Toshiba Density (Consistency) Meter LQ500 - Manual (Page 4)

LQ500
4
hours when programming every 5
minutes.
• Moving average function:
In order to keep the average density (consistency)
output, or in order to suppress the deflection
width of the output. It helps for density
(consistency) control.
Enable to determine a number from 1 to 99.
• Change-rate limit function:
In order to reject the transient density
(consistency) output as noises, or a sudden
variation in the output according to intrusion by
bubbles, etc....
Allowable rate of change limit: 0.00 to 9.99%TS
Enable to determine a number from 0 to 99.
• Additive correction function:
Available for up to 10 kinds of mixed / blended
liquids. Sensitivity compensation can be set using
registered parameters depending on the type and
the mixing rate of liquids.
• Password function:
This function is used to limit access to changing
parameters that affect measured data by means of
a password.
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 LCD (dot-matrix)
with backlight.
Power supply:
100 to 240Vac 50/60Hz (Allowable voltage: 85 to
264Vac)
Note: 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.
Note2: UL/CUL Hazardous locations type does not
have a power switch. Please prepare a power
switch outside. (Rated 250V AC,10A above,
DPST: Double-Pole/Single-Throw)
Use the power switch for Hazardous
locations in Hazardous locations area.
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
