Safety Calibration Process for Low-Concentration Infrared Methane Sensors and Wind Speed Sensors in Coal Mines

Safety Calibration Process for Low-Concentration Infrared Methane Sensors and Wind Speed Sensors in Coal Mines

1. Calibration of “Zero Position”After preheating the sensor for 20 minutes, connect the sensor gas chamber to the air sample bag using a rubber hose → Use the remote control to set the sensor to the “zero display interface” → Open the calibration gas sample bag, adjust the flow meter to the flow and ventilation … Read more

Overview of Types and Working Principles of Wind Speed Sensors

Daily Proverb Life has its limits, but knowledge is limitless. Overview of Types and Working Principles of Wind Speed Sensors 1. Mechanical Wind Speed Sensor The wind force generated by air flow drives the sensor to rotate, with the central axis driving internal sensing elements to produce pulse signals. Within the wind speed measurement range, … Read more
