Vapour Pressure Analyser RVP-4

The BARTEC BENKE (Germany) Vapour Pressure Analyser RVP-4 is the only available solution on the market for a broad sample spectrum ranging from crude to LPG. The RVP-4 analyser is a result of close communication and listening to customers’ requirements all around the world. The passion for providing the best technical solution to customers and the dedicated service that BARTEC BENKE provides has led to a large installed basis. The latest RVP-4 generation does not require any flame arrestors and is completely certified according to NEC500, NEC505, ATEX and others. This achievement is based on a pneumatically driven piston, which is located inside a large volume-measuring cell. The complete analytical part of the analyser has been laid out to be completely intrinsically safe and can even accommodate for backpressure in a given return line.

Based on the technical highlights, it is possible for viscous sample such as crude to be analysed without the necessity of implementing any additional wash cycles. In fact, the RVP-4 is the only analyser compliant to the ASTM D6377 at measurement temperature of 100°F (37.8°C). It is also possible to measure the vapour pressure at different temperatures e.g. True Vapour Pressure (TVP) for storage tank applications. The robust design of the analyser-measuring cell allows even high volatile and high-pressure samples (e.g. LPG) to be analyzed with an unmatched performance.

The analyser also features all common networking possibilities for customers e.g. Modbus RS485, TCP/IP and others. Another unique feature is the possibility to access and control the analyser via internet connection, which means the BARTEC industrial tablet PC Agile X will be the perfect companion for remote access location requirements. The ex-protected military-spec rugged mobile device withstands shock, vibration and 4-foot drops. It can be operated in a wide temperature range of -20 °C to +50 °C, allowing the tablet to be used in the toughest of industrial environments. With IP65 rating, the device is dust tight, and can withstand water jets against the device enclosure. The huge 10.1” high-resolution display provides perfect viewing for all daylight conditions bringing alive presentations, schematics and applications.  

An upcoming possibility to gain a personal impression of the most sophisticated vapour pressure analyser available on the market today will be at ISA 2015 in Galveston. The BARTEC BENKE team looks forward to present the features of the RVP-4.
