Upsi

UPSI manufactures and sells humidity and temperature sensors and measuring electronic systems, designed by the SPSI research and development laboratories, specialised for 30 years in physical quantities measurementThe company capacitive technologies researches and development have been successfully employed in specific civilians and militaries applications for fifteen years, where others market products accuracy and reliability could not meet the requirements. During the last years these reliability and low market prices have allowed this technology to be applied in large volume distribution.To avoid instability cause by the interfaces the capacitive humidity cell is directly build the active substrate upper side and a digital output conditioner is integrated in the backside.The UPSI humidity and temperature micro-systems based on the original SPSI UPSICAP MSS Bi-Face technology have an excellent stability and full interchangeability without recalibration
