Product Features

The Rugged Monitoring O201 is designed for reliability to operate in extreme EMI, RFI, Microwave, and high-voltage environments.

O201 Fiber optic monitor combines reliability and user-friendly configuration software. 

O201 is a multi-channel fiber optic temperature monitor with precision measurement for Original Equipment manufacturers.

O201 has a measuring range from -271 °C to +300 °C. The system offers 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.

O201 is designed to collect data and is easy to integrate into existing systems through serial communication like RS-485or analog outputs like 0-10 V / 4-20 mA.

O201 supports Modbus, CANbus protocols, and a system fault relay.

The module is designed with the capability to add additional application logic for customer-specific applications.

O201 has the data integration capability of multiple test platforms. Industry-standard drivers are available for a quick and easy connection to the most popular laboratory software.

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.
