0

Advanced Energy's E2T Pulsar 4 instruments provide infrared thermometry for sulfur reactors and other high-temperature furnaces in temperatures between 350 to 2000°C. Single channel standard model programmable for gas or refractory measurement. Two channel advanced model with simultaneous measurement of refractory and gas temperatures. Explosion-Proof Certification II 2G Ex db IIB +H2 T4, IECEx, ATEX, FM (US and CDN) plus additional regional certifications. Smart FMA™ Flame Measurement Algorithm (Pulsar 4 Advanced Only). RS485 Interface, HART protocol (Pulsar 4 Advanced Only).

The E2T Pulsar 4 is a single channel model for gas or refractory measurement and the E2T Pulsar 4 Advanced is designed to measure two wavelengths for continuous and instantaneous measurement of Refractory temperature  and gas temperature simultaneously.

The innovative Advanced Energy Smart FMA Flame Measurement Algorithm allows for accurate real-time flame transparency compensation and correction. Applying the flame transparency calculation with FMA removes the flame transparency errors due to the gas (flame) temperature.

  • Prevent damage to the furnace refractory with high temperature alarms
  • Install a single system with two independent infrared filtered detectors for gas (flame) and refractory measurements
  • Quickly react to control the furnace process temperatures with instant readings
  • Gain higher operational safety with accurate refractory measurement and high temperature alarms
  • Use Smart FMA to remove flame transparency errors that typical pyrometers experience (Advanced version only
