Platinum RTD Temperature Sensors with 3-Wire Leads

Innovative Sensor Technology's RTD sensors feature laser-welded insulated wires up to 1000 mm long. The 3-wire construction compensates the wire resistance and is ideal where tight tolerances are requested. Additional features are available upon request, including a metalized backside and a round ceramic housing for dry environments.
