ZPW-3.7RC Intrinsically Safe Wireless Pyroelectric Touch Sensor for Mine-Use Automatic Spray Dust Suppression System
Person and vehicle detection system for underground mine roadway areas
Classification:
Instruments and Meters
Product description
Product Overview
● Integrating infrared pyroelectric sensors and touch sensors into one, this device is ideal for detecting people and vehicles in underground mine roadways. When a person or vehicle enters the detection area, the sensor outputs a high-level signal; however, when no vehicle is present, it generates a low-level signal as the vehicle passes through.
● The touch control uses vibration-sensing probe technology: when coal is present on the conveyor belt, the sensor outputs a high-level signal; when no coal is detected, it outputs a low-level signal.
● Equipped with a 2.5AH rechargeable lithium battery, it can operate continuously for over 18 months without the need for an external power source or cables.
● The communication system utilizes the L0RA wireless transmission module, offering long-range connectivity while ensuring precise, efficient, and hassle-free integration between sensors, the main unit, and remote stations.
