ETL Group - New High Accuracy Multi-Range Pressure Standard

ETL Group : 28 June, 2007  (Company News)
A new innovative multi - range pressure standard for a wide variety of high accuracy pressure measurements for calibration, testing and transfer standard applications is now available from the ETL group. Designated the 785 it incorporates one or two Digiquartz absolute or gauge pressure transducers, which are used exclusively as reference standards.
Multi - ranging allows each Digiquartz transducer to replace three separate transducers. The two transducer model has six ranges, with push button selection between measurement modes, local configuration and customer set ups.

The easy to read display shows functions such as rate of change, pressure, maximum/ minimum pressure, average pressure deviations, and operator triggered instantaneously readings.

There is a choice of 25 different transducers with up to 75 active multi ranges available. The range cover vacuum to 40,000 psi (275 Mpa), have a resolution to 1 ppm (user - settable) and are fully compensated fom -20 to +100 degrees C.

Communications to a host computer is via RS-232 or IEEE-488. All transducers are protected by a self defense system to prevent over pressure damage as high as 1,500 psi, and may be dynamically compensated for atmospheric pressure changes during measurements.

This compact easily transportable unit can be used both on and off site and has applications in the Metrology, Aerospace, Hydrology, Meteorology, Oceanography, Nuclear, Laboratory and Manufacturing Industries.
