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).

Developed for building automation, it enables communication between
individual units in the same system (peer-to-peer) and supports
decentralizing of control. No need for main station (master-follower).
Units receive signals directly. Supports Echelon free-topology interface
(flexible cabling and installation) and embedded I/Os and I/O options
(easy implementation of decentral I/Os). Sensor signals can quickly be
moved to another controller using bus cables. Certified as compliant
with LonMark ver. 3.4 specifications.
