Room pendulum temperature measuring transducer THERMASGARD® RPTM 2 - Modbus
Calibratable THERMASGARD® RPTM 2 - Modbus resistance thermometre with globe THERMASGARD® RPTM 2 - Modbus with Modbus connection, terminal box housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display for indicating the actual temperature.
The pendulum room sensor is specifically designed for temperature detection in larger rooms or halls, for example, as a dark radiation sensor. In combination with the positioning of the pendulum sensor in the room and the unform flow of ambient air around the sensor, the measuring method employed by the device delivers excellent measuring results representative of the room. The globe thermometres determine the effective portion of active radiation or the effective radiant heat at the measured location. The globe temperature is determined in order to take heat radiation into consideration and to estimate the degree of thermal comfort (operative room temperature). The operative room temperature describes the co-action of heat radiation and heat convection (the globe/air temperature ratio is approx. 70% to 30%). The sensors are factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable).
