ACCESSORIES FOR FITTING TRANSMITTERS

TYPES OF ISOLATING VALVES 

Manifold

The manifold is quite simply an assembly of isolating valves on a same block. Its main job is to isolate a pressure transmitter so that its zero can be calibrated.

Types of Manifold

2-way manifolds

    The 2-way manifold is used for "conventional" pressure transmitters. It has a transmitter HP isolating valve and a drain valve. This type of manifold is very rarely used.

3- and 5-way manifolds

    The 3- and 5-way manifolds are much used in the instrumentation field, they connect directly to the differential pressure transmitters. The 3-way manifold combines the isolating and bypass functions.

The manifold and its associated transmitter

In this example, the manifold is mounted directly on the transmitter by means of screws supplied with the manifold.
