Typical Applications
| Product Material |
Length, width, level and
position of hot or cold product. |
| Metals
Industry |
Measure/position slab, billet,
bloom or bar, automatic cutoff, coil diameter and level in a
crucible, ladle or vessel. Laser measurement of length, width,
level and position of product. Tracking of Hot product inside or
around a furnace. |
The MDHD20HT Laser Distance Meter
operates via a unique pulsed time-of-flight (TOF) measurement technique
and measures distances off of a red hot glowing natural surfaces up to
1400°C (2552°F) at distances of up to 20 meters. The MDHD20HT transmits
ultra-short light pulses at the rate of 1000 measurements per second,
measures the TOF to the reflector and back to derive the distance and
transmits this data information via an interface to a computer, PLC or
an analog instrument. |
|
The MDHD20HT is equipped with a
powerful m-Processor to handle a variety of measurement tasks and self
diagnostics. By means of parameterized mean value calculation, high
dynamic positioning tasks may be accomplished.
Two programmable threshold bands can be defined. Measurements below
these thresholds are indicated via digital outputs & LEDS. These
thresholds & outputs are programmable via a RS232 or RS422 connection to
a computer or a PLC. The MDHD20HT is equipped with a switch selectable
opto-coupled RS 232, RS422 & programmable analog interface as standard.
Only one digital output is available if the analog interface is
selected. An optional PROFIBUS DB Interface is also available. |
