THERMISTORS: TYPE A990
Type A990 Interchangeable sub-assemblies consist matched pairs small, glass encapsulated thermistor beads which connected either series parallel circuit configurations. These sub-assemblies available variety styles which will permit them used measuring temperature liquids solids encapsulated into larger housings such hypodermic needles closed sheaths. sub-assemblies provide interchangeable resistance temperature characteristics extremely small, fast response packages which easy handle. units shown available from stock with fast delivery. Resistance, tolerances temperature ranges other than those which indicated available upon special order. Other
sembly configurations available upon special order. Please consult factory special requests modifications. Maximum Operating Storage Temperature Optimum Stability 105°C.
