Provide process control variables to improve quality and efficiency
System 4 LandMark Graphic, 4 channel signal processor
Landmark Processors are designed to produce the process control variables you need from ANY of the System 4 thermometers. With this total compaitibility, you can choose a processor which provides the features and performance you need to meet the requirements of your application.
All thermometers and processors are calibrated individually to guarantee interchangeability and hence easy maintenance for many years

Landmark Graphic
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 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.
Landmark PROFIBUS
LANDMARK® for Profibus is a high precision, digital, DIN-rail mounted signal processing unit, providing economic integration of any System 4 thermometer within a Profibus network – ideal for both OEM and end user applications.
LANDMARK® for Profibus (LMP) is an intelligent microprocessor-based thermometer signal processor, designed for the ultimate in process temperature monitoring at low cost.
A complete range of thermometer signal conditioning functions is provided including: peak picker, averager, track and hold, and alarm outputs. As well as its standard Profibus DP interface, LMP also provides additional analog connectivity for supplementary process integration via a 0 or 4 to 20mA output with user-selectable span, Hi/Lo alarm contacts and external control of peak-picker reset or track & hold reset via customer contact closure.
