Precautions
1. Avoid use in excessively dirty, wet environments
2. Do not use in the presence of flammable gases (e.g. hydrogen, methane, ethane and liquefied petroleum gas. In addition, do not use with
corrosive gases (eg chlorine, sulphur, acids, alkalis etc).
3. Install in the direction of the arrow indicated.
4. For best results (optimum accuracy), mount horizontally.
5. Use suitable M3 screws for mounting. Do not exceed a fixing torque of 0.59 Nm.
6. Do not modify D6F- in any way.
7. Do not place any object in or close to the inlet and outlet orifices.
8. Do not use the sensor in any of the following environments:
- a location that receives radiant heat from the sun or apparatus
- a place where intense light may radiate down
- where fast changing temperatures occur
- locations prone to freezing, high humidity, condensation
- places where large magnitudes of vibration or shock could occur
9. Noise countermeasures: VERY IMPORTANT: Take suitable precautions to minimise the effects and potential for induced electrical noise. Install
away from apparatus that generates strong high frequencies, surges and spikes. Take particular care to install away from AC power
transformers, live mains power lines and high power magnetic circuits. Attach a surge suppressor and a noise filter to the peripheral equipment.
10. Ensure good grounding is achieved by grounding the GND terminal to the peripheral equipments main ground frame connection and its
associated regulated power supply.
11. Do not make a direct solder connection to the integral terminals. It is recommended you use the optional cable ‘D6F-CABLE2’ for attachment
and to ensure correct connection.
12. D6F- is a precision component. Keep in original packaging and remove only when ready for installation. Damage may occur if subjected to
excessive force (e.g. dropped or kicked). Any item suspected to be damaged should be discarded.
13. Immediately following installation, a qualified person should perform checks to ensure safe, satisfactory operation.
Note 1: Air velocity. D6F-V is optimally adjusted for air velocity detection, derived from mass air-flow measurement according to air
in-house test method using a wind tunnel phi 48 mm.
