ETL launches new pressure transfer standard

The ETL Group is introducing a new high-accuracy pressure and barometric standard transfer unit. Designated the model 745, it is designed to give extremely accurate pressure measurements with a resolution of 0.0001 per cent and 0.008 per cent full scale accuracy.

Incorporating the latest state-of-the-art Digiquartz transducers, it is able to cover a maximum of 25 absolute and gauge pressure ranges of up to 40,000psi (276MPa) with exceptional accuracy, reliability and stability. The 745 has a simple easy-to-read front panel and this, in conjunction with the rear panel RS232 computer interface, makes this product suitable for high-performance calibrations.

The innovative 745 gives immediate readings of the pressure values in any of nine different user-selectable engineering units. All pressure readings are temperature compensated and linearised. Other capabilities include tare functions, pressure and temperature units, resolution, sampling time, number of display units, communication settings, baud rate, and sensor address, and a password that can be selected via the front panel menu.

Choices for the second-line display include an analogue pressure bar graph, sensor temperature, rate of pressure change and stored text or external text. Software is included to read and log data via the RS232 port.

The unit weighs only 1.8kg and is in a fully self-contained, CE-marked case, and is powered from its AC adapter or for up to 20 hours by four AA cells.

This versatile product has applications in metrology, aerospace, meteorology, oceanography, energy exploration, reference barometers and laboratory instrumentation.
