Optris CTi LThot Pyrometer for High Ambient Temperatures
(250°C Ambient Temperature without Cooling)
The Optris CTi LThot temperature sensor has been developed for the most extreme conditions in high-temperature areas and is acclaimed for its especially high temperature resistance. The infrared thermometer has an ambient temperature of up to 250 °C without additional cooling.
The IR pyrometer is especially suited for applications in driers, in tempering for metal and glass industries, in the processing of plastics and textiles, and in the semiconductor production.
The Optris CTi LThot sensor has a miniature sensing head at just 29.5mm diameter x 55mm long and allows the sensor to be installed in applications where space is at a premium.
The separate electronics enclosure box provides a full range of outputs and inputs as standard including 0/4-20mA, 0-5, and 0-10 V, and type K thermocouple. It’s also possible to incorporate an interface card which provides simple integration into your existing process control equipment. Options include USB, RS485, RS232, relay , Modbus RTU, Modbus TCP, Profinet, and EtherNet/IP interface and the license-free Compact Connect software.
