500 Series
Packaged Temperature Probes
DESCRIPTION The 500 Series is available in a wide variety of housing styles
The 500 Series is broad portfolio of air/gas, liquid and surface and materials, R-T (Resistance-Temperature) curves,
temperature probes that use Honeywell's NTC (Negative mounting methods, mechanical interface, electrical interface
Temperature Coefficient) thermistors. and connector types to meet most applications.
Thermistors can be very effective in sensing temperatures of In addition to custom configurations, a variety of existing
gases, liquids or solids because of their enhanced sensitivity. designs is available.
These small, easy to install probe assemblies support and
position the thermistor elements within the media to be Honeywell also offers RTD (Resistance Temperature Detector)
monitored as well as protect the thermistors against damage in technology that may be packaged into probe assemblies for
use or handling. The assemblies also help direct thermal or similar applications that may require an RTD linear output
fluid flow evenly across the thermistors for accurate instead of an NTC thermistor output.
temperature sensing.
The enhanced reliability, precision and stability of the 500
Series products allow the customer greater flexibility in
temperature monitoring and control. The wide operating
temperature range is -60 C to 300 C [-76 F to 572 F]
provides application flexibility.
