Infrared Thermometer (Pyrometer) from Optris CTi series
- Robust and compact, for non-contact temperature measurement of various surfaces from different distances in harsh industrial environments
- Industry-leading standard pyrometer with a modular two-piece architecture, consisting of an interchangeable measuring head and an electronic module in a separate IP65-protected metal housing with LCD display and configuration buttons
- Wide selection of available spectral ranges and measurement angles for optimal response in any application
- Competitive price without compromise, with excellent measurement accuracy – e.g. the LT version offers ±1% of reading or ±1°C and repeatability of ±0.1% of reading or ±0.2°C
- Exceptional resistance to high ambient temperatures – up to 180°C (CTi LT) or even up to 250°C (CTi LThot)
- Supplied as standard with a 1 m cable between the sensor and the electronic module, rated up to 105°C; longer or higher-temperature cables are also available depending on the application
- Power supply: 8–30 VDC, max. power consumption 1.2 W
- Various options for analog and alarm outputs: 0/4–20 mA, 0–5/10 V, thermocouple K, open collector NPN 24 V / 50 mA, relay outputs 60 VDC / 42 VAC, 0.4 A, etc.
- Various communication protocol options: EtherNet/IP, PROFINET, IO-Link, EtherCAT, Modbus TCP, Modbus RTU via RS485, RS232
- USB port for connection to a PC or smart device and for power supply
- Free software for Windows CompactPlus Connect and a mobile application for Android IRmobile, enabling extensive configuration, visualization, data logging, alarm limit setting, analysis, report generation, and more
- Explosion-proof version also available (CTi LTex)
- Configurable emissivity (Ɛ) of the measured surface from 0.05 to 1.100
- Configurable transmissivity (τ) of the measured surface from 0.05 to 1.100
- Cylindrical stainless-steel housing with frontal male thread M12×1 (M18×1 for LThot)
