HTG3500 series modules are specified for maximum accuracy measurements within 10 to 95 %RH. Excursion out of this range (< 10% or > 95% RH, including condensation) does not affect the reliability of HTG3500 series characteristics. TEMPERATURE SENSOR 

Typical temperature output

Depending on the needed temperature measurement range and associated accuracy, we suggest two methods to access to the NTC resistance values.

RT  RN  e

RT RN T, TN β e

1 1    T TN 

  

NTC resistance in Ω at temperature T in K NTC resistance in Ω at rated temperature T in K Temperature in K Beta value, material specific constant of NTC Base of natural logarithm (e=2.71828)

 The exponential relation only roughly describes the actual characteristic of an NTC thermistor can, however, as the material parameter β in reality also depend on temperature. So this approach is suitable for describing a restricted range around the rated temperature or resistance with sufficient accuracy.  For practical applications, a more precise description of the real R/T curve may be required. Either more complicated approaches (e.g. the Steinhart-Hart equation) are used or the resistance/temperature relation as given in tabulation form. The below table has been experimentally determined with utmost accuracy for temperature increments of 1 degree. Actual values may also be influenced by inherent self-heating properties of NTCs. Please refer to MEAS-France Application Note HPC106 “Low power NTC measurement”.

Temperature Interface circuit Concerning the temperature sensor of the HTG3500 Series products, the following measuring method described below is based on a voltage bridge divider circuit. It uses only one resistor component (Rbatch) at 1% to design HTM2500 temperature sensor interfacing circuit. Rbatch is chosen to be equal to NTC @25°C to get: Vout = Vcc/2 @25°C. The proposal method connects Rbatch to Vcc (5Vdc) and NTC to Ground. It leads to a negative slope characteristic (Pull-Up Configuration). VCC (mV)
