CLEVELAND - OhioPen -- T&D RTR-502B Wireless Temperature Data Logger

CAS DataLoggers supplied a wireless temperature monitoring solution for a company with water storage tanks containing polluted wastewater. The solution needed to maintain a specific temperature range to prevent bacterial growth.

Installation

The company installed 8 T&D RTR-502B Wireless Temperature Data Loggers on their water storage tanks. These data loggers were paired with a T&D RTR-500BW Wireless Base Station connected to their Ethernet LAN to automatically collect data from all loggers.

Usage

Using 900 MHz ISM band wireless communication, the loggers offered a range of up to 150 meters (500 feet) from the base unit. This range could be easily extended using the RTR-500BC base station as a wireless repeater. The loggers' water-resistant cases protected them from accidents, and wall mount brackets simplified installation.

Several base station models exist to collect data from the temperature data loggers, including USB, network, and cellular models. In this case, the customer opted for the RTR-500BW network base station. It connected wirelessly to the 900 MHz radio in the RTR-500B units to automatically download real-time and recorded temperature data and then upload it using a 10/100BaseT Ethernet interface.

The base station could be easily configured using either the T&D 500B utility on a smartphone or the RTR500BW for Windows software on a PC. Data could be uploaded automatically to either a local server running the T&D Data Server software or to T&D's own free WebStorage Service, where it was available to view anywhere via a web browser.

If a measurement exceeded set upper or lower limits, the base station detected the warning and sent an email to up to 4 addresses via the WebStorage Service or Data Server software. A relay contact output on the RTR-500BW also provided a local alarm signal for a light or buzzer to alert anyone nearby.
