A990 Interchangeable NTC Thermistor Sub-Assembly
Thermometrics A990 Series of Interchangeable NTC Thermistor Sub-assemblies consist of matched pairs of small, glass encapsulated thermistor beads which are connected in either series or parallel circuit configurations. These sub-assemblies are available in a variety of styles which enable them to be used in measuring the temperature of liquids or solids or to be encapsulated into larger housings such as hypodermic needles or closed end sheaths. The sub-assemblies provide interchangeable resistance-temperataure characterisitics in extremely small, fast response packages, which are easy to handle.
