Senscient ELDS Open-Path Gas Detectors (OPGD) 2000 and 1000 Series detector, transmitter and receiver units
The Senscient ELDS Open-Path Gas Detectors (OPGD) 2000 and 1000 Series detector, transmitter and receiver units have received CSA and BASEEFA 10ATEX0066X hazardous area certifications, enabling their use in potentially explosive or hazardous environments in the U.S., Canada and Europe. They are designed for use in challenging environments, such as offshore platforms, petrochemical facilities and refineries, and other industries handling toxic or flammable gases. The systems detect hazardous gases over a specified line of sight, triggering multi-channel analog output signals to a remote control system.

SenseLine ELDS series open-path gas detectors
SenseLine ELDS (enhanced laser diode spectroscopy) series open-path gas detectors feature the manufacturer’s patented Simu-Gas technology, which eliminates in-field gas testing and allows users to perform remote, on-command, functional testing of the detectors from a programmable logic controller (PLC) at a control center or from a PDA. Simu-Gas controls both the synthesis of laser diode drive waveforms in a transmitter and the recognition of “harmonic fingerprints” by a receiver. Unique harmonic fingerprints are produced when a target gas in the monitored path absorbs the transmitter’s laser diode radiation. When the receiver recognizes the fingerprint, it calculates and then displays the quantity of the target gas. The accuracy of the gas detector is confirmed by comparing the gas reading on the receiver to the quantity of target gas simulated by the transmitter. Testing can be performed at any desired frequency with automatic data logging, and without having to physically access individual gas detectors or handle hazardous gas cylinders.

SenseLine detector
The SenseLine detector is based on open-path gas detection (OPGD) using enhanced laser-diode spectroscopy (ELDS) technology. This eliminates the risk of false alarms by providing significantly better sensitivity for flammable gases and low ppm-level toxic-gas detection. This detector can pick up signs of a gas leak early enough so that work can be done to eliminate the danger.
