Selection Notes

1. LFW20-A4-50-1-0-G2-0-L100-1 represents an armored temperature transmitter: output 4-20mA, accuracy 0.5%FS, temperature range 0~200°C (cold end required), junction box form is waterproof, installation method is G1/2 external thread (fixed thread installation)

, no protective sleeve, probe length 100mm, cold end length 100mm.

2. When selecting the installation method and probe length, the selection should be consistent with sleeved type or direct insert type.

3. The operating temperature without cold end should be ≤120°C; when the operating temperature is >120°C, you are advised to

increase the length of the cold end.

4. Protection sleeve parameters: diameter 10mm, mounting thread G1/2 male, length matching the length of the probe.
