固定法兰式隔爆热电偶、铂热电阻 Fixed-flange explosion-proof TC and platinum RTD

产品详情

在化学工业、石化业、天然气和冶金等生产现场常伴有各种易燃、易爆气体、蒸汽、使用普通的热电偶、热电阻容易引起环境气

体爆炸。因些，必须使用隔爆型热电偶、热电阻用温度传感器，隔爆型热电偶、热电阻产品适用在dllBT4和dllCT5温度级别区间内具

有爆炸性气体的场所内使用。符合IEC60079标准，GB3836标准。

At the production site of chemical industry, petrochemical industry, natural gas and metallurgy, there often with various

flammable & explosive gas and steam, using common TC and RTD is easy to cause explosion of environment gas, therefore,

EPTC and EPRTD must used as temperature sensor. EPTC and EPRTD are suitable for the places with explosive gas between

temperature grades dIIBT4 and dIIBT5.

防爆级组：d ⅡBT4、Ex d ⅡCT5、Ex ia ⅡCT5（本安）、DIP DT T11（粉尘）。

Explosion-proof type: d II BT4, Ex d IICT5, Ex ia II CT5 (intrinsic safety), DIP DT T11 (dust)

外壳防护等级：IP54、IP65(GB4208标准)。

Enclosure protection class: IP54, IP65 (GB4208 standard)

温度组别与最高表面温度和引燃温度的对应关系

Correspondence between temp. class, max. surface temp. and ignition temperature

注：应在环境温度为－20～＋40℃，空气相对湿度≤95％（在＋25℃时）范围内运行。高于此环境条件下运行，则会降低其温度组

别。

Note:When operating,the environment temperature shall be -20~+40℃,the relative humidity shall≤95％(at＋25℃).The

temperature class will be reduced if environmental condition beyond this range.

热电偶、热电阻类别、测量范围、等级与允差

Type, measuring range, class and tolerance of TC and RTD

注：

（1）式中“ltl”为感温元件的实测温度。

（2）“★”表示允许偏差两者中取其大者。

Note:

(1)“ltl”is the measured temperature of the temperature-sensing element.

(2)“★”means to choose the bigger one between the two tolerances.

注：

（1）公称压力：2.5MPa。

（2）K内芯采用铠装元件。

（3）型号后面加“A”为ANSI标准法兰。例：WRN-440A。选用JB/T标准法兰“★”常规供货为1Cr18Ni9Ti，如需其它材质另行注明。

Note:

(1)Nominal pressure is 2.5MPa.

(2)K inner core is sheathed element.

(3) For the model adding A, it is ANSI standard flange. For example: WRN-440A. “★”means normal supply is 1Cr18Ni9Ti, if other

material is needed, please indicate it separately.
