Thermo Fisher Scientific, together with GE Druck, now offers a comprehensive product portfolio of both fixed range and rangeable pressure transmitters, with a wide choice of specifications and price/performance levels.

Specific and economical pressure solutions can be readily provided, using standard ex-stock products or user customised variants, for all areas of industrial use.

From low cost to high accuracy, fixed range or rangeable transmitters can be supplied with fullscale (FS) ranges to 1400 bar gauge or absolute; also compound, vacuum and barometric.

Accuracy extends from the 0.25% FS PTX1400 to the precision 0.05% FS PTX600 series.

The general purpose PTX7500 series offers a wide range of pressure/electrical connections and the RTX1000 a full 10:1 rangeability with LCD display option and integral alarm indication.

All products use the industry standard 4-20mA 2-wire output configuration, powered via a loop supply voltage between 9-30V dc, according to installed loop resistance.

Site adjustable zero and span adjustment is typically by means of integral non-interactive potentiometers and an overpressure of 2 x FS can be applied without change in calibration (containment 4 x FS).

At the heart of every transmitter is an advanced silicon pressure sensing module. Unlike many other manufacturers, GE Druck develops and processes its own silicon technology.

It is highly accurate, reliable, flexible and widely proven in many diverse critical applications, for example aerospace, subsea, motorsport, petrochemical.

The benefits derived from this policy of ongoing improvement and in-house manufacturing have been applied to all products for 30 years.

To complement the silicon technology, a multitude of signal conditioning and packaging techniques have also been developed by the company's multi-disciplined engineering team.

Ranging from the use of ASIC, hybrid and surface mount electronics, to highly compact Hastelloy isolation capsules, these enable the breadth of choice required by today's users to satisfy their varying requirements for electrical and physical interfaces.

ATEX and CENELEC approved versions are available for use in all hazardous areas, supplied with EExia IIC intrinsically safe or EExdIIC flameproof certification.

This enables confident use of the pressure transmitter within potentially flammable or explosive environments.
