Like some Usain Bolt of the temperature measurement world, speed requirements and expectations for pyrometers are unrelentingly demanding. Typical examples are plastics processing machinery, such as those used for blow-molding PET bottles, which work on very short cycle times.
To assist with this and meet those demands, Optris now offer their new high-speed pyrometer, the CT 4M, designed specifically for such challenging tasks. With a detection time of just 90 µs, it is the fastest pyrometer within the product range at Optris.
The CT 4M measures within the spectral range of 2.2 µm to 6.0 µm, making it ideal for low-temperature measurements on metals, metal oxides, ceramics or for materials with an unknown or changing emissivity. In this case, low temperature means the range spanning 0°C to 500°C.
The sensor head of the new pyrometer is very compact; with a diameter of 14mm and a length of 28mm, it can easily be installed even where space is at a premium, for example directly within a machine. The remote electronics unit is connected to the sensor head via a cable which can be up to 15m long. Important parameters can be entered directly via three keys and an illuminated display. The integrated interface allows the CT 4M to be connected directly to a PC, where all settings can be fine-tuned in the CompactPlus Connect software. Date capture and recording are also possible using the software. Other serial interfaces or an Ethernet interface are also available as options.
Instead of a PC, the pyrometer can also be connected to an Android mobile device which has the free IRmobile app installed. This allows the settings of the pyrometer to be adjusted very conveniently during commissioning or maintenance work directly on-site. To connect the CT 4M to the process, two scalable analogue outputs and three I/O pins (programmable inputs/outputs) are available.
