F139x FIXINST-A Al2O3 Dewpoint & Pressure Multi parameter transmitter

Measurement Range：-110 … +20 °Ctd

Characteristics

The F139x series integrates 3 sensors: temperature, humidity and pressure in a very compact space. It measures the dewpoint and simultaneously monitors the online pressure and outputs both the pressure dewpoint and the atmospheric dewpoint at the same time. When the dewpoint of the measuring medium is below -40 °Ctd, the aluminum oxide sensor is the most accurate, responsive andlong-term stability in comparison with other types of sensors. Meanwhile, it has excellent anti-pollution ability. Revolutionary auto-calibration circuit design automatically compensates for circuit drift caused by temperature, contamination, and aging, providing long-term stability and high accuracy measurementsInnovative temperature compensation algorithm and multi-point temperature compensation calibration, greatly improving the sensor’s temperature drift and ensuring high-precision dewpoint measurement over a wide temperature range.
