CTi Series

Small Sensor Head, Separate Electronics Box – Big in Perfromance

The optris CTi is a high-performance industrial pyrometer designed for precise non-contact temperature measurement in demanding manufacturing environments. This compact infrared temperature sensor combines proven pyrometer technology with modern connectivity features, making it ideal for industrial automation and process control applications.

Built on a reliable and trusted platform, the CTi pyrometer features an innovative modular two-piece design that allows any electronics box to pair seamlessly with any IR sensing head without compromising measurement accuracy. This modular pyrometer architecture enables rapid sensor head exchange and simplified maintenance procedures, while maintaining outstanding accuracy of ±1% or ±1°C on temperature measurements.

The ruggedized sensing head operates reliably in ambient temperatures up to 180°C without requiring additional cooling systems, making this industrial pyrometer suitable for harsh manufacturing environments. Despite its ultra-compact design—featuring one of the smallest infrared sensor heads in its class—the CTi delivers exceptional optical performance with up to 22:1 optical resolution for precise spot temperature measurement. Besides the integrated USB-C interface for fast commissioning, the pyrometer offers versatile analog outputs including selectable 0/4–20 mA, 0–5 V, 0–10 V, and thermocouple type K signals. Advanced digital communication options include EtherNet/IP, PROFINET, Ethernet TCP/Modbus TCP, EtherCAT, IO-Link, Modbus RTU, RS485, and RS232 interfaces, plus dual isolated relay outputs for seamless industrial network integration and temperature control applications.
