Description SELECTION CRITERIA INSTALLATION AND USE FIELD INSTALLATION

Industrial thermal resistance is used as a sensor to measure temperature. It is usually used together with display instruments, recording instruments and electronic regulators. It can directly measure the temperature of liquid, vapor and gaseous medium and solid surface in the range of -200 ℃ to 800 ℃ in various production processes.
According to national regulations, our company produces Pt100 platinum thermal resistors that comply with EC international standard graduation numbers and Cu50 copper thermal resistors that meet professional standard graduation numbers.
Product implementation standard: C751、IEC1515
                                                      JB / T8622-1997, JB / T8623-1997

 
Thermal resistance category Temperature measurement range ℃ Index number Allowable deviation △ t ℃
WZP platinum resistance -200~420 Pt100 Grade B (-200-800) ℃ Tolerance (0.30 + 0.005 | t |)
Class A (-200-650) ℃ Tolerance ± (0.15 + 0.002 | t |)
WZC type copper resistance -50~100 Cu50 (-50 ~ 100) ℃ Tolerance ± (0.30 + 6.0 × 10-3t)
Note: “t” in the formula is the absolute value of the measured temperature of the temperature sensing element.
Resistance value of thermal resistance temperature sensing element at 100 ℃ (R100) and its resistance Ro ratio at 0 ℃: (R100 / Ro)
Indexing number Pt100: Class A Ro = 100 ± 0.06Ω
                                       Class B Ro = 100 ± 0.12Ω
                                       R100 / Ro = 1.3851 ± 0.0012
Indexing number Cu50: Ro = 50 ± 0.05Ω
                                      R100 / Ro = 1.428 ± 0.002
