Engineering Note:
The repeatability of this circuit will be

Sensor Notes:
•
0-5V output sensors can be used with ClearLink, but there will be a
loss of 1 bit of resolution (provided they are compatible with the
ClearLink supply voltage (Vsupply).
•
0-20mA sensors can be used with ClearLink, but there will be some
loss of linearity near zero current (this is sensor dependent).
