S+S Room, humidity and temperature sensor or measuring transducer - FSFTM-Modbus P

S+S Room, Humidity and Temperature Sensor - FSFTM-Modbus P

Introducing the latest innovation from S+S Regeltechnik GmbH, the HYGRASGARD® FSFTM - Modbus in-wall sensor and measuring transducer. This sensor is designed to accurately measure relative humidity and air temperature, as well as enable setpoint adjustment. It calculates key parameters internally such as relative humidity [% r.H.], absolute humidity [g/m³], humidity ratio [g/kg], dew point temperature [°C], enthalpy [kJ/kg] (disregarding atmospheric pressure), and room temperature [°C] with the ability to query these parameters via the convenient Modbus interface.

Technical Features

The sensor utilizes a digital, long-term stable sensor for precise humidity and temperature measurements. It is designed to be integrated into high-quality flush-mounted switch programs, with compatibility options including Gira, Berker, Merten, Jung, Siemens, or Busch-Jaeger (using an in-wall adapter, not suitable for setpoint adjustment). The sensor is suitable for non-aggressive, dust-free environments in cold, climate-controlled, and clean room technology, as well as indoor spaces like residential areas, offices, and hotels.
