The 4539 ATC can be retrofitted onto an existing average temperature probe. It converts Cu90, Cu100, PtCu100 and Pt100 temperature element resistance values into digital numeric data on HART protocol signal output. It is compatible to both multi-resistance thermometers (MRT) and multi-spot thermometers (MST).
To meet the tough demands of custody transfer applications, the 4539 ATC sensor and convertor combination is intrinsically safe and provides a maximum of 16 class A Pt100 elements for average temperature measurement.
Combining only the 4539 ATC water bottom sensor with convertor allows independent measurement of water interface level.
Average Temperature & Water Bottom Sensor and Convertor
Both high accuracy temperature and continuous water interface measurement data are transmitted by the HART converter to host gauges, such as the 6000 Servo Tank Gauge or 4590 Tank Side Monitor.
