A choice of configuration is available : The most convenient and economical is a standard analyser with the cell mounted on the rear. Alternatively, there is remote sensor housing complete with flow meter and valve. Where cable lengths and/or hazardous area conditions are an issue, the transmitter can be located in the sensor housing.

Different sample conditioning systems are available, standard or bespoke, according to the process conditions. Filters, pumps and regulators can all be incorporated to deliver the sample in the correct condition. Bypass flow systems enable longer distances from process to analyser to be achieved. Vasthi engineers are ready to recommend the right system for you on receipt of the full gas stream specification.

For hazardous area applications the sensor may be mounted remotely in the hazardous area and safely connected.
