What is the difference between IP-, TSN- and PRO sensors?
All sensor types are based on the same operation principles and you can use
them all 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. The IP sensor are waterproof.
Do the sensors operate inside a refrigerator or freezer?
Frequently our sensors are being used in temperature controlled boxes, refrige-
rators and freezers, which are located in professional kitchens, laboratories and
pharmacies. Both for hygienic reasons and battery capacity we do not recom-
mend to locate complete sensors inside refrigerators or freezers.
We recommend to use external sensors, which are located inside the low tempe-
rature area and position the electronic circuits and battery outside the low tempe-
rature 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 indi-
cator. In designing the system we identified the great variety of communication
signal levels and did choose for the signal level indicator.
How long will an average battery last?
Good AAA lithium cells will allow the TSN -and PRO sensors to operate circa
one year. The IP sensors with good AA lithium cells can operate about 2 years
or more. In colder areas it is possible that this operation time is considerably
shorter.
What is the difference between BS-500/TL-500, BS-510 and TL-510?
The difference can be found in the internal backup battery for the internal clock.
All other functionality is 100% equal. The battery will operate the internal clock
during a power failure and prevents an (automatic) adjustment to the PC's clock.
Therefore the internal backup battery allows you to continually proceed with the
logging process at power failures. There is also a new BS-750SD receiver al;so
with internal clock battery and an SD card for long time storage.
