Differential pressure transmitter DPA+ RS485 BACnet Series

relativemembraneMEMS

Differential pressure transmitter for measuring and monitoring overpressure, underpressure, differential pressure and flow volume of air and other non-aggressive gases in fan and filter systems in duct applications. 8 adjustable pressure and flow volume ranges permit use in HVAC applications of clean rooms, process measurement and controls systems. The optional features, such as relay outputs for 2-point controllers or 2-stage 2-point controllers, an LCD with traffic light indication allow for a wide range of applications. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. 'Dual' versions with 2 independent sensors for up to 2x differential pressures or 2x flow volume in a single enclosure are available. The mounting base (included in the delivery content) can be used to mount the DPA+ on a flat surface or on DIN rail TS35 (35x7,5 mm) in accordance with EN 60715. • Application/type : Differential pressure transducer • Purpose : Measure values • Measured values : differential pressure, volume flow, pressure in Pa or inchWC, volume flow in m³/h or cfm, optionally configurable via app or uConfig • Interface : RS485 BACnet, Active, 0..5 V, 0..10 V • Configuration : USEapp, uConfig, BUS, jumper, DIP switches • Sensor : MEMS membrane measuring element • Output voltage : 2x 0..10 V or 0..5 V, adjustable via jumper, live-zero configuration via app or uConfig, min. load 10 kΩ • Network technology : RS485 BACnet (MS/TP) • Operating range humidity : max. 85% rH short term condensation
