HT402-B Duct Humidity and Temperature Sensors Heavy Duty Transmitters for Industrial Applications up to 200°C

HENGKO® humidity temperature sensors in this series are supplied with a robust aluminium die cast housing with a stainless steel sensor temperture and humidity probe part to measure relative humidity or relative humidity and temperature in air and other non-aggressive gases for a working temperature range of up to 200°C. It can be used at pressures up to 8 bar, at temperatures up to 125°C or up to 160°C. These sensors are ideally suited for industrial applications, e.g. in drying processes. The advantages of the series are its improved dynamics, in particular at low air speeds and also its increased service life, even under more challenging operating conditions (pollutant impact or permanent humidity > 90 %rh). When air speeds are extremely high combined with a high number of particles, using the series is not recommended.

HT402-B humidity sensor also has an anti-condensation function. What is anti-condensation? Anti-condensation protection is a passive corrosion protection method for metallic surfaces that are prone to the formation of water droplets. The metallic surface is covered with a protective coating that isolates the surface from aggressive corrosion media such as moisture, salts, acids, etc. The anti-condensation preventive coating absorbs all the condensation water and prevents it from dripping.
