Fast delivery for standard or bespoke strain gauges
Choice of
enclosures for new Rate Totalisers
ew pulse input Rate Totalisers include the features and functions most frequently requested by users of previous BEKA totalisers, including smaller enclosures for applications where panel space is limited, rugged 316 stainless steel models for marine and severe environments and even larger displays in the 144 x 72mm models. All have IP66 front of panel protection and include a lineariser, with an optional display backlight, isolated synchronous pulse output, isolated 4/20mA output and dual alarms.

Intrinsically safe models have ATEX, IECEx, US and Canadian certification allowing worldwide installation in gas and dust hazardous areas. For applications in Zone 2 or 22, Ex nA and Ex tc approval permits installation without the need for Zener barriers or galvanic isolators which significantly reduces installation cost. Although well documented and easy to configure
on-site, these Rate Totalisers can be supplied configured with scale card marking to customers requirements for no additional charge.

n addition to the sales and support of ZEMIC’s wide range of standard and special-purpose strain gauges, Variohm EuroSensor supplies user-customised designs from its distribution partner with industry leading lead times. Standard delivery across ZEMIC’s eleven ranges is approximately 18 working days with specials only adding between 5 and 10 working days – most of the gauges are directly equivalent and interchangeable with other leading brands and in general have better specifications. Eleven range options and thousands of permutations are available with Constantin, Karma and special purpose grid foils in a variety of patterns and gauge lengths, along with several types of backing material, temperature and/or elastic modulus/creep compensation options, and termination tab variants. Fast availability for customised strain gauge designs will appeal to OEMs who require evaluation samples and those wishing to develop applications where strain gauge performance needs to be optimised. Variohm can specify custom modified designs to exactly suit industrial and research applications
ranging from electronic weighing to machinery load cells and from precision transducers to stress analysis. Dedicated sales engineering support is available for clamping techniques, concrete and irregular materials installation, high elongation, surface preparation, terminations and more. A new Strain Gauge Selector is available for customers to submit custom strain gauge requirements to Variohm. Variohm EuroSensor is a manufacturer, distributor and supply chain partner providing complete sales and application support across a comprehensive range of position, force,

New nanosponge Surface Enhanced Raman Spectroscopy substrates
O
cean Optics has introduced a new substrate for Raman spectroscopy applications. The new RAM-SERS-SP Surface Enhanced Raman Spectroscopy substrates use a proprietary gold- silver nanosponge alloy to produce highly sensitive,
trace-level
Raman spectroscopy measurements. The applications for SERS range from detection of explosives and narcotics, to food safety, anti-counterfeit tagging and biological research. SERS substrates amplify very weak Raman signals by many orders of magnitude. Fast, repeatable measurements of SERS-active
analytes are possible even to parts-per-trillion levels. Silver-only SERS substrates work best with 532 nm Raman excitation, and gold substrates are better suited to 785 nm Raman systems. By combining the silver and gold on one substrate, the new SERS nanosponge substrates perform well with either wavelength

New IP67 high temperature
he compact monitor delivers fast, accurate, in-line transmittance
readings in industrial process and drinking water settings, where UV disinfection is used. Patented automatic wiping and calibration mechanisms significantly reduce maintenance burden and extend service life. UV Transmittance measurement with the UVT-LED-PW ensures proper UV dosing and efficient operation of UV disinfection systems. Simple to operate, with a clear backlit LED display, the UVT-LED-PW is mounted directly in a pressurized pipe or sampling line, taking automatic measurements every 60 seconds. The sensor directly outputs a 4-20mA signal for UV system control or data logging. Patented cleaning and calibration features ensure UVT-LED-PW measurements are accurate and reliable. The integrated Teflon wiper delivers a swift cleaning cycle before each reading is taken, to prevent fouling and build-up in water and wastewater applications. The sensor automatically calibrates to a quartz reference standard built into the wiper mechanism

ansford Sensors, the leading UK manufacturer of high performance industrial accelerometers, has launched two new cable and connector sets for use with its existing range of vibration sensors. The new HS-AC334 and HS-AC335 cable assemblies have been developed for use in applications where IP67 sealing is required, or where vibration sensors have to be used in extreme operating temperatures. The new cable assemblies are rated for use between -80 and +200 degrees Celsius and are manufactured from FEB (Fluorinated ethylene propylene). This is flexible, robust and provides excellent dielectric strength, making it ideal for a wide range of industrial and process duties. The HS-AC334 and 335 can be supplied with
accelerometer cables H
straight or right-angle two-pin MS connectors, or with three-pin connectors for use with dual output sensors, and are available in a variety of standard or custom built lengths.
