New low cost industrial accelerometers
D
JB Instruments UK Ltd announces the launch of the first few products in its low cost IEPE industrial accelerometer range that will be expanded throughout 2014. The A/140, A/140/S and A/140/C includes a top and side entry 2 pin Mil-C-5015 connector version in addition to an integral stainless steel overbraided cable version. Available immediately these accelerometers have been on sale for some months having successfully been installed at a number of customer sites in Europe. All manufactured from rugged stainless steel welded construction they are well suited to applications such as:
• Wind turbines • Steel mills • Oil pipelines • High speed trains • Machine monitoring • Safety monitoring • Bearing analysis
The A/140 with 2 pin connector weighs just
81grams, has a standard sensitivity of 100mV/g (other sensitivities are available) and is supplied with a ¼-28UNF mounting stud. Cable assemblies manufactured from stainless steel overbraided cable are available to order alongside the accelerometers.

BB has developed a standalone, self-powered temperature transmitter with WirelessHART™, offering a cost effective and maintenance-free alternative to wired or battery-powered devices. Wireless instruments offer the ideal solution wherever it may be costly or impractical to run cabling. Battery-powered WirelessHART technology allows for quick and simple instrument installation to allow operators to monitor new process information to improve plant visibility. However, the battery will eventually need replacing, incurring time and cost. Battery life can be prolonged but only by slowing down the data transfer rate, affecting the instrument’s response time. These challenges are overcome by ABB’s self-powered temperature transmitter. Featuring a built-in thermoelectric generator (TEG), the device uses the Seebeck Effect to harvest electrical energy from thermal energy. The temperature difference between the ambient and the pipe temperature produces a voltage difference, which is then used to power the device.

Norbar warns more care needed in the choice of tools to prevent vibration white finger
ommercial vehicle operators and power tool purchasers are largely unaware of the potential personal injury risks regarding the use of impact guns as a bolting device and this can seriously affect employee health. The issue raised by Norbar Torque Tools, one of the world’s leading manufacturers of torque wrenches, highlights the shortcomings within the commercial vehicle industry in fully protecting staff from Vibration White Finger (VWF) – an affliction more commonly associated with miners. Many workers across the UK are at risk of developing the disease as VWF can afflict anyone using vibrating tools and equipment, even for short periods, so although purchasers of power tools initially look for the less costly option, it does not always ‘pay off’ in the long term. Total compensation paid so far is £1.4 billion and these are the biggest personal injury claims in British legal history and possibly the world.

Tempmaster PRO LABORATORY STANDARD, PRECISION DIGITAL THERMOMETER / LOGGER for Pt100 SENSORS temperature readout is “corrected” accordingly.
The Tempmaster PRO from Labfacility provides very high precision temperature measurement with Pt100 sensors. Data can be displayed
in oC,oF, K or Ω as required. There are two input ports for 3 or 4 wire Pt100 sensors. The measured temperature can be displayed directly from one of the inputs or differentially between the two inputs. Individual calibrated sensors can have up to 10 appropriate calibration values programmed into the Tempmaster PRO.
The instrument then digitally self-calibrates to the associated probe over the range embraced in the calibrated values used; the
A SMART PROBE facility accepts a calibrated Pt100 sensor which carries its own calibration values within the probe.
A flash drive USB port is provided to allow data to be stored and/or exported. Firmware updates are also facilitated via this port.
The PC software which is supplied with the Tempmaster PRO allows remote control, measure and logging. Serial interface with the PC is via a USB connection.

Labfacility offers a range of high quality Pt100 and Pt1000 sensing resistors in wire-wound and thin-film types. New additions to the range include surface mount versions and glass encapsulated types for those applications requiring the highest stability and hermetic sealing.
All Pt100 sensors comply with IEC751 and, depending on construc- tion, are available in Class A, B and 1/3, 1/5 and 1/10 DIN tolerances. Dimensions range from sub-miniature to 50mm length to suit any application and optional extended terminations are available to order.
Labfacility Ltd 38 Bognor Regis: 01243 871280 The new, low-cost surface mount device provides an accurate
and stable alternative to thermistor beads with the advantage of a universal world standard Pt100 interface with a virtually linear
characteristic over a wide range, -50oC to 130oC.
A range of -196oC to 1000oC is spanned by the range of sensing elements depending on the configuration and Ro value (Pt100, Pt200, Pt500 and Pt1000).
