Based on the rugged humirel humidity sensor, GP3516 is a dedicated humidity plug and play transducer designed for OEM applications where a reliable and accurate measurement is required. Direct interface with a micro-controller is made possible with the module�??s humidity linear voltage output. The threaded end ensures proper mounting of the sensor inside te camber. GP3515 is specially suitable for humidity chambers applications. Main features Tests under harsh chemical conditions demonstrate good operation in presence of salt atmosphere, SO2 , H2S, O3, NOx , NO, CO, Softener, acids (H2SO4, HNO3, HCl), HMDS, Insecticide, Cigarette smoke . Threaded end for convenient and proper mounting. Reliability not affected by repeated condensations Full interchangeability. Better than +/-3%RH and +/-0.15°C Typical 1 to 3.6 Volt DC output for 0 to 100% RH at 5 V DC supply Humidity calibrated within +/- 3% RH @ 55% RH Ratiometric to voltage supply within the specified range Resistance to chemical and physical stresses GP3515 has circuit to protect against Electrostatic discharges upto 15 KV air discharge. GP3515 is protected against reverse polarity GP3515 is not light sensitive Additional tests under harsh chemical conditions demonstrate good operation in presence of salt atmosphere, SO 2, O 3, NO, CO,CO2, Softener, Soap, acids. Dimensions: Length: 90mm, Diameter: 19mm , Threading: M18 (Male -)
