Ex-proof Sample Gas Probe (PROBEX)

In any sample gas conditioning, the sample take-off point is a very challenging part between processes and the sample conditioning system. Hence the Axis PROBEX sample gas probe is specifically designed for this harsh and robust hazardous environment with competitive cost. The reliable and long-term operation of any process analyzer depends upon the efficiency of the sample conditioning system for which dust, solid particulate, and moisture-free sample gas is essential. PROBEX is equipped & designed with efficient variable filters by removing aerosols, dust content, and humidity by ensuring the security of the analyzer as well as further sample conditioning system. The main application of the sample gas probe is to extract the gas for analysis in the Continuous Monitoring and Emissions System. Axis PROBEX ensures easy mounting and installation, optimum operation, and trouble-free maintenance

Changing the external filter element needs no tools and no disassembly of the sample lines. The complete filter assembly is removed out at the probe head side. This makes it simpler to check the filter element & gasket condition.

The PROBEX heated probe power supply can be in any of 110 VAC and 230 VAC. No thermostat or temperature limiters are necessary. For electrical connection provides a separate Flameproof Junction box suitable for operation in Zone 1 & 2 hazardous area provided.
