Multifunctional
The THERMOFID is used in a variety of industrial applications, environmental measurement systems and R&D
projects. Typical use of the Thermo-FID are LEL control, flue/exhaust gas at waste incinerators or the petrochemical
industry, ambient air analysis, work place control MAK/TRK-limits and process control optimization.
Microprocessor for optimal control and operation
The microprocessor controlled Thermo-FID provides menu driven ‘clear text’ user friendly interface information on an
alphanumeric display. All operational and self diagnostic data are also available on RS232 and/or analog/digital
outputs (status alarm PCB, optional). A fully automated and continuous self diagnostic and log book entries for all
operation and calibration data guaranties an optimum analyzer up time.
The unique close couple detector design (no cables, etc.) provides a low drift
operation and a wide dynamic range with always optimum signal noise ratio. All
digital input feature are designed according NAMUR guidelines, all digital outputs
are potential free contacts. Analogue output signals are offered as standard 1x 0/420mA, 600 Ohm load (not galvanic isolated), optional 4 x 0/4-20mA optical galvanic
isolation is available on the status & alarm card. Instrument operation, configuration
and remote control is also available on 2 x RS232.
The measurement principle of the Thermo-FID is based on the ionisation of
hydrocarbons in a hydrogen flame. An exceptional constant sample gas flow and a
constant hydrogen stream are drawn to the burner nozzle which being on a negative
potential measured by the close coupled detector. In the temperature controlled
burning chamber, the mixture is burned by adding hydrocarbon free air in relation of
approx.10 : 1. The resulting ions are collected on a polarized electrode, amplified
and put to display
Best measurement performance is provided by offering a very constant

out. Flow controllers, sensors and valves get in contact only with
clean (compressed) air, hydrogen and span gas.
This in combination with the dilution of the sample gas with
compressed air as exhaust gas, results in an analyser with low
service costs and high availability..
Service
The modular design of the THERMOFID en the accessibility of
essential parts in the detector guarantee a simple service and
maintenance on-site. Specialists with decades experience on
analyser and sample-handling with FID´s will assist you with
advice and engineering, coordination of the system integration
and assistance before during and after start up.
