1.LFW20-A4-50-1-0-G2-0-L100-1 represents an armored temperature transmiter;outout 4-20mA;accuracy 0.5%FS;temperatureange O-200℃(cold end required);junction box fom is waterproof;instalation method is G1/2 extemal thread(fxed thread installation);no protective sleeve;probe length 100mm;cold end length 100mm.
2.When selecting the instalation method and probe length,the selection should be consistent with sleeved type or drect insert type.
3.The operating temperature without cold end should be≤120℃;when the operating temperature is>120℃,you are advised toincrease the length of the cold end
4.Protection sleeve parameters:diameter 10mm,mounting thread G1/2 male,lengh matching the length of the probe.
