Overview +

With increasing demand for improved product quality and efficiency, energy saving, predictive maintenance and emission reduction, thermal imaging cameras and systems play an important role in modern and industrial processing.

The new LWIR-640 long-wavelength thermal imagers build on more than 20 years of thermal imaging experience, expanding the market-leading range of LAND temperature measurement solutions. They offer a full temperature measurement range of -20 to 1500 °C (-4 to 2732 °F) in four ranges with a choice of different optics and lenses.

An integrated webserver with multiple I/O options enables the camera to be used autonomously or easily integrated into new or existing process control systems. The webserver provides easy camera access, control and setup, using a standard browser.

The LWIR-640 measures and streams live true-temperature images at up to 60 frames per second, providing high-precision temperature measurements and thermal profiles to continuously control, document, and visualise industrial processes.

Frequently Asked Questions +

Question	Answer
What is the smallest object whose temperature the LWIR can measure accurately?	In general, an accurate temperature measurement requires an area of 3 x 3 pixels, a total of 9 pixels. The size of this object depends on the LWIR’s angle of view and the distance of the object. The minimum object size is approximately where θ is the LWIR’s horizontal field of view and L is the distance between LWIR and the object being measured. For example, if an LWIR with 25° x 19° lens is positioned 5000 mm from and object, the minimum measurable detail will be
Do I need to buy the IMAGEPro software package?	LWIR has a built-in web browser that allows the user to view thermal images and perform simple analyses, such as measuring the peak temperature in a region of interest and output the value on a 4-20 mA interface, or to produce an alarm if the temperature drops below a certain value. These functions are sufficient for many applications. Where greater flexibility and processing power are needed, IMAGEPro is a powerful, flexible PC-based image processing package which allows the user to perform and display detailed analyses of the data produced by LWIR.
Can I install LWIR outdoors?	LWIR is weatherproof to IP66 and NEMA 4 and is rated for operation between -20 and +60 °C so it can safely be installed outdoors. However its operation can be affected by dirt or water drops on the lens, so it is usually best to install it inside the light industrial housing which provides additional protection, including a purged window and a sunshield.
Can I install LWIR in hazardous areas?	LWIR is weatherproof to IP66 and NEMA 4 so it can safely be installed outdoors. However its operation flameproof housing is specifically designed to accommodate the LWIR imager. It has a gridless widow which gives a clear and unobstructed view, and has approvals for Zones 1 and 21 (flammable gases) as well as Zones 2 and 22 (flammable dusts).
What I/O is available?	The LWIR imager itself has a variety of inputs and outputs. High-speed Ethernet Webserver showing live data and basic image processing Modbus TCP/IP for measured and derived data Configurable analogue signals: 4-20 mA output Selectable: 4-20 mA output or relay Selectable: 4-20 mA input, digital input or relay A wide range of additional I/O modules can be connected to the IMAGEPro PC-based image processing software.
