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 offering both flameproof/ explosion-proof or dust ignition protection by enclosure capability as required. Intrinsic safety options are also available. They provide a lightweight and cost effective 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, ourfield-proven Druck silicon technology is at the heart of the new platform, resulting in a range of high quality, high stability pressure sensors.
•Accuracy to ±0.04% Full Scale (FS) Best Straight Line (BSL)
•Stainless Steel construction
Bespoke as Standard
Custom-built from standard components, manufacturing sensors to yourrequirement 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 yourneeds foraccurate and reliable product performance; ourteam of experts can help you make the right sensorselection, 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 foryour application.
•Integrated terminal compartment with long or short body (5900)
•Frequency response to 3.5 kHz
•High overpressure capability
•Hazardous Area certifications

^ with a 10 volt supply mV output sensors give 100 mV overthe full scale pressure. Output is ratiometric to the supplyvoltage.
*0 to 5 V 3-wire output is non true zero. At pressures below 1% of span the output will be fixed at approximately 50 mV
**32 V maximum fornon-hazardous area operation
~Supplyvoltage is between [Maximum Output + 1V] (7 V minimum) to 16 V (32 V in non-hazardous area operation)

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).
ShuntCalibration(5800only)
Shunt calibration provides a customeraccessible connection which, when applied, causes a shift in output of 80% FS in orderto simulate applied pressure. It is fitted to the mVversion as standard. Shunt calibration is activated by connecting Shunt Cal to -ve Supply.
