Safety Precautions
The D6F is built for use with general-purpose devices. In cases
such as those described below, where safety is required, implement measures to ensure the safety of the system and all
devices, such as fail-safe designs, redundancy designs, and regular maintenance.
• Safety devices for ensuring safety for persons
• Transportation equipment control (such as applications to stop
operation)
• Aviation and space equipment
• Nuclear power equipment
Do not use the D6F for applications in which D6F operation
would directly affect human life.
Caution
Make sure that the power to all equipment is turned OFF before
you install the Sensor. Installing the Sensor while the power supply is ON may result in electrical shock or abnormal operation.
Precautions for Correct Use
● Fluids, Tubes, and Sensor Installation
All Models
(1) Use clean fluids. Dust and mist can affect the characteristics
of the Sensor or damage the Sensor. Install a filter and mist
separator on the upstream tube.
(Not required for the [email protected], D6F-V, D6F-P and D6FPH.)
(2) Do not use combustible gases (e.g., hydrogen), corrosive
gases (e.g., chlorine, sulfur, acidic, or alkali gas), or other
non-approved fluids. They may damage the Sensor.
(3) The performance specifications that are given for the G6F
do not apply if any fluids other than the specified applicable
fluid are used.
(4) Foreign matter in the tubes that are connected to the Sensor
may damage the Sensor. Prevent any foreign matter from
entering the tubes after the Sensor is removed from its
packaging.
(5) Attach the tubes so that fluid flows only in the direction designated by the arrows on the Sensor. Correct measurements
cannot be obtained if the fluid flows in the wrong direction.
(Not required for the [email protected], D6F-V, D6F-P, D6F-PH.)
(6) We recommend that you install the tubes horizontally. If the
tubes are not installed horizontally, an error of ±1% F.S. or
higher may result. (This does not apply to the D6F-03A3.)
(7) Install the Sensor on a flat surface. Incorrect installation may
damage the Sensor and make it impossible to obtain correct
measurements.
(8) After the Sensor is installed, check to confirm that it operates correctly.
(9) Do not drop the Sensor, remove the cover, or attempt to disassemble the Sensor in any way.
(2) Do not apply big force to piping which remain to join, and not
apply big force directly to joint part with gripping case. It
causes defective leakage and breakage.
*Reference
There is a possibility that leak damage or faulty of the body
occurs when static load of more than 40N is applied to 300
mm from the center of product as fulcrum point.
● Operating Environment
Do not use the Sensor in the following locations:
• Locations directly subject to heat radiated from heating equipment
• Locations subject to water or oil
• Locations subject to direct sunlight
• Locations subject to intense temperature changes
• Locations subject to icing or condensation
• Locations subject to excessive vibration or shock
● Countermeasures against Noise
Noise may make it impossible to obtain correct measurements.
Consider the following countermeasures.
• Allow as much space as possible between the Sensor and
devices that generates high frequencies (such as high-frequency welders and high-frequency sewing machines) or
surges.
• Attach surge absorbers or noise filters to noise-generating
devices that are near the Sensor (in particular, equipment with
inductance, such as motors, transformers, solenoids, and
magnetic coils).
(It also helps to separate pipes and ducts, and to use shielded
cables.)
● Power Supply
• Wire with the correct terminal names and polarities. Incorrect
wiring will cause failure of internal components.
• When using a commercially available switching regulator,
ground the FG (frame ground) and G (ground) terminals.
RoHS Directive
The RoHS mark is displayed on the packing of products for
which the six substances banned by the RoHS Directive have
been abolished (both in processing and in the electronic components mounted to the PCBs).
*
RoHS marking may be terminated if it is later determined that parts that were
previously treated as RoHS compliant are not compliant due to circumstances at the supplier of the parts.
● RoHS Compliance Criteria
The following standards are used to determine RoHS compliance for the six banned substances.
(Items to which the RoHS Directive is not applicable are not
given.)
• Lead: 1,000 ppm max.
• Hexavalent chromium: 1,000 ppm max.
D6F-@@@7
• Mercury: 1,000 ppm max.
(1) Please use a Quick Joint (Type P10) for piping, and fix it by
a Quick Fastener that fit Type P10.
• PBB: 1,000 ppm max.
• Cadmium: 100 ppm max.
• PBDE: 1,000 ppm max.
