Transmitter module with wireless sensors for MSR385WD Data Loggers

Permanently record temperature, humidity and pressure values using miniature transmitter modules over long periods of time, at operating temperatures from -20 °C to +125 °C, even in inaccessible locations: The MSR385WD wireless data logger, which operates in the 868 MHz ISM band, offers these options.

Due to the high levels of thermal resistance of its transmitter modules (MSR385SM), the new wireless data logger facilitates applications even at high operating temperatures of up to 125 °C. The measured values are transmitted by means of transmitter modules equipped with temperature, humidity and pressure sensors, in the unlicensed frequency band at 868 MHz, across distances of up to 500 m. The optimised power management ensures that – depending on the frequency of measurements and radio transmissions – the power supply to the miniature transmitter modules is warranted for up to five years.

The measured data of the transmitter modules recorded by the data logger can be read out via a USB interface and processed further using the MSR PC software for data analysis purposes. The MSR385WD has a colour OLED display, is capable of storing over one million measured values and can be equipped with up to ten transmitter modules.

Configure your own custom transmitter module for your MSR385WD data logger here!

With a few clicks you are able to select your desired MSR385SM transmitter module. Please note that the transmitter module only works together with an MSR385WD Data Logger. If you don't already own one, please go to the MSR385WD Data Logger product page to order it.

  1. Select the temperature range and the housing of the MSR385SM transmitter module.
  2. Select the sensors for the MSR385SM transmitter module.

1. Select the temperature range and the housing of the MSR385SM transmitter module.

The level of the temperature to which you are going to expose the transmitter module determines the composition of its housing. Therefore, first of all please select the housing for the desired temperature range here.
