ScopeEnvironmental measurement
Engineering position
Temperature and humidity transmitter with local display and psychrometric calculation for environmental measurement
The product measures or communicates environmental temperature and relative humidity for building, laboratory, storage and controlled-environment systems. These products support environmental-condition monitoring; airborne-particle classification, continuous particle counting and HEPA-filter integrity testing require separate contamination-control instrumentation. Environmental transmitter combining temperature/RH measurement, local display, RS485, analogue outputs and calculated psychrometric properties.
Temperature measurementConfirm measurement range, mounting position, response requirements and calibration expectations.
Relative-humidity measurementConfirm RH range, condensation exposure, calibration expectations and installation airflow.
System integrationSelect analogue, RS485, wireless or cloud integration according to the data consumer and network architecture.
Current product position: Current RHT Climate positioning combines local display, RS485 Modbus RTU, configurable analogue outputs and psychrometric calculations for environmental/HVAC integration.
System role
RHT Climate signal and system architecture
The architecture separates the field/process interface, the NOVUS function and the downstream control or information path. Exact electrical interfaces, protocol roles and accessories remain model-dependent.
