The MODLINE 3 Series features a broad line of infrared thermometers to match specific applications in many industries. The system offers you the choice of temperature sensors with sophisticated single lens reflex (SLR) focusing that can view spots as small as 0.012 inches (0.3mm), or infrared sensors using two color (ratio) technology to tolerate more than 95% reduction in radiant intensity, or fiber optic sensors for difficult to reach or obstructed targets.

The MODLINE 3 Indicator/Processor consists of a high performance sensor and microprocessor-based digital Indicator/Processor. Many standard features are included and only a two-point On/Off controller/alarm or a PID controller are optional. Additionally, Ircon offers standard accessories to meet the demanding environmental requirements you may have, such as air purge and water cooling, sight tubes and mounting assemblies.

MODLINE 3 utilizes advanced microprocessor technology to process highly accurate temperature signals received from the temperature sensor. This data is accurately displayed on a highly visible LED digital display in °F or °C. Programming features and control functions are viewed on a bright, highly readable Alpha Numeric, Vacuum Fluorescent display.

MODLINE 3 Indicator/Processor
The MODLINE 3 Indicator/Processor is a compact, self-contained, microprocessor based signal processor and display designed for simple installation, operation and service.

The instrument is designed to operate with all MODLINE 3 temperature sensors and provides the input power to operate the sensor. Temperature signals from the sensor are displayed on a large visible, 0.8 inch (20.5 mm), LED display in °F or °C. MODLINE 3 offers you three standard selectable isolated analog output signals; 4 to 20mA, 0 to 20mA and 5µA per degree for your analog process control instruments. The analog outputs are adjustable to cover any portion of the instruments available temperature span to a minimum of 50° C or F. A standard RS-485 digital signal output is available for two-way digital communications for your digital process control instruments.

MODLINE 3 provides as standard features a complete range of signal conditioning functions, including Emissivity/E Slope, Track and Hold, Peak Picker and Response Time. Optional features offered are On/Off Controller or PID Controller.

The MODLINE3 Indicator/Processor includes a large LED display dedicated for temperature display and a smaller alpha numeric vacuum fluorescent digital display that is dedicated for displaying menu and control function inputs. Set-up and operation are easily configured using a four button keypad.

TEMPERATURE SENSORS

The MODLINE 3 system offers you the widest choice of non-contact infrared sensors to match any process. MODLINE 3 sensors offer sophisticated single lens reflex (SLR) focusing, that can view spots as small as 0.012 inches (0.3 mm); or for difficult, high temperature and harsh environments, some model series incorporate fiber optics for added flexibility. These rugged, high performance infrared sensors feature through-the-lens sighting of target, incorporating a circular reticle visible through the eyepiece that defines the exact spot to be measured.

The optical system, detector and electronics are housed in a rugged sealed casting rated NEMA 4 (IP66), to perform in the harsh industrial environments. MODLINE 3 sensors are designed to match existing mounting configurations and offer a choice of cooling and environmental protection accessories.
