Purpose of the development: Spectral ratio pyrometers DPR-1 designed for contactless measurement of the actual temperature of heated objects regardless of their emissivity

Recommended application field: Application pyrometers DPR -1: · In the metallurgical industry for measuring the temperature of molten metal in the ladle , chill molds , blast furnaces , open-hearth ; · Spill liquid metal into molds ; · Temperature control in rolling mills (hot and cold rolled) ; · Control and automation of the melting process in the manufacture of parts in the vacuum melting furnaces ; · On the refractory and coke plants for temperature measurement in gas furnaces ; · Forging shops in forging metals; · Shops factories in the manufacture of wires, fittings , rails, tubes of different diameters ; · Factories for non-ferrous metals smelting control , hire and chillingly details regardless of the type of metal; · Temperature control during welding joints ; · During quenching and roasting items in induction furnaces ; · In measuring the temperature between the coils of the inductor.

Technical characteristic: Specifications pyrometer following : - Measured temperature range , C * 200 to 3000 - Accuracy , * C ( throughout the range ) ± 5 - The level of sensitivity , C * 1 - Coefficient of sight (optional) from 30 to 100 - Overall dimensions (maximum ) 122 x 114 x 275 - Weight, kg ( not more than) 2.0 - Measuring time with 0.25 - Time of continuous operation : battery , 8 hours from an external source clock hours - The range of distances 0.4 m ... 50 - Powered by batteries or network 12V/130mA or 220V/50Hz - Mean time between failures ( reliability ) , 16000 hours - Average service life, years 10

Advantages over analogues: Currently, the company is the only one among domestic , which produces remote pyrometers spectral ratio ( two-tone ) DPR -1 to control the temperature of 200 * C to 3000 * C with an accuracy of ± 5 * C throughout the measuring range . Benefits pyrometers DPR -1: · Provide high accuracy temperature measurements over the entire range ; · Reliability and stability of the measurement results ; · Measurement results are independent from the environment (pollution by foreign gases , water vapor , dust, etc. ); · The possibility of accurate temperature measurement for mobile , vibrating objects; · The ability to accurately measure molten aluminum ; · Devices are not afraid of magnetic fields and work near induction furnaces ; · Measuring accuracy independent of the object's surface (the presence of partial dirt oxides , slag , etc. ); · Does not react to partial contamination of the lens unit.

The development stage readiness: Introduced in production

Technical and economic effect: Pyrometers DPR -1 certified and listed in the State Register of Ukraine at number U1308 -09 , DPR -1 pyrometers passed recertification and received a certificate of conformity and certificate number UA-MI/2r-3152-2010 UkrSEPRO № UA1.003.0173207- 11. Devices were tested for stability, reliability , ease of maintenance on many mills and factories and won tenders in comparison with foreign . They've been a long time (many more than ten years ) has been successfully applied in such enterprises as: MK PJSC "Azovstal " Company " Interpipe Niko Tube " , PJSC " Nasosenergomash" ( the amounts ), JSC "Motor Sich" , PJSC " Khartsyzsk Tube plant " , JSC" plant Druzhkovsky metal products " PrJSC " Krivoy Rog mining Equipment Plant " , JSC" Energomashspetsstal " ( Kramatorsk ), etc.

Description of the development:
()
Measurement technique based on the use of the ratio of energetic brightness in two spectral bands of temperature. The calculation of this relationship , taking into account the ambient temperature and the analysis results of the peak detector are entered into the program and input to the microprocessor , which enables high-precision measurement and correction . The sensing element is a radiation receiver plane- parallel plate made from a high of polarized pyroelectric material , the opposite sides of which the sputtered electrodes . By radiation plate is heated and its spontaneous polarization is reduced, which appears to change the charge on the capacitor , which is registered . Independence of the temperature sensitivity of PED enables operation of devices based on them is not temperature . The measurement results are output to a digital display and an analog interface in the form of a current of 4 to 20mA and digitally via RC 485 or RC 232 . The communication protocol is compatible with the pyrometer teams functional modules I-7000 firm ICP DAS. For constructive implementation pyrometer combined single block device can be portable or stationary use . The device has a hole with thread M10 for stationary mounting device . In devices located charger which enables devices to operate from battery 12V or 220V .
