Omron K3HB-S DATASHEET

Linear Sensor Indicator

K3HB-S

Visual clarity and instantaneous measurement.
Control status and judgement results can be ascertained
at a glance using the display color and position meter.

Features

■ Intelligent

● High-speed Response at 2,000 Times per Second

Capable of high-speed sampling at 2,000 times/second.
Peak-hold and bottom-hold functions allow accurate mea­surement of peak and bot t om values.

● Calculations Based on T wo Input Signals

Calculations, such as K−A, A+B, A−B, and K−(A+B), can be
performed on two analog input signals. This enables highly
precise thickness and level-difference measurement. The
input ranges can be set independently so, for example, sig­nals between 4 and 20 mA can be han dl ed by one input w hi le
signals between 1 and 5 V are handled by the other.

● Red-Green Display Allows Easy Recognition of Judg-

ment Results

The measurement value display can be set to switch between
red and green in accordance with the st atus of comparative
outputs. This means t hat the status can be ascertained at a
distance.

● Position Meter Enables Easy Monitoring of Operating

Status Trends

The present value with respect to the measurement or display
range (full scale) can b e v iewed on a b ar di splay. This means
that the operating status can be grasped intuitively, allowing
easy judgement of levels and threshold values.
