. Practical cases​

​The reliability of global hydropower station verification​

​Case 1: Three Gorges Hydropower Station​

• ​ChallengeThe synchronization of the opening degree of the giant gate requires a small error
• ​"Plan"Multiple sets of WTG-AS systems are linked for control
• ​"Outcome​：
  • There were no faults in N consecutive take-offs and landings
  • The opening degree control accuracy of the flood discharge gate is high

​Case 2: SK Hydropower Station in Pakistan​

• ​ChallengeHigh-temperature and high-humidity environment
• ​"Plan"WTG-AS customized three-proof version
• ​"Outcome​：
  • Has been running stably for many years
  • The ability to resist electromagnetic interference has been enhanced
