TH-SQX1型隧道风速风向检测设备为隧道应用型，检测探头安装在隧道墙壁上，为隧道总控室提供隧道内风速、风向检测值，作为通风和营运的基本依据。检测器可以现场实时观测仪器运行状态及检测数据，同时数据输出接口输出的模拟和开关量信号可接入附近的分控室内地PLC，再通过数据光端机和光纤接入总控室。

主要特点：

1.铸铝机身，表面阳化处理，适应隧道内恶劣的环境

2.采样区横跨隧道内行车道，更真实反应隧道内气体流速

3.采用超声波检测原理，不受环境温度影响

4.非接触式检测，内部没有活动部件，减少故障率

安装方式：

根据联合设计图纸的要求，直接安装在隧道壁上，以隧道车行方向，隧道壁右侧，3～4米高度。传输信号线缆使用2根双绞屏蔽线或RVVP4*0.3。

The TH-SQX1 tunnel ultrasonic wind speed ａnd direction detector is a tunnel application type. The detection probe is installed on the tunnel wall to provide wind speed ａnd direction detection values inside the tunnel for the main control room, serving as the basic basis for ventilation ａnd operation. The detector can observe the real-time operation status ａnd detection data of the instrument on site. At the same time, the analog ａnd switch signals output by the data output interface can be connected to the nearby PLC in the sub control room, ａnd then connected to the main control room through data optical transceiver ａnd fiber optic.

Main features:

1. Cast aluminum body, surface anodized treatment, suitable for harsh environments inside tunnels

2. The sampling area spans the inner lane of the tunnel, providing a more realistic reflection of the gas flow velocity inside the tunnel

3. Adopting the principle of ultrasonic testing, unaffected by environmental temperature

4. Non contact detection, with no moving parts inside, reduces failure rate

Installation method:

According to the requirements of the joint design drawings, it should be installed directly on the tunnel wall, in the direction of tunnel traffic, on the right side of the tunnel wall, at a height of 3-4 meters. The transmission signal cable uses 2 twisted pair shielded wires or RVVP4 * 0.3.
