sured solution. The typical output
is 54-60 mV per decade of change
in concentration. The sensor's response
time varies from a few seconds
in concentrated solutions up
to a few minutes in the lower parts
per million (ppm) range. This analyzer
measures CN from 0.2 to 260 ppm.

Limit-value display simplifies
process monitoring
LiquiSonic systems (photo) measure
concentration and density in process
liquids by sonic velocity. In addition
to displaying the numeric concentration,
density and temperature,
the LiquiSonic now also displays the
limit-value ranges, which simplifies the
monitoring of an approximation of critical
values. Users can identify the segment
in the measuring range where
the current value is settled on and get
a quick overview. The LiquiSonic controller
display allows up to three value
ranges at the same time. This applies
for each one of the up to four sensors,
which can be connected to a control
unit. - SensoTech GmbH, Magdeburg-Barleben,

New functionality for this
sensor transmitter
This company has added the nextgeneration
Signet 9950 dual channel
transmitter (Gen 2b) to its flow and
analytical instrumentation product
line. The 9950 Gen2b adds extensive
new functionality to its already proven
capabilities that enable multiple measurement
readings in one transmitter.
This minimizes the number of transmitters
needed, providing cost savings
and greater convenience. The 9950
Gen 2b fully supports the Signet 2751
pH/ORP Smart Sensor Electronics for
pH/ORP measurements. Additionally,
the 9950 Gen 2b automatically
measures pH glass impedance, detects
broken glass and reads stored
data in all Signet DryLoc pH and ORP
electrodes. The 9950 Gen 2b also
supports two new plug-in modules
(photo): the Single Channel Direct
Conductivity Module (3-9950.394-1)
and the Dual 4-20-mA Current Loop
Output Module (3-9950.398-2). -

Moisture analyzer with more
communication capabilities
This company has broadened its
AMEVision communication and display
system capabilities to include
the 3050 Series of moisture analyzers
(photo). Originally designed for
WDG-V analyzers, the AMEVision
system provides realtime moisture
measurements and trend data while
also detailing a variety of maintenance
and troubleshooting information.
Users can now continually monitor
the measurement and diagnostic
information for up to eight 3050 Series
moisture analyzers. AMEVision
enables the convenience of on-site
calibration and communication with
analyzers via Modbus RS485 and
Ethernet LAN. - Ametek Process

An analyzer for residual gases
in vacuum systems
The Leyspec (photo) is designed
for efficient residual-gas analysis
in high and ultra-high vacuum systems.
Due to its compact size and
flexible mountability, the device is
suitable for very different installation
situations and measuring tasks in research
and industry. Equipped with
an integrated display, users can display
the partial pressures of the relevant
gases at any time. If the user is
interested in an additional gas in his
or her process, another channel can
be individually assigned to it. The intelligent
software offers users various
analysis options from which they can
choose. Additional test procedures
and functionalities are pre-installed,
such as the helium leak test or the
setting of warnings and error limits
for certain gases. - Leybold GmbH,

A transmitter for analytical
sensors where space is limited
The Liquiline compact CM82 transmitter
(photo, p. 26) accepts pH,
ORP, pH/ORP, conductivity, oxygen
and chlorine sensor signals from this
company's Memosens sensor platform.
Its housing is only 11 cm long
and 2 cm wide, so even combined
with the sensor, it fits into almost
every assembly, says the company.
Although small, it is a fully developed
