GasFinder MC

GasFinderMC is a 19” rack mount laser based gas detector that incorporates multi-switched fibre-optic ports to connect up to 8 different measurement heads. These heads can enable stack monitoring, short and long open path monitoring or local point measurements.

Reliable self-calibrating instrument Robust industrial design Gas specific - no interferences Fast response times - typically from 2 seconds Flexible configurations Reliable, proven technology Self calibrating - no calibration needed Easy setup menu No consumables and no maintenance Built-in data-logger and self diagnostics

GasFinderMC Multi Channel Monitor - Applications

The GasFinder MC has many industrial applications as a complete site monitoring solution. The Central Control Unit has 8 fibre optic outputs which interface with remote transmitter heads. There are three configurations of transmitter heads, each suited towards a specific application.

Open Path Remote Head

Suitable for ambient long path monitoring, roofline monitoring, and leak or emergency release monitoring. Mounted on an x-y adjustable platform, the open path remote head can be manually adjusted to cover several paths with one head, and combinations of open path remote heads can be used for redundant perimeter monitoring of high risk process units. Using multiple paths encircling a facility, cost effective leak detection can be achieved.

Cross Duct Probe With one second data rates, the cross duct probe is ideal for duct based process control or large diameter stack monitoring. Two cross duct probes can easily obtain data from the input and the output of a process container to measure the efficiency of the unit. The cross duct probe is designed to fit into a standard ASA 200 pipe flange.

In-Situ probe The in-situ probe is available up to 1 meter in length and is ideal for stack monitoring applications. The 10 micron filter allows gas to flow through for measurement while keeping dust and particulates out of the monitoring path. Fast data acquisition allows for efficient process monitoring and real time feedback, as well as safety and compliance data.

Extractive Multipass Cell The extractive multipass cell allows a gas sample to be removed from the process and analyzed offline. This sampling method avoids potential interferences from particulates and water vapour, and allows the sample to be monitored at a controlled temperature that may differ from the process temperature. The multipass cell provides 10m of optical path length.

Multipath Perimeter Monitoring:

Patented features provide laser gas detector leadership in price, performance, and ease of use.

·          “No phase adjustment” detection technology:

Enables paths from 1m to 500m without requiring any phase adjustments or calibration.

·          Built-in, permanent calibration reference cell:

Means GasFinders are delivered calibrated, stay in calibration and never need to be re-calibrated.

Measurement Principle: 

GasFinderFC houses a laser diode, drive electronics, and micro-computer subsystems. Fibre-optic cable carries the laser light to a separate probe (transmitter/receiver head), which directs the beam along a measurement path to a reflector. The return light is collected on a photo-detector housed in the probe (transceiver head) and the photo current is carried to the GasFinderFC via coaxial cable for analysis.

A portion of the laser beam is passed through a stable built-in reference cell to provide a continuous calibration update. The measure and reference signals are then compared to determine the actual concentration of gas along the measure path. This value is displayed on the back panel of the instrument. Serial and analogue signals are also available. The serial signal contains self diagnostic data. The GasFinderFC also has a built in data logger than can store up to 10,000 readings.

Continuous scanning of the fingerprint spectra (waveform) guarantees quality of the measurement and prevents unknown interference.
