A two-colour pyrometer or ratio pyrometer is an advanced technology for non-contact temperature measurement. The two-colour models help with precise operations with superior accuracy and reliability, making these ratio pyrometers ideal for various industrial applications.

At its core, a two-colour pyrometer is a non-contact temperature measurement device that employs a more advanced technique compared to single-color pyrometers. Traditional models rely on measuring the intensity of the infrared radiation emitted by an object at a single wavelength. However, a material’s emissivity (its ability to emit infrared radiation) can significantly impact the accuracy of this measurement.

Two-colour pyrometers take a different approach. They simultaneously measure the infrared radiation emitted by the object at two distinct, closely spaced wavelengths. By analyzing the ratio of these intensities, the pyrometer can determine the object’s temperature with greater accuracy, even when emissivity fluctuates.

Manglam Electricals is a leading supplier of high-quality industrial instrumentation, including the Optris line of two-color pyrometers. Our range includes two exceptional models to cater to diverse industrial needs. Our robust two color pyrometer featrues fiber optic design for safe and reliable temperature measurement in the harsh enviroments. The other range of advanced pyrometers by Manglam Electricals incorporates video alignment and a two-step brightness reduction filter for exceptional performance in various industrial settings.

Why Partner with Manglam Electricals for Two Colour Pyrometers?

Applications of Two Color Pyrometers

Due to their exceptional accuracy, ability to handle challenging environments and user-friendly features, two-colour pyrometers find application in a wide range of industries:
Precise temperature control is crucial in various metalworking processes, such as forging, heat treating, and welding. Two-colour pyrometers ensure consistent and reliable temperature readings for optimal product quality.
Monitoring glass temperature throughout the manufacturing process is essential for controlling viscosity and preventing defects. Two-colour pyrometers effectively measure glass temperatures despite the material’s varying emissivity at different stages of production.

Food Processing

Maintaining proper temperatures during food processing is vital for safety and quality control. Two-colour pyrometers provide accurate temperature readings for various food products, even in environments with moisture or steam.
Consistent temperature control is necessary for optimal plastic molding and extrusion. Two-colour pyrometers offer reliable temperature measurements for different plastic types, regardless of emissivity variations.
