HVAC DP Transmitters for Air Overview
In air handling units, differential pressure is measured across filters, fans and coils, and between rooms. Produal's DPT range is engineered for building automation, with models for every job.
Products on this page
- DPT-2W: a 2-wire, loop-powered 4 to 20 mA transmitter with ranges from ±25 Pa, for simple wiring.
- DPT-R8: field-adjustable, multi-range transmitter with voltage and current outputs, and cold-resistant -40C models with a heating element.
- DPT-Dual-MOD: two pressure sensors and two inputs for extra sensors, all read over Modbus RTU.
- Differential pressure transmitter for AHU (DPT-Dual-MOD-AHU): two sensors with different ranges (-700 to 7000 Pa and -250 to 2500 Pa), designed for air handling units.
- DPT-Priima: high accuracy for clean rooms, ±0.4% ±0.4 Pa; the Priima-MOD adds Modbus and airflow.
- DPT-Ctrl / DPT-Ctrl-MOD: controllers that hold constant pressure or flow for fans, VAV systems and dampers.
- DPT-R8 flameproof: for hazardous areas.

FAQ
Common questions
Which transmitter suits a clean room?
The DPT-Priima, with ±0.4% ±0.4 Pa accuracy.
Can one transmitter monitor two points in an AHU?
Yes. The DPT-Dual-MOD-AHU has two pressure sensors with different ranges.
Which models work in very cold conditions?
The -40C models of the DPT-R8, which have a heating element for environments down to -40 °C.
