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. FEATURES POTENTIAL APPLICATIONS Air/gas, surface, immersion and liquid level Industrial: HVAC, refrigeration, office automation, air NTC type output compressors, industrial ovens and ranges, hydraulic Enhanced sensitivity systems, processing and packaging, power generation Small package size Transportation: heavy duty or sport vehicle engine oil, air Easy to install inlet, fuel, coolant or surface temperature sensing Enhanced reliability Aviation: engine bleed air or environmental control systems Enhanced accuracy Weather stations Enhanced stability/low drift Wide operating temperature range Wide variety of probe assembly styles Custom configurations available RTD linear output available 500 Series Table 1.
