4 / 6 page 4 D6F-P MEMS Flow Sensor Safety Precautions The D6F is built for use with general-purpose devices. In cases such as those described below, where safety is required, imple- ment measures to ensure the safety of the system and all devices, such as fail-safe designs, redundancy designs, and reg- ular 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. Make sure that the power to all equipment is turned OFF before you install the Sensor. Installing the Sensor while the power sup- ply is ON may result in electrical shock or abnormal operation. ● 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 D6F-W@A1 or D6F-P.) (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 des- ignated by the arrows on the Sensor. Correct measure- ments cannot be obtained if the fluid flows in the wrong direction. (6) We recommend that you install the tubes horizontally. If the tubes are not installed horizontally, an error of ±1% FS 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 oper- ates correctly. (9) Do not drop the Sensor, remove the cover, or attempt to dis- assemble the Sensor in any way. D6F-P0001A1, D6F-P0010A1, and D6F-P0010A2 (1) Depending on the ambient environment and installation location, dust, dirt, and other foreign matter may come in inside the Sensor and block a part or all of the flow path or accumulate on internal components. This may result in the Sensor not being able to perform to the specifications given above. Always perform a pre-evaluation on your actual equipment and be aware of the possible problems that may occur before you use the Sensor with the actual equipment. (2) Attach all tubes so that the fluid flows only in the direction from the positive side ( +) to the negative side (−). (3) For PCB-mounting, perform terminal soldering only after the Sensor is secured into place on the PCB. (4) Use M2.6 panhead screws or equivalent tapping screws to mount the Sensor, and tighten the screws to a maximum torque of 0.59 N·m. D6F-P0010AM2 (1) Depending on the ambient environment and installation location, dust, dirt, and other foreign matter may come in inside the Sensor and block a part or all of the flow path or accumulate on internal components. This may result in the Sensor not being able to perform to the specifications given above. Always perform a pre-evaluation on your actual equipment and be aware of the possible problems that may occur before you use the Sensor with the actual equipment. (2) Attach all tubes so that the fluid flows only in the direction from the positive side ( +) to the negative side (−). (3) Use M3 panhead screws or equivalent tapping screws to mount the Sensor, and tighten the screws to a maximum torque of 0.59 N·m. (4) Install O-rings to seal the fluid inlet and outlet points. The recommended O-ring is JIS B 2401, nominal number P4. ● Operating Environment Do not use the Sensor in the following locations: • Locations directly subject to heat radiated from heating equip- ment • 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 • Do not directly solder power supply leads to the connector ter- minals. Use only the appropriate connectors. • 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. WARNING Caution Precautions for Correct Use O-ring M3 panhead screw or a tapping screw with the same diameter Installation Example |
