At FSM we have more than 30 years of experience in the field of low pressure measurement for applications ranging from special machine construction, clean room monitoring to HVAC sensors. We are located in Germany and all services, including our development department and entire production, are based on site.
With experience gained from over three decades of developing transmitters and interfaces and with a strong understanding of the rapidly evolving HVAC market, we developed a new series of economical and sustainable HVAC sensors with high end performance.


A brief overview:
Up to five measured values in one device:
– Temperature, humidity, CO2, VOC and differential pressure
– High-resolution, 2.8″ TFT display
– Your own configuration via DIP switch, Bluetooth or USB
– Sustainable product concept, housing made out of 90 % castor oil-based bio-plastic
– Auto-switch function for output signals
The feel transmitter platform
Our new „feel“ transmitter platform is perfectly suited for applications where the simultaneous measurement of a wide variety of variables such as temperature, humidity, differential pressure, CO2 or VOC in a room or duct is required.
Thanks to the modular design of the device up to five measured variables can be recorded and simultaneously output. The use of the most accurate sensor element for each medium guarantees reliable precision across all measured variables. All common analogue signals and optionally an RS485 modbus interface are available. For convenient installation, a snap-in frame or a channel flange is supplied, depending on your version. Parameters such as measuring range, unit or output signal can be adapted to the on-site conditions by the user via DIP switch, Bluetooth or USB.
For easier on-site monitoring a high-resolution 2.8″ TFT display can be selected as an option.
