Summary Products

Rugged design, designed for reliability, multichannel fiber optic temperature monitor for Industrial and Laboratory applications.

  • Rugged, Compact Design
  • 2 to 8 Channels, Expandable 
  • Plug and Play
  • Best in class EMI, ESD Immunity
  • Software designed to be interfaced with other testing platforms


The Rugged Monitoring L201 is a compact design, designed for reliability to operate in extreme EMI, RFI, Microwave and high voltage environments. The L201 Fiber optic monitor combines reliability and user friendly interface in the monitor and software.  It is a multi-channel fiber optic temperature monitor with precision measurement for Industrial and Laboratory applications. The L201 has a measuring range from -271 °C to +300 °C. The system o􀀀ers complete immunity to RFI, EMI, microwave radiation, and High Voltages  making it an optimal choice  for environments where the limitations of conventional temperature sensors/ monitors impact usage in extreme conditions. The system is based on proven GaAs technology  and designed for Plug and Play operation.

The L201 is designed to collect data and easy to integrate into existing systems through serial communication like RS-485 or analog outputs like 0-10 V / 4-20 mA. The L201 monitor comes with Rugged Connect software which is designed with the needs of Test platform or Industrial Process monitoring integration needs. It has the data integration capability of multiple test platforms. Rugged Connect software is designed to collect data from 6 systems simultaneously. Plug and Play functionality provides the flexibility to interchange sensors without the inconvenience/ concerns of calibration. Industry standard drivers availlable for a quick and easy connect to most popular laboratories softwares. There is a dedicated team for application specific customizations for fiber optic sensors,  monitor configuration and software integration to simplify the data collection of testing and monitoring applications.
