The Gammapilot FTG20 is the world’s most advanced Geiger-Mueller counter with highest available sensitivity and outstanding features. Even under extreme process conditions like high pressure, high temperature, corrosiveness, toxicity and abrasion, the radiometric measuring principle can be employed without any problems.
For liquids, solids, suspensions and sludges etc. Particularly for applications under extreme measuring conditions, e.g. high pressure, high temperature, corrosiveness, toxicity, abrasion. All kinds of process vessels, e.g. reactors, autoclaves, separators, acid tanks, mixers, cyclones, cupola furnaces.
Temperature: No limitation (non-invasive, extraneous)
Pressure: No limitation (non-invasive, extraneous)
Switch time: Up to 0.4 seconds
International explosion protection certificates
Benefits
Sensor and transmitter: One instrument for all measuring tasks - can be used universally due to numerous certificates and approvals
Highest availability, reliability and safety, even for extreme process and ambient conditions
No recalibration after electronics exchange because of HistoROM data management concept and automatic decay compensation
Optimum adjustment to the respective application via a variety of sensitivity versions
Relay, 8/16mA (passive - two-wire loop powered) or 4 to 20mA output for easy system integration
Aluminum or stainless steel housing for heavy-duty applications
Easy commissioning and fast, on-site operation
