PRODUCTS EDITOR'S CHOICE ENABLING PRECISE BURNER CONTROL
With the use of burners requiring careful gas control, Bürkert has introduced the MultiMFC Gas Box, which features the latest in precision mass-flow control technology. The new modular package
incorporates precision gas metering, flexible configuration, the latest network communication technology and a simple user interface. It comprises an intuitive touchscreen display that features a prominent system status LED which indicates the operational condition of the controller according to NAMUR standard NE107. In addition, the sensor housing module can be equipped with a variety of mass flow controllers (MFCs) and includes
A NEW DEW POINT TRANSMITTER
Designed to continuously measure the moisture content in gases, Omega’s RHCM-40 Series dew point transmitter is an
optical chilled mirror
high performance hygrometer. Repeatable and reliable,
this uses the chilled mirror dew point temperature condensation principle to determine the water
vapour concentration in gas mixtures and a platinum resistance RTD to accurately measure that temperature. Options include air temperature and humidity measurement.

gas port connections and a polycarbonate window to enable sight of the LED status lights on the MFCs. Due to the range of
measurement sensors and control valves that can be incorporated into the sensor module, this offers flexibility in terms of the variety of gases that can be controlled. Combined with precision and reliability, the gas blending controller has all of the essential qualities required to form the heart of a burner control system, the company states. The self-contained gas
control modules can be used as a mixer or as a distributor that can be easily programmed to control up to 16 MFCs through the touch-screen display; and the unit includes full data logging capability.

MEMS ACCELEROMETER RANGE FOR HIGH TEMPERATURE USE
The Colibrys TS1000T series of high temperature MEMS accelerometers is now available from Acal BFi. Offering stability, shock resistance,
and low non-linearity and noise, these operate at a temperature range from -40˚C to 150˚C for more than 1000 hours, and can withstand intermittent temperature exposure of up to 175˚C. In addition, an embedded temperature sensor compensates for thermal errors to achieve accurate, reliable readings. The series is available in three ranges,
±2g, ±5g and ±10g. It is based on Colibrys’ proven MEMS technology, which is said to push the boundaries
PORTABLE VIBRATION CALIBRATION
Now available from Svantek is the robust SV110, a portable vibration calibrator designed for verification of machine sensors as well as on-site checks of human vibration accelerometers, in accordance to ISO 8041. This has been developed for in-situ calibration checks of hand-arm vibration meters mounted on the hand or tool, and is said to be ideal for use with Svantek’s SV103 and SV106 instruments. Depending on the selected frequency (79.58 Hz and 159.2 Hz), the user can select the level of calibration from 1m/s² to 10m/s². Accelerometers are attached using mounting stud or disc, or via a dedicated adapter. The calibrator menu provides selection between both metric systems ‘g’ and ‘m/s²’. The menu is simply operated by three push buttons and a small OLED display. This also features a built-in reference accelerometer that measures the cross- axis (transverse) vibrations to detect any disturbance to the calibration signal.

of vibration and shock endurance for heavy duty and harsh environment applications such as down-hole measurement while drilling, directional drilling, borehole surveys, geological exploration and logging while drilling. Martin Kemp, European business
development director for Sensors at Acal BFi said: “The addition of Colibrys’ TS1000T range to our existing harsh environment sensor portfolio enables us to offer our customers the most innovative and high quality sensors available on the market.”
