Installation environment
To ensure the stable use of the HU-200SS SS-90 condition, install the HU-200SS SS-90 in a
location that meets the following requirements.
Q
Instrument mainframe
z
The location should be well ventilated to prevent build-up of moisture.
z
The ambient temperature should be between
−
20
°
C and 55
°
C.
z
The HU-200SS SS-90 should not be exposed to direct sunlight.
z
The HU-200SS SS-90 should not be exposed to direct high radiation heat.
z
The relative humidity should be 90%
or lower.
z
The HU-200SS SS-90 should not be exposed to splashed water or chemical agent.
z
The mechanical vibration in the location should be minimal.
z
The location should have adequate space to allow maintenance and wire connecting
work.
z
The location should be free from dust and corrosive gas.
z
The location should be minimally affected by an electromagnetic fields.
z
The altitude should be no more than 2000 m.
z
The range of fluctuations in supply voltage should be within 100 V to 240 V AC
±
10%.
Q
Detector
z
The location should have adequate space to allow for checking and maintenance of the
detector.
z
Spilled water should not adversely affect the location.
z
Utilities should be made available for zero water.
z
Measured liquids should be those that will not damage the portion of the detector that
comes into contact with the liquid.
z
The solution being measured should be free from air bubbles.
z
Measured liquid should be adequately agitated to be uniform.
z
If measured liquid is aerated, air bubbles do not directly come in contact with the detector.
Note
If measured liquid flows in only one direction, install and orient the sensor head to the downstream
side.
