Thermal imaging cameras
help spot problem areas
Heat Spy thermal imaging cameras
(photo) are available in two
series with 16 different configurations
to suit a variety of applications.
The z30 Seriew " Detector "
is designed for on-the-spot maintenance
inspections and repair. The z50
Series " Inspector " includes additional
features for documenting and preparing
reports with ease, including thermal
and digital images. The base z30
Detector model features 11 languages,
four color palettes, °C, °F or K measurement
scales, hot-cold seeking and
two fixed-spot measurements, as well
as freeze-frame for viewing the current
image. Units can be upgraded in
the field to expand the functionality
as needed, for instance to extend the
temperature range or to include wideangle
and telescopic lenses. - Wahl

Service installs thermowells per
new ASME standard
This company's thermowell calculation
service is now based on the new standard
created by the American Society of
Mechanical Engineers (ASME) that establishes
the practical design considerations
for thermowell installations and
helps improve overall reliability of temperature
measurement (photo). ASME
updated its standard on thermowells
from the previous standard, created in
1974, to create the ASME PTC 19.3TW
- 2010. Using this new standard, this
vendor's specially trained team provides
recommendations on thermowell
design and installation best practices.
Calculations that follow the ASME
PTC 19.3TW - 2010, provide the most
up-to-date, accurate and complete thermowell
recommendations. By using
outdated standards to calculate thermowell
size, there is an increased risk
of failures due to increasing line sizes

Wireless multi-input temperature
transmitter accepts eight inputs
The YTMX580 (photo) is a new wireless
multi-input temperature transmitter
built on the ISA100.11a industrialautomation
wireless-communication
standard. The YTMX580 is battery
powered and features eight analog
input channels, each configurable for
thermocouple, RTD, DCV and 4-20mA
measurement. The YTMX580 is
a cost-effective way to measure multiple
temperature points in distant
plant locations where there is no signal
cabling or power available for traditional
wired instrumentation. With
eight input channels, the YTMX580
increases operating efficiency and
reduces installation time and maintenance
costs by combining multiple
inputs into a single transmitter. -

Log temperatures without the
need for wires
The RTR-505Pt wireless temperature
logger (photo) features a large LCD
display, holds 16,000 readings and is
IP64 water resistant. The possible temperature
range of the RTR-500Pt can
be from -199 to 650°C depending on
the sensor selected. The unit is comCHEMICAL
