Features
¥ Rapid Time Response (1.3 second typical in liquids).
¥ DC (Dissipation Constant) = 2.0mW/oC typical in
still air at 25oC.
¥ Min./Max. Temperature Exposure = -80oC to 150oC.
¥ Available in custom probe assemblies.
¥ Proven Stability and Reliability
¥ Larger lead wires ease assembly requirements.
BetaCURVE Thermistor Series III are similar in
construction to Series I except for the use of larger (30
AWG) copper leads. This allows the Dissipation Constant
(D.C.) to be raised from o.75mW/oC to 2.0mW/oC. Larger
leads also facilitate easier handling during assembly
operations. The Thermal Time Constant is raised to 14
seconds in air. Custom resistance values and tolerances are
available upon request.
