Rotronic HL-RC-T Wireless Temperature Measurement Datalogger Technical Information

Radio Frequencies

There are two frequencies available for the transmission of data: 915 MHz with the U.S and 433.92 MHz in Europe and the rest of the world. These are ideal frequencies for optimal transmission of data.

Range

The range of transmission is dependent upon the type of transmission and buildings with ranges of up to 300m available.

Data Logging/Transmission

Up to 30,000 measured values can be stored in the wireless data logger and this data is transmitted and recorded continuously as long as the wireless data logger is located within the vicinity of the receiver.

However, if the distance between the transmitter and receiver is too large or the wireless connection is lost, the data is nevertheless recorded and in this way it is ensured that no data is lost.

Rotronic – Temperature Measurement in the HVAC Industry

Climate control in buildings is generally temperature focused, but increasingly humidity measurement is being considered essential for optimum comfort and energy use in the HVAC industry.

Temperature Measurement Applications

Air conditioning control (BMS) – low cost, low specification products are generally used in this market (+/-5%rh, +/-1°C). Installing Rotronic sensors and dataloggers provides better accuracy and long term stability.

High specification HVAC installations requiring IP65 ingress protection – swimming baths, saunas, clean manufacturing areas.

Air handling system control and to balance air distribution systems by monitoring fresh air intake.
