FE01

 


Each FE01 is a complete multi-channel acquisition system specifically designed for accurate measurements of surface temperatures and / or thermal fluxes. The device includes sensors for measurement, signal conditioning circuitry and circuitry to interface the radio modem.

A radio modem of RM01 family can be directly connected to the DB9 connector of FE01 and once connected both devices are powered by the internal battery. Just add a radio modem to a FE01 device and you get a complete measurement node able to communicate with DL01 or DL02 dataloggers.

All the configuration parameters, such as the sampling time Ts, are stored into the internal non-volatile memory. Every Ts seconds, FE01 converts the sensor signals into digital signals and sends them into a data packet to the datalogger.

Thanks to a low-power electronic circuitry, each measurement node is able to operate with very high autonomy; the battery life can vary from one day (Ts = 1 s) up to several months (Ts > 1 min). The battery, internal to the radio modem, is rechargeable and can be fully restored within a couple of hours.

 

Construction details

HFS_2

Each FE01 is capable of handling from 1 to 4 independent measuring channels. There are various models of FE01 with different number and type of the sensors used.

The FE01 devices are pre-calibrated and interchangeable with each other. Since the datalogger is able to automatically detect the number of channels and the related physical quantities, it is not requested by the operator any further configuration.
