Stable at high temperatures
Plant safety is paramount in the chemical industry. Exact temperature
measurement is thus indispensable, for example, in the boiler sump
or feed.This is to ensure accident-free operation on the one hand but
also to optimize plants and reduce downtime and maintenance.With
the OPTITEMP series, KROHNE offers a wide range of temperature
sensors that cover the needs of the industry and ensure maximum
process reliability.Whether it is an aggressive medium, a high pres-
sure or high flow velocities, as they are common in steam pipes,
OPTITEMP sensors can withstand almost any load.
This is due, among other things, to the special design: We are
using exclusively mineral isolated measuring inserts. They are
characterised by high accuracy, good long term stability and a high
mechanical load capacity. Their ceramic connection block is sealed
in a way that welding connections to the clamps are hermetically
sealed and therefore excellent protected against corrosion. That
helps avoiding failures and reducing costs over the entire life cycle.
Available are standard thermowells following different standards
as well as customised designs, welded multi-part types as well as
bar stock types, with all common process connections. To resist
high chemical loads flange thermowells from stainless steel can be
PTFE coated or protected with aTitanium orTantalummantle. Other
characteristics include explosion protection thanks to intrinsic safety
or an explosion proof design of the thermometer which contributes
to the safety of the plant.

Wireless vibration and temperature sensor for superior machine monitoring
RET Automation Controls is offering a wireless vibration and
temperature sensor. Designed to effectively monitor machines for
increases in vibration and temperature, the sensor measures RMS
velocity inmillimetres per second or inches per second, and tempera-
ture. This enables the sensor to identify machine problems before
they become too severe and cause additional damage or result in
unplanned down time.
The sensor is optimised to work with 1-wire serial radio
devices, such as Banner’s wireless Q45VT Node, the P6
Performance Node and the Multi Hop M-H6 radio. Operators
can easily set vibration thresholds based on the ISO 10816
standard.When a threshold has been exceeded, the wireless
node can provide local indication, send the signal to a central
location, and send the vibration and temperature data to the
gateway for collection and trending.
“Banner’s wireless sensor provides continuous vibration
and temperaturemeasurements to quickly detect anymachine
failure or potential problems,” said Scott Pritchard, director of
wireless global sales, Banner Engineering. “This allows facil-
ity managers to reduce labour costs by eliminating manual
checks and the risk of human error.The wireless vibration and
temperature sensor is ideal for a variety of machine monitor-
ing applications, includingmotors, pumps, blowers andmany
other types of machines throughout a facility.
