Raytek® Marathon MM
More Performance for a Broad Range of Applications
- Document your process control with real-time video monitoring and recording capability
- Ensure the integrity of the measurement with instant noncontact temperature readings
- Easily configure each sensor with Remotely Adjustable Precision Variable Focus
- Improve validation of correct aiming with integrated visual and laser sighting
The Raytek MM Sensors are rugged, NEMA 4 sealed single-piece systems with easy-to-use operator interface and the flexibility to handle nearly any application.
The Marathon MM series platform consists of five IR temperature sensor models, each with a measurement wavelength and temperature range appropriate for specific application needs, from low temperature plastic processing to high temperature glass and metals processing.
The Marathon MM features Precision Variable Focus that allows fast, easy and accurate adjustment of the focus of measurement targets, either by push-button at the rear of the instrument or remotely via an RS232/RS485 PC connection, where adjustments can be seen in real-time through video. Sensors with variable focus option can be configured according to specific application requirements, reducing the installation time and chance for incorrect installation.
The optional video sighting allows for simultaneous visual and temperature process monitoring, with the capability to capture and document any process variations. This unique capability sets a new standard for process monitoring.
Through the lens and laser sighting come standard on every unit, and optional integral video make the MM unit easy to install and operate.
All sensors feature identical installation hardware and include Raytek DataTemp Multidrop software to enable easy and consistent installation, configuration and data capture across the full breadth of an applications.
