KROHNE OPTIBAR 5060 eDP

The OPTIBAR 5060 eDP is a dual pressure transmitter version for electronic differential pressure measurement. It is particularly suitable for level, density and DP applications with closed vessels as well as density compensated level measurement in open tanks and tanks vented to atmospheric pressure. In some applications electronic differential pressure measurement can be an alternative to the use of classical differential pressure transmitters.The main advantage of an eDP transmitter is its cost-efficient connection to the vessel. Smaller process connections without capillaries with a maximum distance of up to 25 m / 75 ft between the top and the bottom tap save cost and installation time. The electronic DP measurement loses its edge over a classical DP measurement in applications at higher gas pressures for which the classical differential pressure transmitters OPTIBAR DP 7060 or OPTIBAR DP 3050 are most suitable.

The electronic differential pressure measurement is based on two discrete gauge pressure transmitters, which are mounted in the same way as a classical differential pressure transmitter on the vessel. One transmitter, usually on the top of the vessel, acts as the secondary sensor to measure the gas pressure in the tank. The secondary transmitter is electronically connected to the primary transmitter. The primary sensor measures the gauge pressure on the very bottom of the vessel and calculates the pressure difference. In this electronic DP configuration, the secondary sensor provides fast and synchronous measurement values to the primary sensor, which acts and behaves like a classical DP transmitter in terms of setup and commissioning. The eDP transmitter can be configured with metallic or ceramic process diaphragms, granting the benefits of both technologies to the application.
