The base is the heart of testo Saveris and can save 40,000 readings per
measurement channel independent of the PC. This corresponds to around one
year of memory capacity at a measuring rate of 15 minutes. An emergency
battery ensures that an alarm is transmitted and that no existing data is lost in
the event of a power failure.
The system data and alarms are visible via the display of the Saveris base.
Even without the PC running, the base issues an alarm by means of an LED if
the limit value is exceeded, or optionally via SMS and via a relay output to
which an alarm transmitter can be connected.
In total, a base can incorporate 150 radio and Ethernet probes or 254
measurement channels. The Saveris base is connected to the PC either via
USB or Ethernet cable. The Saveris base thereby offers flexibility with the
highest data security.
The testo Saveris radio probes measure temperature and humidity. In the
measuring cycle, the probes save the recorded measurement data and send it
to the central base at regular intervals. If a limit value is exceeded, a radio link is
established immediately. Through bidirectional transmission, the radio probe
and the base are in mutual contact. This therefore ensures that the
measurement data is only recorded by the base and is not interfered with by
other radio systems.
An alarm sounds in the event that the radio link be interrupted by obstacles.
The memory in the probe ensures that the measurement data is not lost in the
event of an interference in the radio link. An optimized battery design ensures
for long running life of the probe memory.
In free field, the transmission path is approx. 300 m at a frequency of 868 MHz
and approx. 100 m at a frequency of 2.4 GHz. In buildings, the transmission
path is strongly influenced by structural conditions such as walls, refrigerator
doors or metal doors. The radio link can be improved or lengthened with poor
structural conditions by using a router. Because the radio probe and the router
show the quality of their radio link, the probe can personally be positioned
optimally by the user.
Probe versions with internal and external sensors allow the adaptation to every
application. The radio probes are available with or without a display as an
option. Current measurement data, the battery status and the quality of the
radio link are shown on the display.
The two versions of the analog coupler (wireless/Ethernet) allow the inclusion of
further measurement parameters into the testo Saveris monitoring system, by
integrating all transmitters with standardized current/voltage interfaces, e. g. 4
to 20 mA or 0 to 10 V.
