Chatter® is developed for monitoring and measuring of, among other things, level where no permanent power supply is available.
Chatter® contains a built-in multi-channel data logger, a GSM/GPRS modem including a battery which ensures more than 5-year life time on the battery for one call a day.
Chatter® transmits data over the internet to a Microsoft SQL data base by means of the integrated GPRS modem. Furthermore, it sends SMS text with alarm notifications.
Chatter® is housed in an impact-proof aluminium and plastic casing for mounting directly on bore holes and sounding borings where sensor, electronics and antenna are protected from vandalism.
In this configuration log- and call intervals can be preset. Meanwhile the entire system is in hibernation mode, practically without using any electricity. At the chosen log- and transmission time the Chatter awakens, measures and transmits the data. Such a wake up can be as briefly as 10-15 seconds, with means the battery can last more than 5 years. Alternatively, Chatter® is available in an IP 67 / NEMA4 polycarbonate cabinet for wall mounting with a 230/115 V AC or 10-30 VDC supply.
With Chatter®’s analogue, digital and modbus inputs, a connection of new as well as existing measuring units is possible.
To save electricity, Chatter® only supplies the connected transmitters for the time the measuring takes place, typically less than 10 seconds per measurment. By choosing the Modbus connection, measurement signals are transferred to Chatter® with a maximum resolution, since there is no analogue-to-digital signal handling involved in the circuit.
