PTX 600 Series

Druck Precision Pressure Transmitters

Features

• Ranges 1.5 (100 mbar) through 10,000 psi (700 bar)

• High overload and burst pressures

• Gauge and absolute

• Instrinsically safe

GE’s well proven silicon technology has been developed to provide a miniature micro-machined diaphragm which is electrostatically bonded to a glass substrate and stitch bonded within a glass to metal seal assembly to provide exceptional thermal and stress isolation.

• ±0.08% full scale (FS) best straight line (BSL) accuracy

• ±0.1% FS stability

• Thermal performance 1%, -4°F to 176°F (-20°C to 80°C)

For critical applications in industrial and research environments, the PTX 600 Series of two wire, 4 to 20 mA output pressure transmitters oers high levels of stability, versatility and measurement accuracy from a robust device.

The glass to metal seal is completed with an electron beam welded Hastelloy C276 isolation diaphragm and 316 stainless steel pressure port. The reduced internal volume of this assembly and advanced design features of the sensor signicantly improves the stability and thermal performance of the transmitter.

The two-wire electronics incorporate power supply regulation and amplier stages with independent zero and span controls, reverse polarity and over voltage protection with an RFI bulkhead providing feedthrough lters within the body tube assembly.

The PTX 600 Series provides the user with a high accuracy, high stability pressure transmitters, based upon well proven techniques with the benet of the latest sensor and electronics technology within a rugged, compact design able to withstand the severity of industrial sites and still provide the performance of a precision instrument.

A high level of protection against electrical interference has been combined with surface mount components and total potting of the electronics to ensure integrity under high levels of shock and vibration, with environmental ratings dependant upon the electrical connection selected.

The PTX 600 Series features high accuracy, 0.08% FS Best Straight Line for the combined eects of non-linearity, hysteresis and repeatability, and to fully represent operating conditions, the thermal eects are expressed as a maximum change in output from the calibration at room temperature.

Every sensor is fully calibrated and compensated for thermal eects, and then stocked as a “core” (PTX 600 Series) with the test results in standard pressure ranges.

Prior to dispatch the core is adjusted to the customer specied ranges and pressure units (if required) and completed with the appropriate electrical connection format.

PTX 600 Series Specications

Pressure Measurements

Operating Pressure Range

Any pressure unit and (zero Based) span available between:

• 1.5 psi (100 mbar) and 900 psi (60 bar) gauge

• 900 psi (60 bar) and 10,000 psi (700 bar) sealed gauge

• 3.6 psi (250 mbar) and 10,000 psi (700 bar) absolute

Standard Ranges

• Any pressure range and engineering units available, e.g. inH2Og, mH2o, mmHg, etc.

• Compound, oset and reversed outputs are available e.g. -15 to 15 psig (-1 to 1 bar), 15 to 45 psig (1 to 3 bar), 45 to 0 psig (3 to 0 bar), for further information please refer to manufacturer.

Overpressure

The rates pressure can be exceeded by the following multiples without degrading performances:

• 4X for ranges up to 7 psi (0.5 bar)

• 3X for 15 to 600 psi (1 to 40 bar)

• 2X for ranges above 600 psi (40 bar)

Pressure Containment

Application of the following pressures may damage the transmitter but process media leakage will not occur

When intermediate ranges are required the core is selected to ensure that the thermal eects remain within specication after adjustment.

The transmitter provides an integral female pressure port and a range of screw-in stainless steel male to male adapters are available as options, mounted by a bonded seal supplied with the adaptor.

The detachable electrical and pressure connection formats allow the user to recongure or change these parts on site if they are damaged or an alternate location is required (conduit connections are not detachable).

Gauge Reference Versions

• 60 psi (4 bar) for ranges up to 9 psig (600 mbar)

• 150 psi (10 bar) for ranges up to 20 psig (1.4 bar)

• 5X rated pressure (2900 psi (200 bar) maximum) for

ranges above 20 to 900 psig (1.4 to 60 bar)

Absolute/sealed gauge reference versions

• 2900 psi (200 bar) for ranges up to 900 psia (60 bar)
