JWKZ High-Precision AI Temperature Controller Technical Specifications
• Input specifications:
Thermocouples: S(-50～+1760℃), K(-270～+1370℃), E(-270～+1000℃), J(-210～+1200℃), T(-270～+400℃), R(-50～+1760℃), B(40～+1820℃), N(-270～+1300℃), WRe3-WRe25(0～+2310℃), WRe5-WRe26(0～+2310℃), F2(700～+2000℃), etc. (accuracy 0.05 class, resolution 0.01℃). Measuring the temperature difference between the hot and cold ends of the thermocouple is the basic function of this instrument. The cold end uses internal compensation or external compensation. External compensation can use Cu50 or PT100, automatically identified by the instrument.
RTDs: Pt100(-200～+850℃), Pt1000(10～+100℃), Cu50(-50～+150℃), rF(0～300K)
(Accuracy 0.02 class, resolution 0.01℃, PT100 and Pt1000 have resolution 0.001℃ in the range of -10~+100℃)
(PT100 and Pt1000 have the same marking, automatically identified by the instrument)
Linear voltage (mV): -10~120mV (accuracy 0.02 class, resolution 1μV).
Linear resistance (Ω): 0~500Ω, 900~1200Ω (accuracy 0.02 class, resolution 0.001Ω).
Linear voltage (V): I5:0～5V, I10:0～10V, I200:0～200V, I500:0～500V, etc. (accuracy 0.05 class).
Linear current (mA): I2:0～20mA, I4:4～20mA (accuracy 0.05 class).
Linear (voltage, current) input requires custom modules (I5, I10, I200, I500 and I2, I4 modules).
• Sampling period: 1 sample every 0.2 seconds.
