DUCT HUMIDITY-, TEMPERATURE- AND PRESSURE SENSORS ±500PA-MB
Maintenance-free duct sensor covering humidity, temperature and pressure
in one transducer. Microprocessor-controlled with Modbus RTU connection
in a resistant IP65 plastic housing with quick-locking screws and M16
cable gland for cable connection. Including mounting flange to detect
the relative humidity (0…100% RH) and the temperature (–35...+80 °C)
inside a tube, with an exchangeable plastic sinter filter. A
differential air pressure (max. ± 500 Pa) with connection nozzles for
pressure hose (Ø 6 mm). The duct sensor is applied in a non-aggressive
and dust-free environment and is suitable for installation in ceilings,
ducts and devices. International SI units (default) can be switched to
Imperial (via Modbus).
