CT - One of the world's smallest non-contact temperature sensors !

For plant engineers, maintenance technicians, field and service engineers, the CT temperature sensor is ideal for use in automation, mechanical systems, control engineering, plant construction environments and can measure temperatures from -40°C up to 900°C, with a temperature resolution of 0.1°C within 160 milliseconds. The unit has an optical resolution of 2:1, 15:1 and 20:1 (as standard). The standard unit is able to withstand ambient temperatures of up to 180°C without cooling.

The latest developments allow a very small spot size by using a miniaturised sensing head, measuring just 28mm in length and an M12 diameter connecting thread. The optical nature of the measurement principle enables the engineer to aim and focus the sensor head at the target to give a specific 'spot size'. With the help of a micro-lens, which can be installed in front of the integrated lens, the user is able to measure objects that have a diameter of just 0.6mm.

The products can be protected by mounting them in air purge collars. A new, innovative 'right angle' air purge collar allows a laminar flow of air across the front face of the sensor to maintain the sensor at constant temperature, but does not cool the target - a common problem with conventional cooling systems.

The sensor electronics are located separately in a die cast enclosure rated to IP67. The set up of the electronics is via a membrane pad fitted to the controller as standard, and can also be carried out via USB, RS232 or RS485 interfaces. In one customer application, an RS485 protocol, customised for time-critical applications, enabled measurements of up to 64 bus-connected sensors within 50 milliseconds.
