ROUND UP
New relative humidity probe that hands control to the user
Michell Instruments, represented in South
Africa by Instrotech – a Comtest Group
company – has introduced the new Hy-
groSmart HS3 advanced interchangeable
relative humidity and temperature probe.
It is 100% configurable, giving users maxi-
mumflexibility. It also allows for alterations
to RH measurements, to keep step with
changes or developments in the process.
Users can set the zero/span range, out-
put signals and choose from five output
parameters (including dew point). All
these changes and settings are made on
a PC via the application software.The unit
can also be ordered directly from Michell
with the probes fully configured to unique,
individual specifications.
The new probe ensures zero process
downtime by keeping maintenance to a
minimum with an interchangeable sensor.
When recalibration is due, the old Hy-
groSmart HS3 sensor is simply exchanged
for a new, freshly calibrated one. This
simple procedure allows for the probe
to remain installed, and takes only a few
seconds to carry out. Using the replace-
able sensor ensures that the HygroSmart
HS3 probe has a low life-time cost, when
compared to fully disposable probes. Alter-
natively, minor calibration adjustments can
be easily made on any installed HS3 probe,
with a 5-point digital trim adjustment via
the application software to ensure maxi-
mum accuracy without needing to replace
the sensor.

Entry level vibration monitoring system
By monitoring vibration, the condition of
rotating machinery can be effectively deter-
mined. A vibration monitoring system can
give early warning of impending failures
and therefore prevent failure, reduce forced
outage, maximise utilisation of assets, in-
crease the lifetime of the machine, and at
the same time, reduce maintenance cost.
Engineers at R&C Instrumentation decid-
ed to put together an entry level vibration
monitoring system for applications where
it is not cost effective to install expensive
vibration and condition monitoring hard-
ware and software.
The system consists of a loop powered
vibration transmitter connected to a pro-
cess indicator. The process indicator has
programmable alarm relay outputs with a
separate 4-20milliamp re-transmission out-
put.The indicator also doubles as a 24 Vdc
power supply for the vibration transmitter.
The vibration transmitter is fastened to the
equipment to be monitored by means of an
8 mm mounting stud. Simply drill and tap
an 8 mm hole and screw the transmitter
into it. The system is supplied complete
with Process Indicator, vibration transmitter
and 2-pin MIL connector.

Improved speed, precision in analysis of light elements
SPECTRO Analytical Instruments has upgraded the SPECTRO xSORT handheld X-ray fluo-
rescence (XRF) spectrometer – delivering improved speed and precision in the analysis
of light elements.The design, performance, and simple operation of the SPECTRO xSORT
handheld spectrometer make it ideal for performing Positive Material Identification (PMI) for
infrastructure integrity testing at refineries, power plants, and petrochemical complexes ‒ as
well as scrap metal analysis and sorting in the recycling industry.
The SPECTRO xSORTAlloy model delivers grade identification in seconds.The even more
powerful SPECTRO xSORT AlloyPlus analyses most alloys in two seconds, and identifies
alloys based on light elements such as aluminum, magnesium, silicon, phosphorus, and
sulfur in seven seconds. Advantages include: Ease of Use:With SPECTRO xSORT, operators
don’t have to switch methods between samples, or bother with helium flushes or vacuum
systems. Its compact, one-piece 1,64 kg (3,62 lb) design is optimized for easy use in the
field, even in tight or less accessible spots. Built-In Protection and Calibration: A shutter
that automatically closes the measurement window between analyses ‒ to protect internal
components ‒ also functions as the sample material for unique, automatic iCAL standardisa-
tion. All calibrations loaded into SPECTRO xSORT are always ready for use.

New diaphragm
pressure gauge for
hygienic processes
From hygienic case design to small
process connections, WIKA has tailored
its new PG43SA-S diaphragm pressure
gauge to the requirements of sanitary
applications. With this, there is now
a mechanical measuring instrument
available for safe pressure monitoring
in hygienic applications. Its measur-
ing principle, with a flush welded dia-
phragm, enables mechanical pressure
transmission, whereby the risk of prod-
uct contamination through a transmis-
sion fluid is eliminated. As a result of its
high overpressure safety, the instrument
can also withstand critical process con-
ditions.The operational flexibility of the
PG43SA-S is supported through a large
selection of small process connections -
for example, to DIN 32676 (clamp) or to
DIN 11864.Tested in accordance with 3-A
Sanitary Standards, the pressure gauge
with hygienic case is CIP, SIP and wash-
down capable. It can thus be cleaned
reliably and time-efficiently. An easily
accessible zero adjustment on the top
of the case enables calibration if needed.
