DPT-R8 Differential pressure measurement across the heat recovery unit APPLICATIONS DPT-Flow transmitters are used to actively control air flow and maintain pressure balance. Excellent results in indoor air quality and energy savings are reached when DPT-Flow is used with temperature and air quality sensors. Demand-controlled ventilation ensures good indoor air quality and comfortable conditions for everyone. DPT-R8 transmitters are used to monitor filter and heat recovery systems. Monitoring is the key to maintaining clean filters and maximal efficiency of the heat recovery. This will reduce...

DIFFERENTIAL PRESSURE TRANSMITTERS DPT series pressure transmitters are accurate and user-friendly devices with a stylish and modern design. Fully automated zero point calibration, AZ-calibration, offers reliability in the most sensitive of applications. In addition, the AZ-calibration provides cost savings over the lifetime of a building, as it makes the device completely maintenance-free. The excellent usability of DPT-R8 series is widely known among electricians and installers all over the world. DPT-MOD and DPT-IO-MOD series Modbus transmitters can be connected on serial line and therefore...
