PERFORMANCE Input types : thermocoules J,K,R,S,T,E RTD type Pt100, Ni100 Potentiometer min. 65 max 1000 Ohm Input Reference Current: 1.5 mA Max. Outputs: 4~20mA( 2-Wire ) 1~5V( 3-Wire ) Output Limits : 3.4 ~ 30mA typical Power supply : 12.6V ~ 36V DC ( Loop-powered) Accuracy :± 0.2% of full scale Isolation: none Operating temperature : -25 ~ +85℃ Operating temperature affect Less then ± 0.1% of output span per ℃ Wide Range Adjustment Zero : 20% of span Span : 20% of span Load Resistance 4 to 20mA : Road(max) = 600ohm 1 to 5 V : Road(min) = 150kohm Case Mat'l : ABS Display : L.C.D ¦ FUNCTION The TT-3000 converters RTD and T/C sensor input to proportional process current output signals. The output and power supply the same pair of wires. These loop-powered transmitters deliver high performance at a low cost. Rugged construction makes them suitable for mounting in the field. ¦ FEATURES AND BENEFITS Excellent accuracy and stability : ensure reliable measurements in harsh industrial environments Wide range and span adjustment: enable precise calibration. RTD and T/C signal linearization Improves accuracy and reduces drift Sensor compensation The sensor generates a signal corresponding to the actual temperature and is complete with a PTC thermistor which also electronic system (coldjunction).
