Explosion-proof type and grade group level groups: dⅡBT4 or dⅡCT4 dⅡBT6 or dⅡCT6 intrinsically safe level group: iaⅡBT4 or iaⅡCT4 (more on style) iaⅡBT6 or iaⅡCT6 (more on type) Housing protection class IP65 WZPK-131 Armored thermal resistance armor works thermal resistance is the use of material changes in temperature Assembly thermal resistance market price, its resistance changes with the characteristics to measure the temperature. When the resistance changes, the working resistance of the meter will show the corresponding temperature value. The main technical parameters Product performance standards IEC751, JB / T8623-1997, JB / T8622-19975, thermocouple wire thermocouple wire diameter material in the form of single double-supported tube diameter Φ3 Φ4 Φ5 Φ6 Φ8Φ4 Φ5 Φ6 Φ8 casing material 1Cr18Ni9Ti1Cr18Ni9Ti assembly Thermal Resistance Parameters | Assembly thermal resistance | Anhui Electric Group Co., Ltd. provided by the Anhui Electric Group.
