Detector Specifications - Toshiba LQ300A00 Series Operation Manual

Electrical resolution: 0.001%TS
Note 1: Resolution measured in a single unit.
Note 2: Verifiable resolution in the simulated reagent: 0.1%TS
The verifiable resolution value refers to the value which is verified through a test, of the
density difference which can be resolved as a density meter output. Marginal errors in
testing such as uneven density distribution and environmental variations, etc. are also
included in this value.
Ambient conditions: Temperature 0 to 50 °C
Structure: (Water resistance: JIS C 0920, IEC IP 65)
Note: Outdoor installation is also allowed. However, if the installation site may be exposed to
direct sunlight, keep the converter away from the sunlight by setting up a shade.
Vibration: The following vibration tests are performed without a problem.
(1) Applying vibration of a resonant frequency in 5 to 150 Hz range with acceleration of 4.9
m/s2 in x, y and z directions for 30 minutes each totaling 90 minutes. No deterioration of
performance or damage was found. Resonant frequency was 20 to 45 Hz (depending on
vibration direction).
(2) Applying vibration of 5 to 150 to 5 Hz with acceleration of 4.9 m/s2 for 3 minutes in each
direction and this is repeated 10 times for each direction totaling 90 minutes, and no
deterioration of performance nor damage was found.
Mass: Approx. 20kg
Maximum velocity: 5m/s (when viscosity is 1 Pa•s)
Note: When the viscosity level increases, the maximum velocity will be limited. Contact
Toshiba. (Example: In the case of 0°C water, 1.792 mPa•s)
Microwave transmission power: approx. 1mW
Note: This power is within the limit stipulated in the Radio Law. No license is required.
