Druck UNIK 5800, UNIK 5900 Specifications

UNIK 5800/5900

Flameproof/Explosion-Proof
Pressure Sensing Platform

The 5800 and 5900 are compact and rugged versions
of the high performance UNIK 5000 pressure sensing

platform oering both ameproof/ explosion-proof
or dust ignition protection by enclosure capability as
required. Intrinsic safety options are also available.
They provide a lightweight and cost eective
alternative to pressure gauges and switches in
process and in oil and gas industry applications.

High Quality

Features

• Ranges from 2 to 700 bar (30 to 10000 psi)

With 35 years of pressure measurement experience,
our eld-proven Druck silicon technology is at the
heart of the new platform, resulting in a range of
high quality, high stability pressure sensors.

Bespoke as Standard

Custom-built from standard components,
manufacturing sensors to your requirement is fast
and simple; each UNIK 5000 is a “bespoke” pressure
sensing solution, but with the short lead times and
competitive pricing you would expect from standard

products.

Expertise

We have the people and the knowledge to support
your needs for accurate and reliable product
performance; our team of experts can help you make
the right sensor selection, guiding you and providing
the help and tools you need. It is important that you

ensure that the sensor materials and performance

selected are suitable for your application.

• Accuracy to ±0.04% Full Scale (FS) Best
Straight Line (BSL)

• Stainless Steel construction

• Integrated terminal compartment with long

or short body (5900)

• Frequency response to 3.5 kHz

• High over pressure capability

^ with a 10 volt supply mV output sensors give 100 mV over the full
scale pressure. Output is ratiometric to the supply voltage.

*0 to 5 V 3-wire output is non true zero. At pressures below 1% of
span the output will be xed at approximately 50 mV

**32 V maximum for non-hazardous area operation

~Supply voltage is between [Maximum Output + 1V] (7 V minimum) to

(Option 5)

Minimum span: 4 V

Maximum span: 10 V

Maximum output limit: 11 V

Maximum zero oset: Span / 2

Output voltage range can be specied to a resolution of 0.1 V

Not true zero, the output will saturate at < 50 mV

The output will continue to respond to 110% FS. i.e. if a 0 to
10 V output is specied, the output will continue to increase
proportionally to applied pressure until at least 11 V.

Examples

Supply Sensitivity

±0.005% FS/Volt (voltage and current version only)

Power-Up Time

• mV, voltage and current versions: 10 ms

Insulation Resistance/Isolation

• 500 Vdc: ≥ 100 MW

• 500 Vac: ≤ 5 mA leakage current

(mV and mA versions only).

Shunt Calibration (5800 only)

Shunt calibration provides a customer accessible
connection which, when applied, causes a shift in
output of 80% FS in order to simulate applied pressure.
It is tted to the mV version as standard. Shunt
calibration is activated by connecting Shunt Cal to -ve
Supply.
