Wireless torque sensor adds shunt calibration

TECAT Performance Systems has updated its WISER wireless torque sensor to feature shunt calibration, writes Nick Flaherty.

The new WISER 2030-S will simplify instrumentation verification for users while allowing them to check calibration of the system in the field.

"The 2030-S is the result of listening to and implementing feedback from our customers," said Don Keating, vice president, new business development, at TECAT Performance Systems. "Many have expressed the need for a cost-effective indirect calibration feature to be integrated with our high-speed, high-quality wireless torque sensor.”

The WISER Model 2030-S is comprised of three subsystems. The remote unit consists of the data capture electronics connected to micro-measurement strain gauges, a transceiver, and a long-life battery. The base unit plugs directly into a PC USB port and houses an antenna, transceiver, and up to two analogue outputs. The WISER Data Viewer software is used for system configuration and calibration, live monitoring, and data logging. The WISER 2030-S enables positive and negative shunt calibration with two independent shunt calibration legs using 100 kΩ resistors.

The system is based around the WISER 2000 torque sensor that provides fully processed data on torque, temperature, pressure and vibration directly from the source, while operating in real-world conditions. Output is wirelessly transmitted using a 2.45 GHz radio frequency paired to a base unit.

The remote transceiver has a footprint of just 45mm x 23mm x 6mm and weighs just 8 g, allowing installation directly on the component of interest. This transceiver is also fully balanced with the lithium battery, enabling measurement of shafts rotating at high speeds.

TECAT’s sensor technology is available in two versions: as a Test & Measurement Sensor Application Kit for collecting fully processed performance data, and an OEM version in fully commercialized packaging for automotive, drill rig and motorsports applications.

In addition to measuring torque, the WISER 2030-S has the optional ability to measure 3-axis acceleration, barometric pressure, and ambient temperature, all within a small footprint measuring 36 mm x 23 mm x 4 mm. On-board high-speed data logging with triggering capability allows high-resolution data to be collected on the remote unit without PC or DAQ connectivity, while remote flash enables firmware upgrades without removing the system from the unit under test.
