SENSCIENT ELDS™ Open Path Gas Detector

Fast Response Time, Fast Recovery Time

This demo kit demonstrates its fast response time and fast recovery time. The demo kit consists of one ELDS XD CH4, one 500mm wide steel box to represent a small duct, one cylindrical plastic tube to contain released methane gas, one bottle of methane gas, a length of flexible tubing, a simple relay with set-point control and two strips of colored LEDs. Red illumination indicates gas detected while green illumination indicates no gas detected.

Case Study: Process engineers at a refinery in one of the Rocky Mountain states were concerned about detecting the potential accidental release of hydrogen fluoride (HF) gas at their plant as part of a recent series of upgrades to the facility. Read more »

See how MSA's Senscient ELDS XD provides the highest level of weather and false alarm immunity while eliminating any need for manual gas checks.

Product Highlights

  • Senscient open path gas detector ensures best in class false alarm rejection

  • Gases detected: hydrogen sulfide (H2S), sour gas (H2S/CH4), methane (CH4), ethylene (C2H4), ammonia (NH3), carbon dioxide (CO2), hydrogen chloride, (HCl), hydrogen fluoride (HF)

  • Gas-specific Harmonic Fingerprint detection eliminates false alarms and prevents plant shutdowns

  • SimuGas automated function checks are recorded daily and eliminate need for manual intervention

  • Tuneable lasers scan more narrow portion of spectrum where water interference from weather conditions are minimized

  • Bluetooth wireless technology and SITE software simplifies commissioning, diagnostics, and event log retrieval

  • Senscient ELDS lasers are hard on fog, rain, and snow but are easy on the eyes with a Class 1 eye-safe designation

  • Fastest responding device for safety critical ventilation zone and cross duct applications

  • No costly communication cable required between transmitter and receiver

  • Significantly improves the safety, efficiency, and operational costs of your gas detection program

IR5500 Open Path Infrared Gas Detector

Product Highlights

  • The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas

  • Sensitive to both small (ppm.meter) and large (LEL.meter) gas leaks using dual detection ranges

  • Ideal for use in harsh environments (-55°C)

  • Single detection beam improves accuracy and reduces drift

  • Continuous self-check for fail-to-safe operation

  • Multiple communication outputs (HART, Modbus, AMS support) provide complete status and control capability in the control room

  • Unitized display makes it easy to operate

  • Automatic gain control compensates for dirty optics, rain, and fog
