Industrial Grade Wireless CAN bus Multi-Sensor Strain Gauges

$595.00

Breakthrough technology uses CAN bus to “daisy chain” multiple small strain gauge sensor modules to one wireless Leap transceiver node. Anywhere from 1 to 16 strain gauge modules can be added to the bus. Each CAN strain module can support 2 full-bridge resistive strain gauge sensors, for a total of up to 32 full-bridge strain gauges per transceiver node.

Edge processing at the strain sensor level assures a high-quality conversion of the sensor voltage reading to a digital reading, which can then be reliably sent via the CAN bus to the wireless transceiver node.

Industrial CAN bus cables can be over 600 feet long.

Ideal for wireless monitoring of strain in multiple points along structural components such as I-beams, girders, hanging structures, support columns, railways etc., as well as industrial applications such as rotating shafts in engines, turbines, etc.

CAN bus Strain Gauge Module Specifications

  • 2 full-bridge strain sensors may be connected to each module.
  • Up to 16 modules may be daisy-chained to the industrial CAN cable that connects to the transceiver node.
  • Modules are rugged – IP67, powder-coated aluminum with IP67 glands and connectors.
  • Each module has a cable-in and cable-out M8 connection. The last module needs a terminating connector.
  • Strain sensors are connected to terminal blocks inside the module. The strain sensor cables exit through IP68 metal cable glands.
  • Axial, bending, or torsional strain may be monitored depending on how the strain sensor is connected to the terminal block inside the module
  • The strain sensing circuit is inside each module: excitation voltage, amplifier, 24-bit A/D.

Wireless Strain Sensor Specifications

  • The Leap wireless sensor electronics can be integrated with a wide range of strain sensors:
    • Using a full-bridge, the sensors measure axial strain only.
    • Full bridge (standard for axial-only measurement), half bridge, and quarter bridge.
    • 120 ohm, 350 ohm, and 1000 ohm.
    • Gage factor (2.0) standard.  Other gage factors also available.
    • Spot-weld-on (most common), foil, silicon…  Contact us for advice on applying strain gauges.
  • Most wireless strain sensors are tailored to specific needs. Contact us to integrate an application-specific strain sensor with the Leap Sensors wireless system.
  • Over-the-air wireless zeroing to compensate for installation residual strain.
  • Standard strain sensors comes with 2 half-bridge (350 ohm) weld-on strain sensors with 10 foot cables.

*Custom-ordered leap sensors are available with a direct-to-cellular option where no gateway is needed and the data is sent directly to a cloud server. Contact us for more information.
