1. Introduction
The
AQUATRACE IV
devices
are a further development of our proven series of moisture trace
measuring instruments, which work on the basis of P
2
O
5
sensors and can be used
to determine
the humidity in all gases (except NH
3
) in the coarse and fine ppm
V
range. The measuring
system consists of an electronic measuring instrument and a separately installed measuring
cell that can be integrated into a gas handling system. The measuring instruments are available
as:
1.
Laboratory device (portable version) - Model T
2.
Laboratory device with battery (portable version) - Model A
3.
Industrial device in 19" rack ( 3 U ) or - Model R
4.
Wall Unit (IP65) - Model W
2. The basic instrument structure of the AQUATRACE® Analyzer
2.
Depending on the version, the devices can process up to a maximum of 4 independent
channels (humidity sensors)
3.
The display is designed as a touch screen and thus dispenses with susceptible controls
4.
The 7" graphic display with a resolution of 800 x480 pixels shows the time-dependent
course of the measured values for one or all integrated channels.
5.
The run-in process after recoating is represented with logarithmic scaling. After falling
below the upper measured value scaled for the channel, the display automatically
switches to linear scaling.
6.
The re-coating of the sensor is menu-guided.
7.
The menu navigation is largely self-explanatory
8.
Optionally, the display can be set in ppm
V
or Dp in°C. The conversion is done
automatically using the Magnus formula
9.
The user language is adjustable. It can be selected from 9 languages
10.
Production according to ISO 9001
11.
The device design follows the current NAMUR recommendations, according to which
status signals for failure, limit exceedance, maintenance requirements, device in
maintenance
should be provided as potential-free relays.
12.
An automatable sensor test enables the self-monitoring of the
Device
13.
All changes and settings are secured by password protection on several levels
(operator, engineer, administrator)
14.
Calibration and adjustment with separately available dongle necessary
15.
The analog output (4....20 mA) is freely scalable
16.
The device records all measured values and changes to the device per channel in the
background and has a USB interface via which all data can be read out as a logbook in
CSV format.
