* 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).


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.

*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);

*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.
