Specifications

The sensors display different values although they are located next
to each other.
The sensors may all be working with a certain margin. One of the
temperature sensors may deviate 0.5 degree upwards and the other sensor
may deviate 0.5 degree downwards, which would sum up to a difference of
1 degree! Still both sensors may be working within their tolerance levels and
specifications. Other causes for differences may be the local position,
draught and the sunlight respectively shadow position of the sensors.
Are the sensors calibrated and how can we calibrate the system?
We use digital sensors, which are guaranteed to work within their factory
specifications. Some customers (hospitals and pharmacies) order certified
specialists to calibrate their AREXX sensors once a year at their installed
equipment site.
Systematic deviations and tolerances may be compensated by an offset
value in the software.
What is the difference between TSN sensors and PRO sensors?
Both types are based on the same operation principles and you can use both
in one system at the same time. PRO sensors are equipped with a display,
can operate with an external supply from a junction box and are splash proof.
Do the sensors operate inside a refrigerator or freezer?
Frequently our sensors are being used in temperature controlled boxes,
refrigerators and freezers, which are located in professional kitchens,
laboratories and pharmacies. Both for hygienic reasons and battery capacity
we do not recommend to locate complete sensors inside refrigerators or
freezers. We recommend to use external sensors, which are located inside
the low temperature area and position the electronic circuits and battery
outside the low temperature area.
Do the sensors provide us with a battery level indicator?
Unfortunately the sensors do not provide us with a battery level indicator.
There was a choice between a signal level indicator (RSSI) and a battery
level indicator. In designing the system we identified the great variety of
communication signal levels and did choose for the signal level indicator.
