Fully Integrated Infrared Pyrometers with LED Focussing and Wide Measurement Range

A new series of fully integrated infrared pyrometers providing high accuracy, flexibility and ease of use has been introduced by Ametek Land. The SPOT product line uses a patented, pulsed green LED to confirm spot size and focus, eliminating the safety concerns found with laser-based sighting.

There are eight models spanning temperatures from 250 to 1800oC/ 484 to 3272oF with wavelengths ranging from 1.0 to 1.6µm. The choice of measuring range and wavelength makes them suitable for numerous applications in iron and steel production, metal forging, heat treating and cement production among others.

SPOT pyrometers combine Ethernet, Modbus TCP, analogue inputs and outputs, and alarm contacts within a single device; no separate processor is required. Configuration settings and readings are available on a rear display, remotely via a web browser, or through proprietary SPOTViewer software. They are designed for simple installation and are interchangeable with older spot pyrometers.

Fibre optic versions allow the optic head to be mounted in a hostile environment, with the detector and electronics enclosure located several meters away. This permits viewing of targets that are inaccessible or in areas with high RFI (radio frequency interference) or ambient temperatures where water cooling is not possible.

SPOTViewer software allows users to configure, display and log data for up to 254 different pyrometer locations.  The software permits effective use of the pyrometers in smaller operations where traditional process control systems are absent.
