The device accepts up to 4 analog inputs from resistive temperature sensors, which are also provided as part of the solution. These include pipe clips for a variety of pipe diameters, which are simple to install, with sensor cables of varying lengths (0.5m – 3m).
The device uses the SIGFOX network to transmit temperature profile information to the devicepoint™ platform – this means that there is no requirement to integrate or interfere with any of the onsite/local IT or networking systems – the solution does not require any local networking support (e.g. Wifi). The device monitors all 4 temperature inputs once every 5 seconds, analyzing and reporting key information (hourly temperature summary, daily summary, key temperature change profile events, and status information) in near real-time.
The device is battery powered, and can be configured remotely to alter its power mode and other operating parameters. In its ‘long life’ mode, the device will continue to operate for up to 8 years.
The device is IP55 rated so can be used in damp/moist environments.
Please note: this is not a datalogger – it does not store any temperature data locally. The device analyses temperature data locally and transmits information to the Devicepoint platform using the SIGFOX network. Temperature profile information and events can be customized to meet customer requirements.
