Adhesive simply sticks strain gages |
| |
 HBM’s
hot-curing EP150 epoxy resin is supplied ready for use and is applied
directly using a brush integrated in the screw cap. The adhesive can
also be sprayed in mass production applications, for example, in
transducer manufacturing. EP150 is a one-component resin unlike most
other epoxy resins that require additional time to mix different
components before they can be applied. EP150 has very low viscosity and
is very effective. Only a small amount is applied which forms a very
thin, uniform layer of adhesive that properly bonds strain gages. EP150
is used at temperatures ranging from -70°C to +150°C. Two different
packages are available: 2x30ml (1-EP150) and 10x20ml (1-EP150-GP). ... |

CO2 measuring system for monitoring
indoor air quality now with relay outputs |
| |
 The
patented carbon dioxide measuring system from J. Dittrich Elektronic
is now available with two independent relay outputs. As a result, the
MF420-IR-AL measuring system has direct control of automatic window
openers, air conditioning systems and fans. There is no longer any need
for an intermediate device to read and evaluate the 4-20 mA measurement
signals. Controlled interior room ventilation just got even easier. The
MF420-IR-AL measures the indoor carbon dioxide concentration with the
aid of a two-beam infrared photometer, which, thanks to a patented
innovation, is affordable, robust and long-term stable. If the carbon
dioxide concentration exceeds the guide value of 1,500 ppm CO2 specified
for interiors in ventilation standard DIN 1946-2, relay contact A sends
a short pulse, prompting the triggered device to increase the supply of
fresh air (e.g. window opens automatically or fans come on). If the
carbon dioxide concentration falls below a value of 1,400 ppm CO2, relay
contact B sends a short pulse causing the supply of fresh air to be
reduced (window closes automatically, fans go off). ... |

Technology will be held from 6 to 8 May on the fair grounds in Nuernberg.
The conferences and forums complementing this worldwide biggest event is
expected to be attended by 580 exhibitors including the major technology
and market leaders of most product groups. Mechanical Parameters:
Pressure, force, and tension are the major mechanical parameters
generally detected by resistive or piezoresistive sensors. Today,
optical processes – usually based on fibre-optics, which reveal a
change in phase length or light propagation time when elongated due to
strain, for instance – are also available. Among the extraordinary
products at the SENSOR+TEST this year are sensors for monitoring
turbulences in wind channels or for detection of aerodynamic properties
of vehicles and aircraft. At a rate of rise of under 25µs, piezoelectric
transducers attain sensitivities of up to 220V/kPa. Another design, also
with ICP amplifiers, can be used for quick load tests to detect tensile,
compressive, or impact forces, for example, as occur in drop tests or
crash tests. ... |

Radiation Interference Discrimination -
Radiometric measurements and weld inspections |
| |
 BERTHOLD Technologies: Radiometric level gauges have proved
themselves indispensable, especially in the chemical industry, due to
their universal usage and reliability. The measurement is contact-free
and requires no changes to the vessel. They are therefore widely used,
particularly in difficult processes. Problems can occur however, when
weld or material inspections are performed at the plant site. During
these inspections very strong radioactive sources are employed,
sometimes 10,000 times stronger than the source of the measuring system.
This additional radiation field leads to a strong rise in count rate at
the detector and a seemingly dropping fill level. As a result,
considerable problems in the process can occur - in the worst case,
vessel overflow with severe consequences for plant and personnel safety.
Up to now, detectors were often covered with heavy and expensive lead
shieldings. during weld inspections Weld tests were strongly regulated
and the production was often stopped or severly hampered. ... |

Suppression of interference radiation in
radiometric level measurement |
| |
 BERTHOLD Technologies: Radiometric level measurements are
particularly reliable and have a characteristically high availability.
The technique permits non-contact level measurement and is therefore
used especially for difficult measuring tasks. Hitherto, however, the
applicability of radiometric measurements was always compromised
whenever testing of materials or welds was being performed on site. A
newly developed technology now permits the influence of interference
radiation on measurement to be drastically reduced. The very high
activity of the radiation sources used for weld testing gene rate such
strong radiation fields that even radiometric measurements perform ed at
distances of up to 1000 m can go haywire. A new technology has been
developed to prevent this from happening. An LB440-RID radiometric level
measurement system incorporating this new technology was subjected to
extensive field testing by BASF radiometry specialists at Ludwigshafen
in collaboration with Berthold Technologies in order to establish its
applicability in practice. ... |

Mini-Mixer will be the torque of many
industries |
| |
 Sensor
Technology Ltd: A torque sensor is helping analyse recipes’ mixing
properties in a project that could slash development costs in the food
and plastics industry and help nanotechnology advances in the
pharmaceuticals world. The research and development is being carried out
at the University of Bradford by Professor Hadj Benkreira and Dr Raj
Patel in collaboration with Dr Martin Gale, formerly of RAPRA Technology
(Shawbury) now Visiting Professor. They have been developing a miniature
mixer (5-25 grams batch) that incorporates a set of integral instruments
to monitor the properties of materials as they are being mixed. The
instruments work in real time during the mixing process and their output
is captured to a PC for subsequent analysis. Software is being written
so that the analysis can be performed simultaneously with the mixing and
perhaps even used to interactively control the mixer itself. One of the
key parameters to be measured is the torque of the mixing element, as
this will become constant once mixing is complete. This is measured by a
TorqSense non-contact sensor ... |

JUMO ecoLine and tecLine - pH and ORP
combination electrodes for swimming pools |
| |
 JUMO:
The condition of swimming and bathing pool water must by law be such
that it does not constitute a risk to human health. Numerous
measurements are needed for checking the quality of the pool water. The
most important parameters for the pool water quality are the pH value
and ORP. DIN 19643 stipulates which values these two parameters must
have. Depending on the type of bathing water (fresh water or sea water),
the measurements are not allowed to go above or below the range 6.5 to
7.8 pH and 700 to 770 mV. The pH value can affect the disinfection,
flocculation and filtration of the water. An excessive pH will, for
instance, reduce the disinfectant effect of the hypochlorite. The ORP
can be used to evaluate the bactericidal effect of the water in the
pool. This then enables more efficient application of the disinfectant
agents. . ... |
