Protection for sensor's remote unit and battery

Jon Lawson

TECAT Performance Systems introduces new custom-built remote enclosures for its WISER 2030-S wireless torque sensor. Designed to protect the system's remote unit (electronics) and Li-Poly battery from damage due to debris, the enclosures accommodate a wide range of shaft diameters and can be attached with one- or two-hose clamps.

Available as optional accessories, the WISER 2030-S remote enclosures are made of a rugged plastic material designed for high impact strength. The enclosures consist of a black base and a red cover for the remote unit and white cover for the Li-Poly battery. The base is available in three sizes with heights of 15mm, 16.5mm, and 18.5mm for shaft diameters from 19 mm to > 60.3mm. The enclosures feature an operating temperature range of -40 °C to +80 °C, and allow for maximum RPMs to 15,000 when secured to the shaft under test with a two-hose clamp.

TECAT's WISER systems are the smallest, lightest, and most power-efficient solutions available for the measurement of torque, acceleration, pressure, and temperature. The WISER Model 2030-S is comprised of 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 two analog 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.

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.
