Installation
November 2016
Process leaks could result in death or serious injury.
Install and tighten all four flange bolts before applying pressure.

Do not attempt to loosen or remove flange bolts while the Rosemount ERS System is in service.

Replacement equipment or spare parts not approved by Emerson

reduce the pressure retaining capabilities of the transmitter and may render the instrument
dangerous.
Use only bolts supplied or sold by Emerson as spare parts.

Improper assembly of manifolds to traditional flange can damage the device.
For the safe assembly of the manifold to the sensor flange, bolts must break the back plane of the

flange web (i.e. bolt hole) but must not contact the sensor module.
Static electricity can damage sensitive components.
Observe safe handling precautions for static-sensitive components.

Models covered

The Rosemount ERS System is a flexible, 2-wire HART architecture that calculates differential pressure
(DP) electronically, using two pressure sensors. The pressure sensors are linked together with an
electrical cable and synchronized to create a single Rosemount ERS System. The sensors used in the
Rosemount ERS System can consist of any combination of Rosemount 3051SAM and 3051SAL models.
One of the sensors is required to be a "Primary" and the other is required to be a "Secondary."
The Primary sensor contains the 4–20 mA loop termination and optional LCD display. The Secondary
sensor is made up of a pressure sensor module and junction box housing that is connected to the
primary sensor, using a standard instrument cable.
