aytek has launched an enhanced version of its ThermoView Pi20 process imager with DataTemp Pi (DTPi) software. Described as a rugged, yet easy-to-operate thermal
imaging solution, it includes two additional cameras, a new enclosure and C++ software development kit (SDK) allowing for use in a wide range of process environments. Designed for automated monitoring and
control of continuous or stationary targets, the ThermoView Pi20 fixed-mounted process imager provides an automated view of a process, allowing plant operators to shorten process start-up times and lower production line changeover costs. The camera is paired with intuitive DTPi software, which minimises or eliminates the long learning curve associated with many process imaging systems. The ThermoView Pi20 is now even more
robust and versatile with the addition of two 45-degree remote focus cameras and a new ‘outdoor’ enclosure. The company says that this solution is ideal for applications ranging from furnace refractory monitoring to semiconductor/ solar manufacturing and production of glass, plastics, automotive components, building materials, food and beverage products, and petrochemicals. Customised solutions are also available for engine testing, steel coating, metal forming, materials testing, solar module testing and automotive fabrication.
Together, the Raytek Pi20 camera and DTPi software offer multi-point control flexibility corresponding to areas of interest (AOIs) on the product with independent alarm settings. This provides the ability to reduce heating costs by applying heat to only the areas that need it. Users can also tell immediately when a product changeover is made if their process is under control. Process problems that show up as temperature anomalies are instantly detected, and image file and AOI archiving based on alarm conditions captures data showing when the alarm condition occurred. Featuring an IP54 rating, the rugged
ThermoView Pi20 camera is offered in two temperature ranges: -40 to 500°C and 200 to 2000°C. For each temperature range, three lens options are available: 21.7° x 16°, 30° x 22° and 45.2° x 33.7°. The ThermoView Pi20 provides easy networking over long distances using a standard Ethernet interface, which transmits up to 30 frames per second of imaging data from the camera. Additional fibre optic Ethernet accessories enable Ethernet cable runs beyond 90 metres, eliminating the need to place the PC operating DataTemp Pi software in a hazardous area. These features reduce the user’s capital investment costs by eliminating the need for specialized enclosures and expensive industrial computers to survive in a harsh field environment. Raytek has also enhanced its M13 Series
infrared temperature measurement system with MI3 1M and MI3 2M high temperature sensing heads. The new sensing heads extend the MI3’s performance for specific original equipment manufacturer (OEM) applications and high temperature manufacturing processes. Designed to deliver industry-leading
performance and flexibility at the lowest installed cost per measurement point, the Raytek MI3 Series represents a new generation of performance and innovation in non-contact temperature monitoring. These high-performance IR sensors reduce energy costs by allowing tighter process control and more efficient process heating. Improved control performance usually results in less product variation, higher product quality and increased throughput.
