The
newly developed pressure transmitter MIDAS S05 from JUMO offers a
high quality at a low price. This was reached through a consequently
cost-oriented design, the use of modern production technologies and a
maximum of automation. The completely welded measurement system made of
stainless steel is suitable for almost all media and the use under the
rawest conditions. It offers optimum safety in view of a leakage of the
process agent. The used silicon sensor itself can endure extreme burdens
in the lowest measurement range of 250 mbar and can perform millions of
pressure cycles. Especially this durability while under extreme pressure
is important for applications in the area of pump control, since here
often pressure peaks and cavitation must be considered. There are many
areas of application in cooling and air conditioning facilities, in
compressors, in mechanical engineering, in the field of commercial
vehicles and in industrial pneumatics. For the connection to the process
there are a number of thread forms and sizes. ...
With
the digital temperature switches of the ETTN-YTTN range, Baumer’s
product segment Process Instrumentation offers robust measuring
instruments for temperature control for industrial process management.
The devices are made completely of stainless steel and are particularly
suitable for the use in severe industrial environments. A special design
with a clamp-on sensor enables easy mounting at a pipe with two standard
clips. It can measure the temperature of a process without direct
contact to the medium. Based on microprocessor technology, the
temperature switches can be programmed completely on site by using code
protected keys. They have two threshold outputs, PNP transistors or
galvanic isolation. The output signal can be analogue (4 to 20 mA) or
digital (RS485 Modbus). The devices can measure a scale from -200 up to
+400°C with an accuracy of ± 0.5°C. Errors due to thermal resistance of
the pipe or thermowell can be corrected by manually entering the process
fluid temperature into the ETTN. ...
The
IMI Sensors division of PCB Piezotronics (PCB®) has released the
industry exclusive Model 699A02, a portable, lightweight, battery
powered industrial handheld shaker, designed to conveniently verify
accelerometer and vibration system performance, as well as confirm the
operation of interconnecting cables, switching devices and monitoring
systems. The unit operates at 159.2 Hz and delivers a controlled, 1 g
RMS or 1 g peak acceleration to test accelerometers and vibration
sensors weighing up to 250 grams. Model 699A02 is ideal for field
troubleshooting predictive maintenance and condition based monitoring
systems, and can be used to verify sensor calibration and performance
right at the machine, including permanently mounted accelerometers. ...
J.
Dittrich Elektronic GmbH & Co. KG: If pupils are conspicuously tired
during lessons, lack concentration or fidget around, it is due to stuffy
classroom air caused by poor ventilation or the lack of it. This has now
been confirmed by a study carried out at Bremen University under the
leadership of Dr. Gerhart Tiesler. The scientists measured the carbon
dioxide concentration during lessons in three different schools. Without
separate ventilation, the CO2 concentration in the classroom had a
detrimental effect on the pupils' work after just 20 minutes. As the CO2
content in the indoor air increased, the pupils became increasingly
inattentive and tired. CO2 values above the DIN 1946 guide value of
1,500 ppm resulted in slower processing of visual and audio stimuli. By
contrast, the pupils responded to additional airing with increased
attentiveness, lowered physical stress, reduced noise level and a more
intensive teacher-pupil dialogue. ...
Leuze:
Safety officers must know about changes in the world of standards. This
is why the Safexpert Version 5.5 now includes a NormManager (standards
manager), which immediately presents changes in the Official EU Journal
(with regard, for example, to EN ISO 13849-1). Gone are the days when
users regularly received CD ROMs with updates and had to do laborious
research work. As soon as Safexpert starts, the user is asked if
NormManager should be activated to access the Internet and request
updates from the NormManager Live Server. After the prompt the user
immediately sees the topics where changes have been made. Further
information can be retrieved directly and in detail. This applies to
document status, CE symbols, international compliance, and both
predecessor and successor documents. ...
