Humidity: 5 to 90%RH (No condensation)
Structure: Detector Immersion-proof type (IP67: Immersion-proof type or equivalent)
Converter Waterproof type (IP65: Waterproof type or equivalent)
Note: Outdoor installation is possible. If there is a possibility of direct sunlight, however,
provide a sunshade to the converter to avoid direct sunlight.
Vibration: (1) Applying vibration of a resonant frequency in 5 to 150 Hz range in x, y and z
directions for 30 minutes each totaling 90 minutes, and no deterioration of
performance nor damage shall be found.
However, acceleration is as follows:
•
Detector: 25m/s2
•
Converter: 4.9m/s2
(2) Applying vibration of 5 to 150 to 5 Hz with the acceleration shown in (1) above for
3 minutes and this is repeated 10 times for each direction of vibration totaling 90
minutes, and no deterioration of performance nor damage shall be found.
Altitude : Up to 2000m
Mass: Refer to the Attached Figure 1, “Dimensions” in “Appendix.”
Microwave transmission power: Approx. 10W

Note: Precautions about measuring fluids
When measuring density in liquids containing conductive particles such as the carbon
particles of activated carbon or metal powder, density measurement may be affected by
