Water Level TV Monitoring System
Model : HLTV-200A
Brand : CHANGCHUN BOILER INSTRUMENT
Product Overview
The HLTV-200A, B, and C fully digital water level television monitoring systems are primarily used for monitoring the water level of boiler drums in thermal power generators. They can also be used for short-range and long-range monitoring of fixed or moving targets in production, scientific research, construction, and dispatching operations, even under harsh conditions such as high temperatures below 80°C, high radiation levels, and high dust levels. The system provides direct monitoring of on-site targets with high reliability and security. It provides real-time, vivid, and accurate images of monitored objects, making it an extremely effective observation tool in modern management.
Working principle:
The system transmits the monitoring signal of the monitored target to the monitor through an analog camera or a digital network camera, and then the monitor restores it into an image for target monitoring.
The operator can adjust the camera lens and electric pan/tilt (optional, standard is semi-fixed pan/tilt) in the control room through the controller or DCS operation station (DCS outputs several normally open passive dry contacts to the controller) to clearly monitor all angles of the target scene.
The HLTV-200A/2 is a high-reliability digital water level TV monitoring system designed for real-time visual surveillance of boiler drum water levels. It’s engineered for harsh environments—high temperature, radiation, and dust—and is widely used in thermal power generation, chemical plants, and metallurgical operations.
