YSI 44000 Series Epoxy Encapsulated Thermistors
Thermistors provide highly accurate and stable temperature sensing for applications of temperature measurement, control, indication and compensation. Typical uses include precise measurements without the necessity of individual circuit calibration and with the advantage of precise interchangeability of sensors. Two interchangeability tolerances, ±0.1°C and ±0.2°C, and two thermistor configurations are offered. Teflon®-encased thermistors allow exposure to hostile environments such as conductive or corrosive liquids and particulate suspensions.

YSI 44000 Series Epoxy Encapsulated Thermistors
Precision Interchangeable Thermistors
Thermistors provide highly accurate and stable temperature sensing for applications of temperature measurement, control, indication and compensation. Typical uses include precise measurements without the necessity of individual circuit calibration and with the advantage of precision interchangeability of sensors. Precise cold junction compensation of thermocouples may be designed directly without “bread boarding” after mathematically deriving the circuit because of the superior interchangeability of YSI precision thermistors. Two interchangeability tolerances, ±0.1°C and ±0.2°C, and two thermistor configurations are offered. Teflon®-encased thermistors allow exposure to hostile environments such as conductive or corrosive liquids and particulate suspensions. A stiff wire placed in the tube also allows the thermistor leads to be formed to various shapes with slight finger pressure.
Time Constant
The time required for a thermistor to indicate 63% of a newly-impressed temperature is the time constant. For a thermistor suspended by its leads in a well-stirred oil bath, it is 1 sec. max. for standard thermistors and 2.5 sec. max. for Teflon®-encased thermistors. In still air, it is 10 sec. max. for standard thermistors and 25 sec. max. for Teflon®-encased thermistors.
Dissipation Constant
The power in mW required to raise a thermistor 1°C above surrounding temperature is the dissipation constant. For all thermistors suspended by their leads in a well-stirred oil bath, it is 8mW/°C min. or 1mW/°C in still air.
Stability
YSI thermistors are chemically stable and not significantly affected by aging or exposure to strong nuclear radiation.
