Method and system for monitoring condition of a sample handling system of a gas analyser

A condition monitoring system for monitoring condition of a sample handling system (110) connected to the gas analyzer (120) wherein the sample handling system (110) comprises a sample line for supplying a gas sample to the gas analyzer (120), and at least one sample handling device on the sample line for operating on the gas sample, the at least one sample handling device includes one or more temperature regulators for regulating the temperature of the gas sample, a pump for pumping the gas sample to the gas analyzer, a purge device for purging the sample line for clearing blockages in the supply line and one or more valves to regulate the flow of the gas sample in the sample line, the condition monitoring system comprising:

• a. a network interface for receiving one or more sets of measurements from a plurality of temperature and pressure sensors connected at plurality of positions in the sample line;
• b. one or more processors for:
• i. obtaining operating characteristics of the at least one sample handling device based on the one or more sets of measurements and a model of the sample handling system;
• ii. determining the condition of the sample handling system based on comparison of the operating characteristics of the at least one sample handling device against a plurality of reference values associated with the at least one sample handling device;
• and
• iii. generating an alarm based on the determined condition of the sample handling system, wherein the alarm includes at least one event relating to faults, warnings about failure, estimation of life of at least one sample handling device, estimation of condition of the at least one sample handling device, and schedule of maintenance for at least one sample handling device.
