LFW11 — RTD and transmitter output difference
LFW11 is described as an indoor precision temperature product with platinum resistance sensor technology. A PT1000/RTD resistance output is different from a powered 4–20 mA or voltage transmitter, so confirm the specific circuit variant and host interface. Avoid mounting near radiators or direct sunlight; sensor surface response may differ from representative air. An accuracy quoted at 0°C/25°C is not automatically constant over the entire ambient range.
