RST1 Torque Sensor

Torque is the rotational equivalent of a linear force. Just as an applied force is a push or pull that seeks to move an object in a linear direction, torque is a "twist" force applied that tries to "turn" or rotate the object to which it is applied. When your car wheels turn the engine is applying a Torque. When you try to open a pasta sauce bottle cap, you are applying a Torque. Our RST1 Torque Sensors help you measure twisting forces being applied or being experienced by an object up to 150 Nm range. 

You can buy just the torque sensor or buy the torque sensors with interface devices such as analog signal conditioners, digital USB or wireless interfaces, and software as complete ready to use kits.

  • Construction and Use
    Made of Aluminum with threaded mounting holes on each end for ease of mounting

  • UART/USB Output
    Use DI-1000U with USB output to connect with PCs, Macs, or Linux machines.

    Wireless Output
    Wireless output via XBee (802.15.4) or WiFi or BLE.

    Analog Output
    Analog output via 0-5V DC or 4-20 mA for easy input to DAQ/PLC

    Customize
    Call us for larger capacities or other unique needs. We can custom build them to order as needed.

Mounting Options

The RST1 torque sensors have threaded holes on each end to mount them to mating surfaces easily. The sensors can be mounted in any orientation. Does not need to be verically mounted. The measured torque will be the relative rotational force applied between the two ends of the torque sensor.

Torque Sensor Configurations

Torque Sensors are similar to resistive Load Cells which are based on the classic wheatstone balanced bridge network design using strain gages. The baseline output is mV/V i.e. if you supply say 10V to the sensor, then the output voltage may vary from 0 mV to 20 mV for a 2 mV/V device. They can be mated and used with digital or analog signal conditioners (digital or analog interfaces) to connect with PCs, PLCs, or simple LCD diplays. We offer the following options:

Torque Sensor with DI-1000U Configuration

If you need to do testing and data gathering or want to display values on a PC/Tablet via USB, simply connect the Torque Sensor to the DI-1000U USB Sensor Interface & use the USB connector on the DI-1000 to connect to a PC via the USB port. The DI-1000U is a signal conditioner & 24-bit digitizer (good enough to handle devices with 0.02% of full scale accuracy) and handles all the communications functions to talk with USB port of a PC.  When connected this way, the torque sensor appears on the PC as a virtual COM port. Using a standard terminal emulator you can send commands to the sensor to display loads on screen. They can be displayed either one reading at a time or in continuous operation mode. You can also use Matlab, LabView or other popular programs to communicate and get calibrated readings from the torque sensor. It would be best if used with our SensorVUE application to display, log or plot data on a Win 8/10 PC or Tablet.

Wireless Torque Sensor Configuration

You can use these Torque Sensor wirelessly by connecting it to our DI-1000ZP wireless sensor interface. This configuration allows you to wirelessly connect to a Windows/Unix/Mac computer. On a Windows 8/10 PC or Tablet, you can use our SensorVUE software to display, log and plot force vs time data effortlessly. The DI-1000ZP uses the 802.15.4 protocol and offers robust connectivity to about 1000 feet in industrial environments. It comes with a battery backup for cordless operation for a couple of hours. If you wish to connect via WiFi or BLE we offer the DI-1000WiFi and DI-1000BLE that makes it easy to communicate with SmartPhones as well.

Analog Torque Sensor Configuration

Some users want a high level 0-5V analog DC output in order to work with existing data acquisition systems or PLCs. Ih that case, you can use this torque sensor with our AI-1000 signal conditioner which provides an amplified 0.5 to 4.5V output proportional to the applied torques. We can provide the system together with calibration and the formula to convert from voltage to torques when ordered in this configuration. We also offer the AI-1000-CV with 4-20 mA output if you prefer current output. Please contact us for this kit.

Application Development

If you are looking to develop your own custom software application, our digital sensor interfaces offer convenient ASCII commands to obtain load information directly from the interfaces without need for any additional signal conditioning or data processing. With just a few commands you'll be able to incorporate calibrated sensor information into your application. You can also use Visual Basic, Visual C++, Matlab, LABView or any other application development environment to create your custom applications with our interfaces and sensors.
