The WISER TC2-K is comprised of three subsystems: a remote unit, base unit, and software interface. The remote unit consists of the data capture electronics connected to two K-type thermocouples, a transceiver, and a long-life battery. A custom-designed mounting plate allows for installation in any specific wheel hub or application.

The base unit, which houses an antenna and receiver, plugs directly into a PC USB port for use with the software interface, or into a power supply and data acquisition system via its four analog outputs. The WISER Data Viewer software is used for system configuration and calibration, live monitoring, and data logging.

TECAT's WISER systems are the smallest, lightest, and most power-efficient solutions available. The WISER TC2-K's remote unit measures only 89 mm by 42 mm and weighs 350 g. Low power consumption enables long battery life for uninterrupted testing, while a noninvasive design allows the unit to be removed without altering the unit under test.

For extreme wheel hub environments, the system provides accuracy of ± 1 °C over an operating temperature range of - 40 °C to + 1000 °C.
