| SYSTEM 4 INFRARED THERMOMETER SIGNAL PROCESSORS |
| |
LANDMARK® infrared thermometer signal processors are designed to produce the process control variables you need from ANY of the SYSTEM 4 infrared thermometers. With this total compatibility, you are free to choose a processor to give the features and performance that are best suited to your application.
All SYSTEM 4 processors and thermometers are calibrated individually to guarantee interchangeability and hence easy maintenance for many years.

| LANDMARK GRAPHIC |
| |
 |
|
LANDMARK® GRAPHIC is a high precision, multi function, intelligent infrared thermometer signal processor with graphical display. Two versions are available: a single channel and a multiple channel processor.
The multiple channel version can be configured with up to four different thermometers. A simple to use multi-language menu enables the user to set-up the thermometer and process variables.
LANDMARK® GRAPHIC provides a complete range of thermometer signal conditioning functions including: peak picker, averager, track and hold, high/low alarms and 0 or 4 to 20mA and 1mV/° outputs from each thermometer channel.
Temperature is displayed as a deviation chart, line chart, numeric or mixed display.
Optional serial RS232C/RS485A communications is also available.
|
| |
|
|
A new math function is available which simultaneously computes and outputs two additional values including: maximum, minimum, mean, difference, range and expanded span. Typical examples include: monitoring the temperature uniformity across a web or strip using an array of 4 thermometers; expanded span which combines the minimum and maximum temperature ranges of up to 4 different thermometers; and difference where two thermometers are monitoring the same target spot.
