DatasheetHTP501 Digital Humidity and Temperature Probe up to 120 °C (248 °F)

HTP501 Digital Humidity and Temperature Probe up to 120 °C (248 °F) The HTP501 is ideal for reliable and cost effective measurement of relative humidity (RH) and temperature (T) in demanding industrial process control applications up to 20 bar (290 psi). Besides the measurement of RH and T, the HTP501 calculates all humidity related physical quantities like dew point temperature (Td), absolute humidity (dv) or mixing ratio (r). Outstanding Measurement Performance The probe employs a high end E+E humidity sensing element which stands for high RH measurement accuracy over the entire T working range...

Features Protective Sensor Coating The E+E proprietary sensor coating is a protective layer applied to the sensing elements, their leads and soldering points. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive environment (salts, off-shore applications). Additionally, it improves the sensors’ long term stability in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface or on the electrical connections. Sensor Leads Protection In certain very aggressive applications, the combination...
