The 'optris CS' is a rugged device, benefiting from coated silicon optics and so can be used in ambient temperatures of up to 75°C, without cooling. This highly accurate, but rugged device can measure temperatures from –20°C up to 350°C.

Further features are: a scalable analogue output of 0 – 10 V or 0 – 5 V, adjustable signal processing, short circuit and polarity reversal protection, USB programming interface with software and a wide power range of 5 – 7 or 12 - 28 V DC.

The 'optris CSmicro' is even more compact and measures just 14 mm in diameter by 28 mm in length, with an M12 thread. Again, the sensor is housed in stainless steel but the processing electronics are integrated in the sensor cable itself, which facilitates small sensor dimensions.

In addition to providing all the features of the 'optris CS', the 'optris CSmicro' goes further and provides a programmable simultaneous alarm output for fast analysis and switching operationsas well as programmable emmisivity. A very fast response time of 30ms (CS and CSmicro) demonstrates the level of technical innovation these sensors bring to the infra-red temperature sensor market. The sensor can also be used in ambient temperatures of up to 120°C without having to cool the sensing head.
