Description

Indoor Air Quality Differential Pressure-Fow Transmitter. Optional with IQnexus LoRaWAN® ModBus Transceiver. The Thermokon Transmitters and Sensors are available with different interfaces like BACnet MS/TP, 4-20 mA or ModBus RTU. Contact us for the different versions.

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. Depending on the model, the DPA+ can be individually configured via Thermokon USEapp. 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.

The DPA250+ is communicating via ModBus RTU. The connected IQnexus LoRa® ModBus Transceiver is reading the ModBus Registers as a master and packs the register data into LoRaWAN® payloads.
