What minimum insertion lengths are recommended, as a rough guide, for multipart thermowells (from tubing) in order to minimise the heat dissipation error?

for gaseous media: 15 ... 20 x thermowell tip diameter
for liquid media: 5 ... 10 x thermowell tip diameter
for solid media: 3 ... 5 x thermowell tip diameter
(these standard values are only valid for static mediaThe gap between the thermowell and me ... More

What are 2-, 3- and 4-wire circuits?

This describes the number of wires connected to a Resistance Temperature Detector (RTD) (e.g. a Pt100). With a simple 2-wire connection, the lead resistance can influence the measurement value, the lead resistance  can be compensated with a 3- or 4-wire l ... More
