The DP5-R works on the force balance principle and consists of two main units: The measuring unit which detects the pressure variation and consists of two forged bodies and a bellows. The transmission unit converts the differential force applied to the measuring element into a proportional output pneumatic signal. The output pressure, generated by a flapper nozzle relay, feeds the feedback bellows with a rising pressure until the balance between bellows force and measuring element is reached. The whole transmission unit is contained within a water-resistant housing.
