Precautions for Correct Use

Sensor Applications

The D6F is built for use with general-purpose devices. In particular, when using the D6F for applications with the safety requirements described below, take steps to ensure system and device safety through measures such as fail-safe designs, redundant designs, and regular inspections.
•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.

Fluids, Pipe Mounting and Sensor Installation

All D6F Models
(1) Use clean fluids. Install a filter or mist separator on the inflow pipe. Failure to do so may result in malfunction or changes in characteristics due to dust or mist. This does not apply to the D6F-W, D6F-V, D6F-P and D6F-PH.
(2) Do not use corrosive gases other than the specified applicable fluids (such as chlorine, sulfur, acid,or alkali) . Doing so may cause product failure.
(3) The specified performance may not be obtained if the D6F is used for fluids other than the specified applicable fluids.
(4) After removing the Sensor from the package, do not allow foreign particles to enter the piping. Foreign particles in the piping may cause product failure.
(5) Install the Sensor so that the fluid flows in the direction indicated by the arrow on the Sensor. Correct measurements cannot be obtained if the fluid flows in the wrong direction. This does not apply to the D6F-V, D6F-P and D6F-PH.
(6) It is recommended that the Sensor (except for the D6F-A3) be mounted horizontally. If it is not mounted horizontally, an error of ±1% FS or higher may result.
(7) Install the Sensor on a flat surface. Incorrect installation may damage the Sensor and make it impossible to obtain correct measurements.
(8) 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.
(9) Always check operation after installation.
(10) Do not drop the Sensor or disassemble the cover.

D6F-A7/-L7/-N7/-A7D/-AB71/-AB71D
(1) Use male quick couplings for the piping, and secure them with the applicable quick fasteners.
(2) Do not apply excessive force to the adapter section when connecting the pipes. If strong force is applied to the connected pipes, or if strong force is applied directly to the adapter section while holding the Sensor, it may damage the Sensor or cause leakage.
Installation Example
Use male, P10-type quick-connect joints for the D6F-A7/-L7/-N7/-A7D and P14-type quick-connect joints for the D6F-AB71/-AB71D.

Note. There is a possibility that leak damage or faulty of the body occurs when static load of more than 40 N 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

•Force of connector terminal is 20 N max. Do not add strength more than tension of wire bending to connector at wiring. Install the connector coaxially to the fitting axis with holding all wires. And pulling angle should be within 15 degrees.
•Use the applicable connectors. Directly soldering the connection terminals will cause product failure. (except for the D6F-PH)
•Check the terminal names and polarity and wire the power supply correctly. Incorrect wiring will cause failure of internal components.
•When using a commercially available switching regulator, ground
the FG (frame ground) and G (ground) terminals.
 

Handling

The sensor is a precision device, and if large shock and load is applied, it may cause a failure or characteristic change. Please do not use the sensor which is added excessive shock to the terminals, discompose the cover, or has fallen.
•The sensor shall only be handled in electrostatic discharge protected areas (EPA) under protected and controlled conditions
 

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.
•Mercury: 1,000 ppm max.
•PBB: 1,000 ppm max.
•Cadmium: 100 ppm max.
•PBDE: 1,000 ppm max.
