The components of the wireless sensor are packaged in a shell and powered by a battery or vibration generator during operation, forming a wireless sensor network node that is widely used in multiple fields. What types of wireless torque sensors are there?
The node has a compact structure and is packaged in a resin shell. Each channel of the node has a high-precision 120-1000Ω bridge resistance and amplification conditioning circuit. The bridge is automatically balanced. The air transmission rate of the torque sensor node in the wireless torque sensor can reach 250KBPS, and the effective real-time data transmission rate can reach 4KSPS. The effective indoor communication distance can reach 100 meters. For long-term monitoring applications, the torque value is sent once every 5 minutes, and the battery does not need to be replaced for several years, greatly improving the system's maintenance-free nature.
The sampling rate of each node can be set to 4KHz, and each channel is equipped with an anti-aliasing low-pass filter. The collected data can be wirelessly transmitted to a computer in real-time or stored in the 2M data storage device built into the node to ensure the accuracy of the collected data. The effective outdoor communication distance can reach 300m, the node power consumption is only 30mA, and using a built-in rechargeable battery can continuously measure for 18 hours. If you select a node with a USB interface, you can charge the node via the USB interface or quickly download the data stored in the memory to the computer.
The node has a compact structure and is packaged in a PPS plastic shell consisting of a power module, a collection and processing module, and a wireless receiving and transmitting module. Each channel of the node has an independent high-precision 120,1000Ω bridge resistance and amplification conditioning circuit, and can be conveniently switched between 1/4 bridge, half-bridge, and full-bridge measuring methods using software. Compatible with various types of bridge sensors such as strain, load, torque, displacement, acceleration, pressure, temperature, etc. The node supports both 2-wire and 3-wire input methods, and the bridge is automatically balanced. It can also be stored in a 2M data storage device built into the node. The effective outdoor communication distance can reach 300 meters. It can continuously measure for more than ten hours.
The wireless torque sensor node is easy to use. You only need to fix the sensor node, battery, and strain piece on the rotating shaft to measure the strain value of the rotating shaft and wirelessly transmit it to the gateway or routing node in real-time. Use the strain torque conversion formula in the collection control software to calculate the torque value. For long-term monitoring applications, the conversion algorithm can also be embedded in the node to directly transmit the torque value.
The wireless torque sensor node greatly saves the human and material resources consumed by repeated deployment of wired data acquisition equipment in testing. The wireless digital signal transmission method eliminates noise interference caused by long cable transmission and collecting rings. The entire measurement system has high measurement accuracy and anti-interference ability. Wireless sensor nodes can form a large wireless sensor network and support simultaneous measurement of thousands of measuring points.
