The Advantages of Single-Detector Dual-Wavelength Pyrometers

Dual-Wavelength Pyrometer
Dual-Wavelength Pyrometer
Single-detector, dual-wavelength sensors offer all of the capabilities of two-color sensors plus these added advantages:

Dual-Wavelength Sensors ...
  • Measure Low Temperatures – as low as 200˚F / 95˚C and above  Fiber-Optic 400˚F / 200˚C and above
  • Provide a Real-Time Measure of Temperature, Ambient Temperature, Emissivity and Signal Dilution
  • Can Measure Single-Wavelength and Dual-Wavelength Temperature Values Simultaneously
  • Include ESP Filtering to continuously measure intermittent targets or to eliminate intermittent interferences
  • Select models uniquely view clearly through Water, Steam, Flames and Combustion Gasses with thoughtful wavelength consideration
  • Select models uniquely view through Plasma and Laser Energy with thoughtful wavelength consideration
  • Are 20 times less sensitive to Scale and temperature gradients compared to two-color sensors
  • Are 20 to 100 times less sensitive to optical obstruction and misalignment compared to two-color sensors
The video below demonstrates a side-by-side comparison between an existing 2-color pyrometer and two Williamson Dual-Wavelength Pyrometers. Williamson Dual-Wavelength pyrometers are 20 times less sensitive to scale due to greater separation between wavelengths, when compared with 2-color pyrometers. Two-color sensors are an appropriate choice for many common temperature measurement applications. However, when certain conditions are present such as water, steam, scale, severe temperature gradients, severe or intermittent optical obstruction, flames, combustion gasses, laser energy, plasma, small targets and low temperatures, or when real-time emissivity measurements, measurement condition validation, or calibration stability are required, dual-wavelength pyrometers are a more appropriate choice.

Sensepoint XRL Gas Detector by Honeywell Analytics

Sensepoint XRL Gas DetectorThe Honeywell Analytics Sensepoint XRL is a single-sensor fixed gas detector is designed to meet the needs of industrial applications and supports the following interfaces, dependent on the model:

  • Analog output: Sensepoint XRL features current loop output, supporting signals in the range 0 to 22 mA. Typically this interface is referred to as 4 to 20 mA.
  • Digital output: Sensepoint XRL supports Modbus RTU digital communications.
  • Mobile app: A mobile app is available to commission and maintain the Sensepoint XRL gas detector.

Honeywell innovation enables customers to pair the gas detector with their mobile phone, and then use an app to perform many tasks related to installation, commissioning and maintenance. By using Honeywell's Bluetooth Low Energy (BLE) technology, you can install, commission and maintain your Sensepoint XRL gas detector from your mobile device. By using their gas detector app you can mange the device from up to 10 meters away.

Sensepoint XRL is available as a flammable gas detector for the detection of potentially explosive gases, or as a toxic gas detector for the detection of a range of toxic gas hazards commonly found in industrial facilities.
