Measurement and Testing Testing Vapour Pressure of LPG


Grabner Instruments (Austria), a subsidiary of AMETEK, Inc. has upgraded its top-selling portable vapour pressure tester - the MINIVAP VPXpert. After extensive testing Grabner Instruments has released a new method to test Liquefied Petroleum Gas (LPG) up to 1000 kPa pressure. The MINIVAP VPXpert tests according to ASTM D6897, the Grabner LPG method, which yields results equivalent to the traditional ASTM D1267 bomb method.


The new LPG method is included with all new analysers. Existing users of the MINIVAP VPXpert can also upgrade their analysers for LPG testing free of charge. “In our opinion the MINIVAP VPXpert is the best deal for customers. We are continually improving our analysers by adding new, thoroughly tested methods and features, to give our customers a competitive edge in terms of costs and ease of use,” explains Dr. Oliver Sauer, Director of Marketing & Sales at Grabner Instruments.


Since its market introduction in 2009, the MINIVAP VPXpert has rapidly become the bestselling vapour pressure analyser, taking the lead in innovation from its predecessors, the MINIVAP VPS and VPSH. The MINIVAP VPXpert is a fully configured “all-in” analyser, ready for testing Gasoline (ASTM D6378, D5191), V/L ratio (ASTM D5188), ASTM D6377 (Crude Oil) and ASTM D6897 (LPG up to 1000 kPa). No expensive software or hardware upgrades are required.


The MINIVAP VPXpert was developed by Grabner Instruments, a pioneer and world leader in vapour pressure testing. Grabner Instruments revolutionised vapour pressure testing in 1987 with the launch of the MINIVAP—the world’s first automatic mini-vapour pressure tester that eliminated operator bias and tiresome sample handling that, up to then, had been associated with vapour pressure testing. Over the years, Grabner Instruments has been universally recognised as the worldwide expert in vapour pressure testing, and since 1993, its MINIVAP has served as the U.S. Environmental Protection Agency’s reference instrument for highest precision vapour pressure measurement.

Remote Power When You Need It


Crystal Engineering (USA) is announcing their latest product to complement their line of field calibration equipment. Convenient, portable power is a common challenge encountered during remote calibrations. The new 24VDC Loop Power Supply, model number 24VDCPS, provides a rugged and dependable, easy to use power source with a low noise regulated output, suitable for use with smart transmitters.


Once activated by the On button, power stays on


until disconnected. Users may adjust connections simply by disconnecting and reattaching leads. The Power Hold feature automatically re-activates the circuit when reconnected within 30 seconds.


Bright multi-function icons indicate a powered loop, depleted batteries, and low voltage. Two batteries provide power for up to 14.5 hours. The device works with lithium, alkaline, or NiMH rechargeable AA's, in operating temperatures between -20 to 50°C (-4 to 122°F). The included rubber boot enhances the product’s durability, allowing it to survive drops from 6 feet, and provides a convenient attachment point.


Crystal Engineering designed the 24VDC Loop Power Supply to work well with their nVision Reference Recorder and 30 Series Calibrator. It is available with or without test leads.

Unmanned Helicopters Automate Inspections in the Oil Industry


Netherlands based unmanned helicopter manufacturer, High Eye Unmanned Aviation, introduces a new twist in automating oil industry inspections


An RPAS, or remotely piloted aircraft system, adds unique flexibility to the industry’s non- destructive evaluation (NDE), pipeline right-of-way inspections and other operations and delivers capability that manned helicopters and even fixed-wing unmanned systems cannot offer. Their easy launch and recovery capability, long endurance, low operating costs, as well as the ability to hover for extended periods of time while providing operators with: extensive imaging, data collection in concert with other inspection equipment, recording in HD, IR and other spectrums, make it an ideal platform for a wide range of operations.


High Eye helicopters have been used in 2011 by Shell Oil, Dutch police, French navy, and various Hollywood film and television producers.

VERTILAS GmbH (Germany) announces that their product line of laser diodes for sensing applications has now been extended with a cooled TO-46 package version featuring an integrated TEC and thermistor. This complements the variety of cooled and uncooled packages, available in TO-46 and TO-39 form factors.


Vertilas offers a comprehensive product range of VCSELs from 1.27 µm to over 2.3 µm for NIR gas analysis. All laser products are available in various packaging options, incl. TO-cans and fiber coupled optical sub-assemblies. These package types can be supplied with or without integrated thermo electric cooler (TEC) and thermistor.


Vertilas laser products are based on its unique Buried Tunnel Junction (BTJ) Vertical Cavity Surface Emitting (VCSEL) technology. This technology allows a wider and faster tuning range than other available laser technologies. The circular beam shape of BTJ VCSELs enables an optimised optical system design. Furthermore, Vertilas’ high performance BTJ VCSEL diodes feature very low power dissipation, making them ideal for both high end as well as compact and battery operated sensing equipment.

The heated gas sampling probe JES 301E1SVZ from JCT Analysentechnik (Austria) is designed for continuous use with extractive sampling systems in Zone 1 or 2. It comprises a cut-off valve which allows to shut off the gas flow on the raw-gas side. So this heated gas sample probe can also be installed for over pressure processes or where the sample contains dust and aerosols. JCT´s heated hose series JH can be easily connected to the JES 301E1SVZ by a movable PG42 fastening screw.


The operating temperature of 120°C is regulated by a maintenance free PTC heater. A ceramic filter element with a filter porosity of 2 micron ensures that the gas passes the heated hose free of dust particles. The filter can be replaced easily without any tools while the heated hose stays connected.


The heated gas sampling probe JES 301E1SVZ is extremely robust to provide many years of operation in harsh environment. Typical applications can be found in chemical and petrochemical industry.


A broad range of different materials for In-situ probe tubes and large In-situ-pre filters make the JES 301E1SVZ versatile in application.
