The OMEGA RTD-to Wireless Connector/Converter System features stand-alone, compact, battery-powered RTD connectors that transmit their readings back to a host receiver up to 120 m (400') away. Units can be programmed in the field to accept 0.00385 or 0.00392 curve 3-wire, 100 Ω, Pt RTDs, so they can wirelessly transmit the measured temperature, along with the connector ambient temperature, RF signal strength and battery condition to a remote host, such as the UWTC-REC Series. You can program the UWRTD to transmit your data at rates from once every two seconds to every 2 minutes.

The UWRTD is compatible with the UWTC-REC family of wireless receivers, which can accept signals from up to 48 wireless transmitters, and display them on a PC. Receivers are available with optional display and analog output. An analog output can be used to interface with a process controller, PLC or data acquisition device. Each unit includes free software that converts your PC into a monitor, chart recorder or data logger. Readings can be saved and later printed or exported to a spreadsheet file.
