TECAT WISER 4000 Wireless Torque Measuring and Monitoring System Serves Automotive Applications
July 12, 2016 by John Day
Automotive applications for TECAT’s WISER 4000 wireless torque measuring and monitoring system include monitoring strain in flex plates; measuring torque in pulleys, pistons, and all manner of shafts; and measuring temperature and vibration to predict failure in U-joints.
The WISER 4000 system is designed to simplify instrumentation verification for users while allowing them to check calibration of the system in the field. The WISER 4000 has been enhanced with two additional programmable analog outputs and higher-speed recording, and it is available with custom-built remote enclosures to protect the system’s remote unit and battery from damage due to debris.
“For autonomous vehicles and smart cars, wireless sensors play a pivotal role in the communication of accurate drivetrain data to the cloud,” said Don Keating, vice president, new business development, at TECAT Performance Systems. “We’re looking forward to meeting with vehicle engineering teams at the Sensors Expo & Conference and demonstrating how our WISER 4000 system delivers a faster, more flexible, and reliable tool to meet this need.”
TECAT’s WISER systems are the smallest, lightest, and most power-efficient solutions available for the measurement of torque, acceleration, pressure, temperature, distance, and magnetization. The WISER 4000 comprises three subsystems. The remote unit consists of the data capture electronics connected to Micro-Measurements strain gages, 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 four analog outputs. The WISER Data Viewer software is used for system configuration and calibration, live monitoring, and data logging. The WISER 4000 enables positive and negative shunt calibration with two independent shunt calibration legs using 100 kΩ resistors.
In addition to measuring torque, the WISER 4000 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 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 removal of the system from the unit under test.
“Besides the applications for which WISER has already been proved, we can foresee additional uses such as gyroscopes, MEMS-type sensor chips, and output drivers and input conditioning for many types of analog sensors,” added Keating. “Our customers already tell us that they can now get data directly off parts in rotating or translating motion where they previously relied on secondary measurements to infer the data.”
