range, which is the upper limit setting range.

Resolution:

Meter size	50 mm (2”)	80 mm (3”)to
		300 mm (12”)
Resolution	0.002%TS	0.001%TS

Note 1: Above values are the results of commuting ability in the phase measurements of the converter.

Note 2: Density (consistency) determination resolution for sample reagent;

Meter size	50 mm	80 mm (3”)to
	(2”)	300 mm (12”)
Density(consistency)	0.1%TS	0.05%TS
determination repeatability

*The density (consistency) determination resolution stated above is defined due to manufacturing limitation to make reagents with stable distribution and a minimum difference of fluid density (consistency).

<Notice>

1.Install a sample tap near the LQ500 as close as possible to get an accurate density (consistency) measurement using the LQ500.

2.Take several samples in rapid sequence for more accurate density (consistency) measurement with less human error factors.

Environmental conditions:

Items	Temperature range	Humidity range
	Standard: 0 to 50 deg.C
Detector	(32 to 122 deg.F)	5 to 85%RH
	Option: -20 to 50 deg.C
	(4 to 122 deg.F) (*1)	(no condensation)
Converter	0 to 50 deg.C
	( 32 to 122 deg.F)

*1 A rubber heater is installed at the RF part of the detector.

Need to prepare an additional power supply either 100Vac type or 200Vac type for it by yourself. Determine one of them at the specification code. This option is available for detector only.

Structure: Converter;IP65,

Detector:IP67, Watertight

Note: Outdoor installation is possible. However, provide a sunshade for the converter section if direct sunlight is unavoidable.

Microwave power: 10 mW

Vibration resistance:

No resonance to the following levels of vibration:

(1)No failure for 5 to 150 Hz with the following acceleration in each device for 30 minutes in each axis of X, Y, and Z (90 minutes); Converter: 4.9 m/s2, Detector: 25m/s2

(2)No failure for 5 to 150Hz with the following acceleration in each device for 3 minutes in each axis of X, Y, and Z, 10 times (90 minutes as total);

Converter: 4.9 m/s2, Detector: 25m/s2

Note: Avoid using the LQ500 in an environment with constant vibration.

Cables: See the Table 2

*1 10m (32.8 ft) length is packed as standard.

*2 Need to prepare this cable by the customer.

*3 Need to use a sheathed cable.

*4 If the diameter of the cable is smaller than the inside diameter of the packing, enlarge the cable diameter to the same size as the packing by wrapping around the cable.

This dimension is coming from a diameter of the cable gland of the LQ500.
