E2T Pulsar4 Datasheet - 1

E2T PULSAR 4 AND PULSAR 4 ADVANCED Infrared thermometry for sulfur reactors and other high temperature furnaces between 350 and 2000°C (662 and 3632°F). The E2T Pulsar 4 Advanced measures two wavelengths for continuous and instantaneous measurement of refractory temperature (RT), gas temperature (GT) and integrated temperature (FF), reporting both readings simultaneously in one instrument. The Pulsar 4 is a single channel option for direct replacement of older Pulsar II products. AT A GLANCE Temperature Range 350 to 2000°C (662 to 3632°F) PRODUCT HIGHLIGHTS ■ Single-channel standard model programmable for gas or refractory measurement ■ Two-channel advanced model with simultaneous measurement of refractory and gas temperatures ■ Separate channel analog outputs and alarm relay set points ■ Instant or average readings ■ Smart FMA™ Flame Measurement Algorithm (Pulsar 4 Advanced only) ■ Explosion-proof certification II 2G Ex db IIB +H2 T4, IECEx, ATEX, FM (US and CDN) plus additional regional certifications ■ Integrated power supply, capable of operating with 24 VDC/120/230 VAC ■ RS485 Interface, HART protocol (Pulsar 4 Advanced Only) Measurement Uncertainty ±0.3% oR or 3°C +1 digit, whichever is greater Repeatability 0.1% of full scale span Analog Outputs Pulsar 4: 2 identical analog outputs 4 to 20 mA, linear Select one (RT, GT, or FF) Pulsar 4 Advanced: 2 analog outputs 4 to 20 mA, linear Outputs assigned to RT, GT, or FF TYPICAL APPLICATIONS ■ Sulfur recovery unit (SRU) monitoring ■ Thermal oxidizer monitoring ■ Petrochemical emissions monitoring Digital Interfaces RS485 addressable Pulsar 4 Advanced: HART Rev. 7 interface ©2019 Advanced Energy Industries,

Complex Processes Optimal operation of Sulfur Recovery Unit (SRU), Sulphur Burner, and Thermal Oxidizer furnaces require accurate process Gas (Flame) measurement and accurate Refractory measurement for operational safety (high temperature alarms). Of particular importance is control of the furnace process temperatures to prevent damage to the furnace refractory and assurance that reaction or destruction temperatures are reached and maintained. The Problem Thermocouple measurement of acid processes either fail prematurely or are protected by multiple thermo wells and sweep air systems that...

INSTALLATION PRINCIPLES Location on Furnace Utilization of the different temperature measurement systems depends upon the feed gases and burner design of the reactor. If you burn simple acid gas with combustion air, the Pulsar 4 should be installed two-thirds of the way downstream from the burner to the waste heat boiler. If there is a checker wall or choke ring, installation at Locations 2 and 3 (shown in the diagram below) is recommended. With oxygen-enrichment, refractory integrity is critically important. Burner design and location become paramount in determining the placement of the IR...

SMART FMA (PULSAR 4 ADVANCED ONLY) The E2T Pulsar Advanced uses a unique method called Smart Flame Measurement Algorithm (Smart FMA™) to compensate for varying gas transparency and their effects on gas and refractory IR temperature measurements. In a normal situation, a dirty flame can increase the signal emitted from the refractory depending on the quality, quantity and absorption of the flame. In a similar manner, some transparency of the flame or hot gas can cause refractory radiance to decrease the flame temperature. The FMA algorithm virtually removes these unwanted ‘crosstalk’...

FIELD CONFIGURABLE TO MULTIPLE TEMPERATURE COMBINATIONS Pulsar 4 The Pulsar 4 has the capability to measure one selected temperature measurement. For example, the single channel can measure refractory wall temperature or measure hot combustion gas temperature. The dual channel measurements capability is not activated for the Pulsar 4. An optional product firmware upgrade can be purchased to activate the Pulsar 4 Advanced capabilities. The Pulsar 4 is intended as a direct single channel replacement for clients with Pulsar II equipment. Each Pulsar 4 provides two identical analog outputs, but...
