Datapaq® Introduces the New TM21 Radio Telemetry System for Temperature Profiling

Now designed to support multiple loggers for data transmission in real time
August 01, 2010

Cambridge, UK - Datapaq, the world's leading supplier of temperature profiling systems, introduced the revolutionary new RF Radio Telemetry system TM21 to complement the TPAQ21 and MultiPaq21 datalogger products. The TM21 system utilizes the latest radio frequency technology to allow temperature data transmission from the datalogger in real time. As the Datapaq system travels through the process (oven, furnace or kiln), temperature data can be viewed, analyzed and reported instantaneously. Such a system revolutionizes the way in which many processes can be monitored in a far more efficient and productive fashion. The technology can be applied in numerous applications and industries, including batch oven cooking in the food processing industry, vacuum furnace surveying in the aerospace industry and 3 day kiln firing processes in the ceramic industry.

New features of the TM21 system include:

Multiple Logger Operation – Operates with multiple loggers running at the same frequency and collects data with one installation of the Datapaq InsightTM software

Auto Frequency Set-up – Automatic transmission frequency optimization and selection from software, eliminating interference problems and guaranteeing signal quality.

Intelligent SW Diagnostics – Comprehensive on-screen real time diagnostics reporting signal status for each transmitting logger and receiver

Transmitting Power – Transmission performance optimized for high temperature operation with internal self calibration routines and listen before transmit features

Improved Logger Performance – Reduced power consumption, extending battery life and operating life

Modular Configuratione – The primary receiver can be complemented by a series of secondary receivers positioned at regular intervals along a process to guarantee data quality.

The benefits of combining RF telemetry and temperature profiling speak for themselves. Before the Datapaq datalogger has even left the furnace, oven or kiln, you will have the information necessary in real time to make any adjustments needed in your process to insure product quality and reduce scrap. For many batch processes, such information may permit significant reduction in cycle times, thereby increasing productivity and reducing energy costs. In optimization or validation studies, the ability to see the effect of process parameters on the temperature profile can significantly help reduce process set-up times and allow quicker production start up.
