This constant (expressed power milliwatts required self-heat thermistor above ambient temperature) increases slightly with increasing temperature. lead length type lead, type encapsulating material (epoxy, Durez, stainless steel probe, thermoplastic probe, etc.) mounting thermistor/assembly, medium surrounding environment (flowing gas, still air, water, oil, etc.) other factors generally determine dissipation constant thermistor/NTC thermistor sensor assembly. Given variables that affect D.C., recommended that prototype should tested under actual operating conditions determine maximum allowable input current. current through thermistor must small enough produce negligible self-heating error thermistor maximum measuring controlling temperature. same time, current should large possible maximize system sensitivity. rate heat loss under actual operating conditions could fixed constant from system system, D.C. would only consideration determining maximum power dissipated offset allowance could made. example, D.C. thermistor assembly been determined mW/°C stirred bath (the medium measured) desired measure bath absolute temperature accuracy maximum power that should developed thermistor measuring current 0.15 This keep self-heat factor less measurement accuracy. formula this mW/°C 0.15 D.C. thermistor/NTC thermistor sensor assembly determined first measuring zero-power resistance thermistor temperature points apart. thermistor then placed series with variable voltage supply, current meter, sufficiently large enough resistor prevent much current flowing through circuit allowing thermistor "run-away". highresistance voltmeter connected across thermistor. power supply then gradually increased until voltage across thermistor current through indicate resistance equal measured resistance upper temperature.

Selection Resistance Value Typically, thermistors specified and/or referenced However, equally important consider minimum maximum resistance values extremes operating temperature range. minimum resistance maximum temperature point must meet input requirements measuring circuit. resistance low, errors contact resistance, line resistance self-heating increase. recommended have least 1000 high temperature range. Conversely, maximum resistance minimum temperature point must high measurement circuit input. Range switching with more probes should considered minimum/maximum resistance values cannot with thermistor. Sensitivity also important consideration selection correct resistance value. Usually, minimum maximum allowable resistance values typically limit this selection. then must determined which resistance values maximize output measuring system over entire range, taking into consideration maximum input current determined dissipation constant allowable self-heat error. Curve Selection present, curves available from Vishay Dale. Each material different characteristic. Given different resistivities different materials desirability maintaining uniformity size, resistance values (R25) available curves. Once minimum resistance maximum temperature determined, divide this resistance value given R-T/R25 ratio from curves determine approximate value. (NOTE: ratio tables increments included pages 16.) value available curve, select another until appropriate curve determined. Then, select standard value that closest approximate value. Calculate maximum resistance minimum temperature multiplying selected given R-T/R25 ratio. selected curve value meet predetermined minimum resistance, maximum resistance sensitivity measurement system, then tolerance next consideration.
Thermistors
Tolerance Most temperature measurement control applications express their limitations accuracy temperature units (i.e. °C). When designing system, important consider overall measurement accuracy components. thermistor, coupled with system, will insure measurement accuracy Thermistors specified with either temperature tolerance resistance tolerance either single temperature point over temperature range. required temperature measurement accuracy over temperature range, more practical specify temperature tolerance lieu resistance tolerance. This because resistance tolerance specification over range will necessarily guarantee that required system accuracy will unless nonlinear (negative temperature coefficient) taken into consideration. expressed resistance change degree Since resistance change approximately equivalent temperature change, useful specifying temperature tolerances.

Typical accuracies would less than 0.15 over range temperature points selected from tables calculate within range, accuracy better than 0.01 assuming measurement accuracy least four significant figures preferably five.

Thermistor Assemblies
FEATURES
Standard custom assemblies available variety configurations Assemblies conveniently attach integral part system monitor control temperature added labor required prior assembly intended application
Standard custom assemblies available variety configurations. choice assembly style dependent application. primary factors which determine optimum configuration thermistor assembly operating environment, mounting, time response minimum dissipation constant. factors which vary considerably with assembly design time constant dissipation constant. time constant will typically greater duration encapsulated thermistors. This course, additional mass surrounding thermistor element; therefore, extending thermal transfer time. Dissipation constant will also greater assemblies. additional housing mass serves well heat sink. Greater power therefore required induce self-heating. Both time constant dissipation constant will vary with selected thermistor housing. Heat transfer properties housing, thermistor location, mass wire type determine these constants. recommended evaluate consult factory applications where critical.
