Thermometrics Glass Coated Bead NTC Thermistors Type B Series

Thermometrics Type B Glass-Coated Bead Thermistors consists of glass-coated bead thermistors on fine diameter platinum alloy lead wires. The special thin glass coatings provide hermetic seal making these thermistors unaffected by severe environmental exposures. They are suitable for most low cost temperature measurement, control and compensation, such as self-heated applications, including liquid level sensing and gas flow measurement.
