QFM3171D Siemens Temperature Sensor
$319.87
Duct RH Sensor, 4-20mA Output Signal, 0-100% RH (Relative Humidity) Temperature, Temperature (4-20mA), Adjustable Insertion Depth (3.5 – 8 inches) Probe Length, Connection Type: Terminal Block, Display,
The QFM31xx Series Duct Sensors are used in ventilation and air conditioning buildings where high accuracy and short response times for measuring relative humidity are required. The measuring range covers the entire humidity range of 0 to 100%.
Typical installations:
- Storage and production facilities in the paper, textile, pharmaceutical, food, chemical and electronics industries, etc.
- Laboratories
- Hospitals
- Computer and EDP centers
- Indoor swimming pools
- Greenhouses
These sensors can be used as a:
- Control sensor in the supply or return air.
- Limit sensor for maximum limitation of supply air humidity after a steam humidifier.
- Limit sensor, for example, for measured value indication or for connection to a building automation and control system
Duct sensors for rel. humidity / temperature for demanding requirements
For relative humidity and temperature.
