Accuracy, measurement range, electrical outputs, probe length and installation environment depend on variant and current revision. Check manufacturer data prior to equipment specification.
Official LFW22 sensor data — verified 23 October 2026
Current maker product page explicitly lists PT100 or PT1000 element variants for −50 to +450°C, or NTC10K / NTC20K variants for −50 to +200°C. These are passive temperature sensing elements, not evidence that every LFW22 ships with a 4–20 mA transmitter. Listed measurement accuracy at the respective reference temperature is ±0.2°C for platinum elements at 0°C and ±0.3°C for NTC at 25°C. Compatible media: gas and liquid subject to wetted materials; aluminum housing, 304 stainless steel probe and casing. Housing environment −40…+85°C; IP65 only after correct electrical termination.

LFW22 temperature sensing
Confirm whether the specified LFW22 is a bare temperature probe or a conditioned-output instrument before assigning controller terminals. Probe sheath, sensing element, connection cable and accuracy class must be obtained from the exact LEFOO datasheet. For duct, pipe or machine monitoring, check insertion depth, thermal coupling, response time and the maximum process temperature independently of ambient electronics limits.
