M-Series

For Non-Contact Infrared
Temperature Measurement

Linear Laboratories M-Series line of non-contact infrared sensors are designed to provide accurate, continuous temperature measurement in a wide variety of manufacturing settings. As with all of our infrared
temperature instruments, the M-Series measures surface

temperature without contact by collecting infrared radiation (heat) from a remote object and focusing it on a detector. This infrared detector converts the radiation to an electrical signal which is amplified to produce a 0-1VDC non-linear output. There are many inherent advantages to using infrared technology for temperature measurement:

	Moving objects are measured easily and accurately.
	Dangerous or hazardous materials are measured safely, with no contact.
	Accuracy is assured because no heat is removed from the object being measured.
	Measurements are made rapidly so that thermal patterns and transient phenomena can be observed even on the fastest moving process lines.

	Adjustable Emissivity Compensates for Surface Conditions
	Small Rugged Packages
	Choice of Mounting Configurations for Easy Installment on Any Process Line
	Fast Response
	Choice of Outputs: Current, Voltage or Thermocouple Equivalent
	Maintenance-Free, No Moving Parts

The M-Series Sensors

The rugged miniature design of the M-Series makes them ideally suited for industrial environments where cost and size requirements are a consideration. With the wide choice of sensor packages, mounting configurations and temperature ranges, M-Series instruments can be implemented in virtually any industrial application. Adjustable Emissivity allows you to compensate for almost any surface condition (i.e. shiny, oxidized, painted, etc.). In addition, the M-Series Sensors and Linearizer/Power Supply units are readily adaptable to process machinery and compatible with standard temperature controllers. This means that our high reliability infrared sensor can easily replace the fragile, slow response, short-life thermocouples you may be using now.

M-Series AC-DC Powered Linearizer Units

Linear Labs' flexible M-Series products can be used as "stand alone"
units, providing a non-linear 0-1 VDC output, or they can interface with
a DC-powered M-200 or an AC-powered M-250 linearizer.

The Model M-200 DC Powered Linearizer and the M-250 AC Powered
Linearizer units are compatable with any of the M-Series Models. These
linearizers accept the non-linear signal input and produce a linear
output. The outputs available include 0-5VDC, 4-20 mA or Type J
thermocouple equivalent.

The M-250 is housed in a rugged aluminum enclosure. The enclosure is available seperately for the M-200 under part number ME-200.
