On-line Thermal Imaging Camera Series Systems for Process Temperature Measurement and Control

The Surveyor cameras with new state of the art optical and electronic design uses USB 2.0 interface for real time thermography and infrared video recording with a 125 Hz frame rate. Ethernet ready connectivity is offered for long distance transmission and the use of I/O modules with multiple relays, voltage or current outputs for process control applications. User selectable shapes can be assigned to specific areas (ROI’s - Regions of Interest) that can be overlaid on top of the displayed thermal image which can be used to control temperature of multiple areas across the target. The Surveyor camera has a very small footprint, is water proof and can be equipped with exchangeable optics of 6°, 31°, 48° or 72° with adjustable focus capabilities.

Equipped with a wide temperature range from -20 to 900°C, this fully radiometric device, provides single shot or image sequences of thermal images for the temperature mapping or profiling of the target area to be observed. These images or series of images (e.g. movie files) can be stored in to a network file location for later retrieval and analysis and accessed by other computers on the network in real time.

The surveyor camera system fully integrates a measurement and control scheme for detecting hot or cold spots of bulk materials on conveyor belts, additional industrial process measurement applications include plastic, paper, rubber, textile, wood, coal, glass, Solar cell and semiconductor processes, metal treatment and ladle /furnace shell measurements, to insure operator safety and increase yield.

Network integration tools help to integrate the Surveyor into factory floor automation systems. The heavy duty stainless steel cooling jacket with air purge protects the camera in installation locations in harsh environments. The thermal imaging camera can be combined with pyrometers and blackbody sources for smart temperature observation systems (automatic online recalibration) to provide the highest calibrated accuracy on the market. Additionally the Surveyor can be operated in line scan mode with 200 linear points of measurement.

The Surveyor is ideal in automation and automotive R&D applications for the thermal stress analysis and is used to detect thermal anomalies of troublesome PCBs in test stations, finding hot spots on automotive brakes / clutches during testing and for reverse bias testing of solar cells for identifying broken interconnects. The high thermal sensitivity (NETD 0.04 K with 31° FOV and 110K pixels /points of measurement, enables the surveyor camera to present the finest temperature details of the target under observation.

An intuitive, simple to use, comprehensive windows based software package has a recording function for radiometric videos, snap shots, analysis and post processing of infrared images/ videos, as well as activation as a sophisticated high speed infrared line scan camera system.  Remote control of the infrared camera and complete set up of all its parameters are possible via a PC. Accessories for adaption to a wide range of industrial and scientific applications are available.

The operator can select movable spots with crosshairs and programmable measurement areas with automatic display of a maximum, minimum or average value within these Regions of Interest (ROI).  Temperature profiles along defined lines inside the image can be shown in separate graphs. The PSC-Camera connect software offers a selection of 11 different color palettes and a variety of ready to use measurement and display template layouts. The user can download improved updates of the software PSC-camera connect via the Process Sensors Website

A Process Interface (PIF out) with 0-10 VDC scaled linear output or can act as an alarmed and be switched to a 0 or 10VDC signal. There can be send out such as the temperature of the object or other measurement informations. A Process Interface input (PIF in) allows analog remote control of emissivity adjustments, triggered saved images and other functions. A DLL gives Engineers the opportunity to implement the thermal images into customer specific software programs as well as Labview.

The Surveyor camera is extremely lightweight and one of the smallest cameras in the world. With dimensions of 45 mm x 45 mm x 62 mm and a weight of 250g (incl. lens and 1 m USB cable) it fits in tight spaces and is ideal for use inside machines and test stations. The environmental rating is IP67 and is powered via the USB 2.0 interface with a current draw of maximum 500 mA.

Process Sensors Corporation continues to expand its product range of thermal imaging cameras and non-contact infrared thermometers.

Process Sensors Corporation is a private company with a manufacturing facility and corporate headquarters located in Milford MA, USA.  The company is a manufacturer and distributor of non-contact temperature and moisture measurement instruments as well as a wide selection of blackbody calibration sources.  Technical and application support is provided worldwide through direct, regional and sales representative offices.
