In the demanding world of mining, hydraulic support control systems stand as pivotal equipment for production. These systems, equipped with microcontrollers, pressure transmitters, and other electronic devices, along with hydraulic circuit control components, automate the operations of the hydraulic support framework as needed. Among these components, pressure transmitters play a crucial role by monitoring the pressure values of the front and rear supports as well as the front beams of the hydraulic supports.
Optimal Performance and Long-Term Stability
For effective operation, pressure transmitters must exhibit excellent performance and long-term stability. These attributes are essential for ensuring the safety of the entire system and the mining process. Zero Instrument Pressure Transmitters, with a range from -100 kPa to 0 to 100 MPa, can measure a wide range of pressures, making them suitable for the diverse conditions encountered in mining operations. They are available in precision grades of 0.1% FS, 0.25% FS, 0.5% FS, and 1% FS, allowing for flexibility depending on the application’s accuracy requirements.
Robust Specifications
Zero Instrument Pressure Transmitters operate within a medium temperature range of -40 to 85°C and a similar environmental temperature range. Their seismic performance is rated at 10g, with a response frequency of ≤500 Hz for analog signals and ≤5 Hz for digital signals. The stability of the transmitters is maintained within ±0.1% FS per year. These specifications highlight the transmitter’s high precision, excellent stability, fast response time, and impact resistance, which are crucial in the harsh underground mining environments.
Transformation in Mining Operations
Traditionally, due to less advanced industrial production levels, hydraulic supports in China were mostly manually operated. Although manual hydraulic supports were cost-effective and simple to operate, they were slow to move and had low production efficiency. Moreover, the severe conditions underground made manual operations prone to accidents. Today, with the adoption of pressure transmitters, automated hydraulic support control systems have become operational, ensuring normal, efficient, and safe production processes in mining.
Conclusion
The integration of pressure transmitters in mining industries is indispensable. Their ability to provide precise and stable pressure measurements enhances the automation and safety of hydraulic support systems, transforming mining operations from manual to automated, high-efficiency processes. This technological evolution marks a significant advancement in ensuring safer and more productive mining operations.
