PDCR 4000 Series

The Druck PDCR 4000 Series, a range of high

performance millivolt output pressure

transducers, is a continuation of a successful

family of products started in the early

1970’s. This new generation of transducers

offers enhanced levels of measurement

accuracy, stability and reliability with a

flexible specification to meet the varied and

demanding needs of today’s industrial and

OEM users.

At the heart of each transducer are the latest

advances in micro-machined silicon diaphragm

technology from Druck’s own class 100 silicon

processing facility. The pressure sensitive

silicon element is mounted within a high

integrity glass-to-metal seal and is fully isolated

from the pressure media by a Hastelloy

isolation diaphragm, which is electron beam

welded in front of the seal.

Packaged with conditioning electronics into a

Hastelloy and stainless steel enclosure for

optimum corrosion resistance, the PDCR 4000

is compact, rugged and able to operate reliably,

even in the most hostile environments.

Large quantities of PDCR 4000 sensor “cores”

are produced and held in stock. These are then

selected and completed with pressure and

electrical connections to meet individual

customer requirements. This partially built core

concept ensures flexibility of choice, while

maintaining a short delivery. Additionally, every

core is fully tested over its complete pressure

and temperature range to ensure one hundred

percent compliance.

The high performance PDCR 4000 is ideally

suited to meet the demands of a wide range of

applications, particularly in harsh operating

environments where:

• accuracy

• stability

• reliability

• overpressure

• choice of specification

are important selection criteria, together with

quick delivery.

and 500 psi differential

Other pressure units can be specified e.g. millibar,

bar, kg/cm2, KPa, etc.

Overpressure

The operating pressure range may be exceeded

by the following multiples with negligible effect

on calibration.

PDCR 4000

Gauge and absolute:

10 x for ranges 1 to 2 psi

6 x for range 5 psi

4 x for ranges 10 psi to 900 psi up to maximum

of 2000 psi

2 x for range 1000 through 10,000 psi to a

maximum of 15,000 psi

PDCR 4100

Differential (positive side):

10 x for ranges 1 and 2 psi

6 x for range 5 psi

4 x for ranges 10 to 300 psi

3 x for range 500 psi

Differential (negative side):

6 x for ranges 1, 2 psi

4 x for range 5 psi

2 x for ranges 10 to 75 psi

150 psi for ranges 100 to 500 psi

This overpressure capability can be further

improved by selecting a range higher than

required and operating with a lower output.

Pressure Containment

Gauge and differential (positive side):

12 x for ranges up to 5 psi

6 x for ranges 10 to 900 psi (3000 psi maximum)

Differential (negative side):

8 x for ranges up to 5 psi

4 x for ranges 10 to 500 psi

200 psi maximum for ranges 100 to 500 psi

Sealed gauge and absolute:

3000 psi for ranges up to 900 psi

20,000 psi for ranges 1000 psi and above

Pressure Media

Fluids compatible with Hastelloy C276 and

stainless steel 316L.

Line Pressure

1000 psig maximum

Excitation Voltage

10 Volts at 5 mA nominal.

For pulse powered operation, the recommended

power-on time is 10ms before sample.

Output is ratiometric to supply within the

following limits:

1 V to 12 V for ranges up to 900 psi

5 V to 12 V for ranges 1000 psi and above

Output Voltage

(based on 10Vdc excitation)

50 mV for ranges 1, 2 and 5 psi

100 mV for 10 psi and above

Transducers with ranges up to 900 psi can be

over ranged 2 x Full Scale to provide up to

200mV output. Linearity is slightly degraded

but stability is improved.

For higher outputs up to 10 V refer to PMP 4000

series datasheet.

Common Mode Voltage

supply at 10 V excitation.

Stability

lower pressure range in the overrange

condition at a reduced excitation voltage.
