Product Introduction
1. Wireless Torque Sensor TQ201 Product Description:
Wireless Torque SensorThe node is simple and convenient to use. Simply fix the sensor node, battery, and strain gauge on the rotating shaft, directly measure the strain value of the rotating shaft, and transmit it wirelessly in real time to the gateway or routing node. Use the strain-torque conversion formula in the acquisition control software to calculate the torque value. For long-term monitoring applications, conversion algorithms can also be embedded in the node to directly transmit torque values. The wireless torque sensor node greatly saves manpower and material resources consumed by repeated wired data acquisition equipment setup during testing. The wireless digital signal transmission eliminates noise interference caused by long cable transmission and slip rings, and the entire measurement system has extremely high measurement accuracy and anti-interference capability. Wireless sensor nodes can form a large wireless sensor network, supporting simultaneous measurement of thousands of measurement points. It is widely used in torque, power measurement, and online monitoring of industrial rotating machinery.
The node has a compact structure, small size, and is encapsulated in a resin housing. Each channel of the node has a built-in high-precision 120-1000Ω bridge resistance and amplification conditioning circuit, allowing easy software automatic switching between 1/4 bridge, half bridge, and full bridge measurement modes. The node also supports 2-wire and 3-wire input modes with automatic bridge balancing. The node's over-the-air transmission rate can reach 250 Kbps, with an effective real-time data transmission rate of 4K SPS, and an effective indoor communication distance of up to 100 meters. The node is designed with dedicated power management software and hardware. Under real-time continuous transmission, the node consumes only 25mA, and with a standard 9V battery, it can measure continuously for dozens of hours. For long-term monitoring applications, sending torque values once every 5 minutes, the battery can last for several years without replacement, greatly improving the system's maintenance-free performance.
