4-20mA Dew Point Transducer

PCD01 α-Al2O3/SiO2 hybrid dielectric dew point sensor is the world's most advanced humidity sensor using the latest nanotechnology, featuring long-term stability, fast response and durability in extremely high/low humidity levels. It can be recovered even after exposure to liquid water. It can monitor both dew point and temperature with a temperature sensor provided. Proper use of the meter can provide lifelong reliability without recalibration. The superior performance of the sensor makes it an ideal choice for many industrial applications.Patented drift-free α-Al2O3/SiO2 hybrid dielectric humidity sensorUltra-fast response time ensures safe and reliable monitoringVery low hysteresis makes it capable of giving reliable reading during rapid humidity change
Applications: OEM equipment manufacture, petrochemical, power, electronics, pharmaceutical, industrial gas, heat treatment, metallurgy, textile, aerospace, high speed rail, atomic energy, meteorology, natural gas, drying equipment, medical treatment, injection molding and warehousing, etc.
