• Moving average function: 

In order to keep the average density (%TS, 
consistency) output, or in order to suppress the 
deflection width of the output. It helps for density 
(%TS, consistency) control.  

<Specification> 

Enable to determine a number from 1 to 999.  

• Change-rate limit function: 

In order to reject the transient density (%TS, 
consistency) output as noises, or a sudden 
variation in the output according to intrusion by 
bubbles, etc....  

<Specification> 

Allowable rate of change limit: 0.00 to 9.99%TS 

Enable to determine a number from 0 to 99.  

• Additive correction function: 

Capable of handling up to ten brands, this 
function performs the sensitivity correction 
appropriate to the additives type and compound 
ratio in accordance with the parameters that are 
registered in advance.  

• Password function: 

This function is used to limit access to changing 
parameters that affect measured data by means of 
a password. 

• Number of Rotation N fixed function: 

This function is used to fix the number of angle 
rotation N when the external synchronized 
operation starts. 

 (LQ500 measure the phase of microwave, and 
calculate the density/%TS from the phase changes.  

Because the phase is limited from 0 degree to 360 
degrees, LQ500 use the rotation N when the phase 
is over 360degree. But the range of density is wide 
over the 360 degree, LQ500 may not know the 
number of the rotation N when the pump starts. If 
the density is constant when the pump starts, 
LQ500 can set the number of rotation N, and 
measure the correct density(%TS, consistency). 

 

Arrestor: 

Arrestors are installed in the LQ500 current output 
(4-20mAdc) and AC power lines. 

 

Operation panel and Display: 

Used to check data or change various settings. 

Operation switches: 5 switches.  

Display: 4-line, 20-character VFD(dot-matrix

)

  

Power supply: 

100 to 240Vac 50/60Hz (Allowable voltage: 85 to 
264Vac) 

Note1: An additional power supply is required when 

choosing an optional environmental temperature 
specification type (-20 to 50 deg.C). 
Refer to the section of Environmental conditions in 
detail.  

Power consumption:  

Approx. 25VA (100Vac), Approx. 35VA (240Vac) 

Housing material: Steel plate 

Coating: Polyurethane 

MTBF: 135.8 months under 25 deg. C (77 deg. F) 

based on MLL-HDBK-217F
