The BetaTHERM Glass Series NTC Thermistors are the perfect choice for applications that require high stability and performance in harsh environmental conditions. The Glass A Series uses a hermetic glass encapsulation to allow improved resistance to humid environments. With an operating temperature range of -55°C to +250°C, these NTC Glass Sensors are suitable for elevated temperatures or applications where rapid thermal cycling are present. With resistance tolerances of +/-1%, +/-2%, +/-3% or +/-5%, these NTC glass thermistors are suitable for the most demanding requirements.
