As an upgraded variant in the DH-S product family, the DH-S-3BB represents the third-generation non-contact speed monitoring solution for industrial conveyors. Unlike traditional mechanical sensors, this system employs advanced photoelectric measurement technology capable of detecting belt speeds ranging from 0.05m/s to 9.99m/s with ±0.5% accuracy.
Proper installation significantly impacts measurement accuracy. Our field tests show that mounting the sensor 15-20cm below the return belt surface reduces material interference by 78% compared to traditional side installations. Two recommended configurations:
The self-diagnostic function automatically detects lens contamination, triggering an alert when transparency drops below 60%. Annual recalibration using the built-in reference wheel maintains ±0.2% long-term accuracy – crucial for mining operations where 1% speed variation can cause 15-ton/hour throughput fluctuations.
In a recent iron ore processing plant retrofit, implementing DH-S-3BB reduced emergency停机时间 by 42% through predictive maintenance alerts. The system's vibration compensation feature proved particularly valuable in screening plant environments with 5-7mm/s² vibration levels.
