Relative & Differential Pressure Transmitter - DP5-H | OMC

The **DP5-H** is a relative and differential pressure transmitter that operates on the force balance principle. It comprises two main components: the **measuring unit**, which detects variations in differential pressure using two forged bodies and a measuring capsule, and the **transmission unit**, which converts the differential force into a proportional pneumatic output signal. This output is managed by a flapper nozzle relay, which adjusts the pressure in feedback bellows until equilibrium is achieved between the bellows force and the measuring element. The transmission unit is housed in a water-resistant enclosure. The device can handle a static and differential pressure limit of up to 100 bar. Versions compliant with the ATEX Directive 2014/34/UE are available, suitable for use in Gas Zone 1 and Dust Zone 21 environments.

Description

The DP5-H 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 water-resistant housing.
