Product information "JUMO hydroTRANS S20 "
Combined transmitter from the JUMO brand for humidity and temperature measurement for wall mounting
JUMO hydroTRANS S20 – Humidity and temperature transmitter with display Type: 907042/11-0-15-009/994
This version of the JUMO hydroTRANS S20 with integrated display is a humidity and temperature transmitter for monitoring indoor air quality. With configurable output signal, multisensor system, and direct display, it is particularly suitable for air conditioning, ventilation, and building technology as well as storage monitoring.
The JUMO hydroTRANS S20 in this version is a combined transmitter for measuring relative humidity and temperature and was developed for the continuous monitoring of ambient air in indoor areas as well as protected outdoor environments. Thanks to wall mounting, the device can be flexibly integrated into climate and building systems.
Technical data
- Basic type extension: RH-T
- Version: Standard
- Measuring range: 0 … 100 % RH / -40 … +80 °C
- Measured parameters: relative humidity, temperature
- Output: 4–20 mA / 0–10 V (combined output configurable)
- Type addition: with integrated display
Advantages and technical features of the JUMO hydroTRANS
- Combined measurement of humidity and temperature in one device
- Integrated display for direct on-site reading
- Wide measuring range up to 100 % RH and -40 to +80 °C
- Flexible combined output (4–20 mA / 0–10 V configurable)
- Easy wall mounting for quick installation
The measuring range covers 0 to 100 % relative humidity as well as temperatures from -40 to +80 °C, covering a wide range of applications in room and process climate control. The measured values are provided via a configurable combined output (4–20 mA or 0–10 V), enabling flexible adaptation to different control and regulation concepts.
This variant is equipped with an integrated display, allowing measured values to be read directly on the device. This simplifies on-site monitoring and makes additional readout devices unnecessary in many cases.
The device operates with a multisensor system for the simultaneous acquisition of humidity and temperature values. Optionally, a plastic sinter filter can be used to protect the sensor from dust and particles, thereby supporting measurement stability in more demanding environments.
Typical areas of application
- Climate monitoring in buildings
- Ventilation and air conditioning systems
- Building management systems
- Storage rooms and archives
- Technical rooms and production environments
- Protected outdoor areas
