SMALL BEAD & GLASS PROBE NTC THERMISTORS
Small Bead NTC Thermistors Series S14
Sensor Small Bead NTC Thermistors offer the advantages of
small size and mass, fast response time, extreme sensitivity to current and voltage
changes, and high stability. Typical applications include: biomedical assemblies. fluid
flow and fluid level measurement, thermal conductivity measurement, and gas analysis.

air): 0.10mW/Deg C.
- Custom Assemblies are available.
Glass Probe NTC Thermistors Series SP
Sensor Glass Probe NTC Thermistors are extremely useful in
applications where high stability and ruggedness is required. The availability of 4
standard outer diameters offers the designer the flexibility to fit the thermistor to the
design, rather than compromising the design to accomodate the thermistor. The .043"
diameter part offers the ruggedness of a glass probe thermistor and the small size
advantages of a bead thermistor, without the handling problems.
