September 20, 2011 - Non-contact MI3 temperature measurement systems from Raytek are now available with Modbus or PROFIBUS interfaces, in addition to the RS485 option. The infrared pyrometers from the MI3 series consist of an extremely fast miniature sensing head and a separate electronics box, either in a protective housing or in a DIN rail housing.
The three models cover a measurement range from -40 to +1,650 °C. The broad temperature range and high data quality mean they can be used in a wide variety of applications, in particular in process monitoring. The reading is converted into a digital signal directly in the sensing head. Combined with functions such as automatic identification of broken head wires, this significantly increases data reliability. At only 28 mm long and 14 mm wide, the IP65 sensing head in its stainless steel housing is one of the smallest stand-alone infrared pyrometers in the world.
In its OEM version it can be directly connected to existing monitoring systems via the internal digital bus: unlike its competitors, it does not require an additional electronics box. Another unique selling point of the MI3 series is its multiple sensing head design: up to eight individually addressable sensing heads can be connected to an MI3 electronics box – this minimises acquisition costs and installation effort. Parameterisation and operation are extremely user friendly. Furthermore, the digital communication between sensor and box, and a patented automatic head registration enable plug & play. The robust MI3 sensors have excellent EMC characteristics and can be used in ambient temperatures of up to 120 °C without cooling.
The DataTemp MultiDrop software included with the electronics box allows unlimited remote access to all process values and parameters. Using the standard USB interface, users can easily log in on site for diagnostic purposes, for instance.
