DPA+

A versatile device for measuring and monitoring the overpressure, underpressure, differential pressure and volumetric flow of air and other non-aggressive gases in fans and filters in duct applications. With 8 adjustable pressure and volumetric flow ranges and high measuring accuracy, the sensor is suitable for air conditioning and ventilation applications as well as for clean room and process applications. The devices with relay outputs for a 2-point controller or a 2-stage 2-point controller and large LCD allow for a wide range of applications. Depending on the model, the sensor can be individually configured via Thermokon USEapp. Tool-free opening, closing and wiring as well as removable cable entries ensure quick and easy installation. Dual versions with 2 independent sensors for the output of 2x differential pressure and/or 2x volumetric flow are available. The mounting base (included in the delivery content) is used to mount the DPA+ on a flat surface (duct) or on DIN rail TS35 (35x7,5 mm) according to EN 60715.
