Temperature Measurement Radial Leaded Glass Encapsulated Bead MF51 NTC Thermistor
I Description Of The MF51 NTC Thermistor
Ampfort MF51 series of Glass Encapsulated thermistors are a special breed of NTC thermistors. Hermetically sealed, these small thermistors eliminate resistance reading errors caused by moisture penetration and they function efficiently in extreme temperatures as well as under severe environmental conditions.
This class of thermistor is free from limitations due to solder temperature, which enables them to offer users a wide operating temperature range of “-55 °C to +200 °C”. With diameters of only 1.5 mm, the devices’ small size allows for encapsulation in a variety of housings, such as ring lugs and hex nuts.Radial leaded glass encapsulated thermistors provide a low cost option for applications that require superior stability and high temperature operation. The thermistors are glass encapsulated to allow for operation in a wide array of environments including high humidity and rapid thermal cycling. The small size allows the sensor to react quickly to small temperature changes.
