The HG808-T is an industrial-grade super high temperature 200℃, humidity, and dew point transmitter designed for harsh environments with high temperatures.
In addition to measuring and transmitting temperature and humidity, the HG808-T calculates and transmits the dew point, which is the temperature at
which air becomes saturated with water vapor and condensation begins to form.
Here’s a breakdown of the key features:
*Temperature range: -40 ℃ to 200 ℃ (-40 °F to 392 °F)
*Probe: The transmitter is equipped with a high-temperature probe that is waterproof and resistant to fine dust.
*Output: The HG808 offers flexible output options for temperature, humidity, and dew point data:
Standard industrial interface RS485 digital signal
4-20 mA analog output
Optional: 0-5v or 0-10v output
*Display: The transmitter has an integrated display for viewing temperature, humidity, and dew point readings.
*Connectivity: The HG808 can be connected to various industrial control systems, including:
On-site digital display meters
PLCs (Programmable Logic Controllers)
Frequency converters
Industrial control hosts
✔ industrial sensors for applications up to 200°C
✔ IP 65
✔ for measuring relative humidity and temperature
✔ with porous metal humidity sensing element
✔ with current or voltage output
Designed for use in industrial process automation, the sensors of the HG808-T relative humidity temperature sensor can be installed in virtually any position. The robust devices are available to be mounted in ducts, on walls, or are available with a stainless steel probe that can be up to 5 m away from the output electronics. Depending on the application, we either recommend using transmitters with exchangeable or permanently assigned probes. The type of filters and filter materials can be adapted to suit the respective protection category required (up to IP65).
All devices work with an internal processor which uses the measured values for relative humidity and temperatures to also calculated absolute humidity, mixture ratio (water/air) or the dew point (can choose). Digitalization of the signal processing allows the measurement accuracy for humidity to reach excellent values of ±2.0% RH, and with the platinum resistance sensor, the accuracy of the temperature measurement reaches tolerances of ±0.3℃. Depending on the individual design, the sensors can be used at temperatures of between 0 °C and +200 °C and at pressures of up to 10 bar in non-corrosive air.
