The DP5-A works on the force balance principle and
consists of two main units: The measuring unit which
detects the differential pressure variation and consists
of two forged bodies and a measuring capsule. 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 waterresistant housing.
