Name: BARTEC Hygrophil F 5674 Moisture Analyzer – Brochure & Quote
Brand: BARTEC

Description

Overview

The BARTEC HYGROPHIL F 5674 (HYF 5674) is a process trace moisture analyzer evaluation and control unit designed for continuous, reliable moisture measurement in industrial gas and liquid processing. It works exclusively with BARTEC’s optical L166x measuring sensors connected via fibre-optic hybrid cables.

Reliable trace moisture measurement is essential for process safety, product quality, and asset protection, and the 5674 delivers highly stable readings at very low moisture levels even under demanding conditions such as high pressure or hazardous areas.

Engineering & Design

The HYGROPHIL F 5674 performs signal evaluation of the Fabry-Pérot interferometer optical sensor using secondary optical principles, updating an averaged measurement result in less than 5 seconds for single-channel systems and under 15 seconds for full multi-channel updates.

Available as a single-channel or multi-channel unit supporting 1 to 3 sensor channels, the analyzer accepts interchangeable channel cards for analog current input with intrinsic safety [Ex ia IIC Ga], RTD input, and LED excitation [Ex op is] at 820nm, enabling safe operation with sensors in hazardous zones.

Measurement Range and Accuracy

Per BARTEC’s official product documentation, the HYGROPHIL F 5674 platform, evaluating its Fabry-Pérot interferometer L166x sensors, covers a calibrated dew point range of -80°C to +20°C (-112°F to +68°F) with an accuracy of ±1 K dew point, and can present the result in multiple engineering units — ppmv, ppmw, dew point, frost point, relative humidity, mg/m³, lbs/mmscf, and water vapor pressure — so the same measurement can feed different consumers (a DCS trend, a custody-transfer calculation, a regulatory report) in the unit each one requires without a separate conversion instrument.

Compatibility & Integration

The 5674 integrates into DCS and PLC environments via Modbus RTU or Modbus TCP/IP, with up to 8 freely assignable analog output channels carrying temperature, pressure, dew point, and PPMv/PPMw moisture values.

Selection Notes

Confirm whether your process needs single-channel or multi-channel evaluation, the specific L166x sensor variant matched to your process pressure and temperature, and whether the point requires the intrinsically safe [Ex ia IIC Ga] or optically isolated [Ex op is] channel card, since these determine both the correct HYGROPHIL F 5674 configuration and the compatible sensor part number. Seven Star LLC verifies these details against your process conditions before quotation to ensure the delivered system matches your measurement point exactly.

Engineered Support

Our process analyser specialists support sample conditioning design, L166x sensor selection, and DCS integration via Modbus, plus commissioning assistance from our engineers in Oman for gas processing and petrochemical projects.

Long-term support includes spare part planning for sensor caps, fibre-optic cables, and channel cards so your moisture measurement remains operational.

Operational Benefits

The HYGROPHIL F 5674 gives process engineers continuous, high-resolution trace moisture data that supports product quality control and protects downstream processes from moisture-related corrosion and hydrate formation.

Its fast update time allows operators to react quickly to changing process conditions, while multiple configurable output channels enable direct alarming and trending in the DCS.

Intrinsically safe channel cards expand the range of applications into hazardous areas without complex installation barriers.

For processes that need accurate trace moisture measurement, Seven Star LLC supplies the BARTEC Hygrophil F 5674 with engineering support, and our specialists configure each analyzer for your measurement point.

About brand

Explosion protection is the common thread in everything BARTEC makes. The company was founded in 1975 and is based in Bad Mergentheim, Germany, and its equipment is built to work safely where flammable gas or dust may be present.

Seven Star LLC lists BARTEC process analyzers, Ex enclosures, switching components and hazardous-area tablets, and supplies them to refineries, gas plants and panel builders in Oman by type number.

BARTEC product families on this page

The analyzer group is the largest. Under the HYGROPHIL name there are the HYGROPHIL F 5674 process trace moisture analyzer and the Hygrophil HCDT hydrocarbon dew-point analyzer. Under the BARTEC BENKE name there are the RVP-4 vapor pressure process analyzer and the P-600 salt in crude analyzer. The electrical side is represented by the GUB flameproof Ex d IIC enclosure and the 07-1511 series insert switch, a component used inside control stations. The Agile X IS is a tablet PC for Zone 1, and the EXguard is a mobile gas detection system for hot work.

Where BARTEC equipment is used

Moisture and hydrocarbon dew-point analyzers monitor natural gas at dehydration units, pipeline entry points and custody stations. Vapor pressure and salt in crude analyzers serve refinery blending and crude treatment. Flameproof enclosures and Ex switches go into local control stations, junction boxes and motor starters. Ex tablets are used for inspection rounds and work permits on GCC oil and gas sites.
