Brief introduction The instrument is a special type of tunnel, the detection probe installed on the wall of the tunnel, the tunnel total control room to provide wind speed, wind direction detection value, as the basic basis for ventilation and operation. The detector can be field instrument for real-time observation of running status and detection data, and data output interface analog and switch quantity signal can nearby access control indoor PLC, through the data optical transmitter and optical fiber access control room. Technical parameter Measuring principle: Ultrasonic Technology Installation: tunnel side wall Measuring range: wind speed -30 M / s to 30 m / s: positive and negative direction Measurement accuracy: wind speed of 0.1 M / S. The average time: 0.1 seconds to 60 minutes adjustable Analog output: 2 x 4 ~ 20mA current output isolation, maximum load impedance of 500 ohm Switch output: 2 passive relay output Digital interface: RS232, RS485 Supply voltage: 220VAC + 10%, 50Hz/60Hz Ambient temperature: -50 to +75 C. Protection grade: IP67
