#143465 - Linearisation Responding to: ???'s previous message |
With the topology we use, the bridge linearises the o/p slightly, and the midpoint is a fairly good point to start with. We use the circuit in the range -40<T<20 degrees C with a final accuracy measured at < 0.075 C, anywhere in the range.
