The WISER 2030-S wireless torque sensor from TECAT Performance Systems, is now being protected by a new custom built remote enclosure. Designed to protect the system’s remote unit (electronics) and Li-Poly battery from damage due to debris, the enclosures accommodate a 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 19mm 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.

“Mounting locations for WISER remote units and batteries are often difficult to access once the objects under test are assembled, so not only is there the cost of replacing components damaged by debris, but there is also the subsequent system down-time,” said Don Keating, Vice President, New Business Development, at TECAT Performance Systems. ”To save our customers time and money, our new remote enclosures offer the durability of PA 2200 plastic and the flexibility to accommodate a number of shaft diameters.”

The WISER Model 2030-S is comprised of three subsystems. The remote unit consists of the data capture electronics connected to Micro-Measurements 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 100kΩ 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 36mm x 23mm x 4mm. 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.
