• 2-wire technology (series 40) or 4-wire technology (series 44) • Several spectral ranges for many application areas • Integrated USB interface, stand-alone operation (series 40) • RS485 interface for integration in bus systems (series 44) • High accuracy and fast response times PYROSPOT Series 40 and 44 Digital Pyrometers for Industrial Applications The digital pyrometers of PYROSPOT series 40 and 44 are especially designed for industrial purpose. The devices are suitable for temperature measurement on many different metallic or non-metallic surfaces. The special spectral range of DT 40G and DT 44G makes the device suitable for measurement of glass surfaces. The DT 40F and DT 44F is suitable for measurement through flames and combustions gases by working in also special spectral range. The solid body in compact, stainless steel housing allows usage even under rough environmental conditions. With a fast response time these Pyrometers are also suitable for fast measuring processes. Several fixed, vario or fibre optics realizes small measuring spot sizes. The temperature linear standard output signal of 0/4 to 20 mA allows easy implementation in existing measuring and controlling systems. The devices of series 40 are equipped with integrated, galvanically isolated USB interface on rear side, which allows parameterizing and software evaluation even without connecting extra power supply. Series 44 is equipped with RS485 interface for bus system integration and modules for USB and RS232. Advantages of non-contact temperature measurement are: • Measurement on difficult to access, moving, aggressive or very hot parts • Very short measuring and response times • No influence of the temperature of the measured object, non-reactive measurement • No material abrasion, non-destructive measurement • Long-life cycle of measuring point, no wear on measurement device To choose the most suitable pyrometer for your application, several properties of the measured object needs to be considered. The object being measured could be in any distance from the pyrometer but it has to be at least as big as the spot size in this distance. The material of the measured object and the required temperature range determine the choice for the appropriate device and spectral range: Material Temperature range Spectral range Metals, ceramics, molten glass 600 °C to 3000 °C 0.8 µm to 1.1 µm Metals, ceramics, graphite 250 °C to 2500 °C 1.5 µm to 1.8 µm Measurement through flames and combustion gases 300 °C to 2500 °C 3.9 µm Glass surfaces 100 °C to 2500 °C 4.8 µm to 5.2 µm Nonmetals, coated metals –40 °C to 1000 °C 8 µm to 14 µm DIAS Infrared GmbH · Gostritzer Straße 65 · D-01217 Dresden · Germany phone: +49 351 8717228 · fax: +49 351 8717230 e-mail: [email protected] · internet: www.dias-infrared.com Technical details are subject to change without notice.
