Wire-free monitoring
September 1st 2008 Hanwell Instruments' new rl4106
temperature and humidity
transmitter is the latest addition to
its 4000 series of radio
radiologgers. The 4000 series
enables wire-free monitoring of a
site, with real-time alarm
notification, and allows historical
analysis of the data.
Each unit reads its on-board
sensors to provide accurate
information about environmental
conditions. Data is transmitted, at
user-defined intervals, to the base
station that logs and stores the
data pending transfer to a PC for
analysis and archival storage.
The rl4106 has two sensors as
standard: a precision temperature
probe and a high quality humidity
probe. These can be mounted
internally to the transmitter body,
externally on the case or remotely
on a probe. An additional surface
temperature probe can be added
to check dewpoint margins.
Sensors can be calibrated by the
user or at Hanwell's in-house lab.
ID number and transmission rate
are set in the rl4106 using a simple
software program (free to
download) and a USB cable.
Each unit has an LCD screen
displaying the most recent
readings taken and predicted
battery life. More articles from Hanwell Instruments - Lamerholm: |
