Intrinsically safe average temperature device that can be powered and configured via the 6000 Servo Tank Gauge (STG) or 4590 Tank Side Monitor (TSM) via 2-wire HART connection Precision multi-spot Pt100 (Max.6) elements have fixed interval (2 m or 3 m). Both explosion proof (Exd) and intrinsically safe versions are available for installation in various classes of explosion hazardous areas Continuous measurement of average liquid and/or average vapor temperature Temperature profile throughout the tank is available by reading the position and temperature of each element Field communication to control room via 6000 STG or 4590 TSM via industry standards tank gauging protocols
