Mine Ventilation Resistance Measurement System Equipment Functions and Performance Requirements:
The mine ventilation resistance measurement system is suitable for mine ventilation resistance measurement, ventilation capacity verification, coal mine gas grade determination, and other tasks. This equipment has the following functions:
2.1 Equipped with pressure test interfaces for easy connection to on-site ventilator static pressure tubes, enabling more accurate and complete ventilation resistance measurements;
2.2 Uses a separate temperature and humidity probe to avoid interference from the instrument and human heat sources;
*2.3 Touch input without a keyboard, intelligent operating system for data processing, user-friendly and simple human-machine interface;
*2.4 Uses a resonant pressure sensor with ultra-high precision and long-term stability, capable of accurately measuring subtle changes in air pressure, suitable for high-humidity underground environments, ensuring the accuracy of key parameters in mine ventilation resistance testing;
*2.5 Provides two measurement modes: base point and measurement point. Base point measurement automatically records data with configurable recording intervals; measurement point mode offers 100 storage areas. Features data storage and data retention during power loss;
2.6 Measures real-time wind speed during wind speed measurement, supports multi-point wind measurement and displays average wind speed, also allows manual input of wind speed measured by other anemometers; fast communication enables synchronous communication with upper computers;
2.7 Comes with specialized test report processing software, automatically pairs measurement point and base point data, and generates compliant test reports.
