Installation and Operating Instructions - Model

1. Safety

Before installing verify compatibility to the process
media and temperature in contact with the wetted
parts. Incompatible media and / or operation at
temperature extremes
degradation of materials which could result in
safety risk to personnel.
Verify the selected pressure range (differential
pressure and working pressure) and the switch
ratings are within specification for your application.
Warning! Remaining media may result in a
risk to personnel, environment etc. Use
sufficient precautionary measures when
removing and transporting the product.

PRODUCT DESCRIPTION

The Model 130 is a differential pressure instrument
available as a switch, gauge, or both. A flexible elastomer
diaphragm and calibrated range spring are moved by
differential pressure. A magnet, coupled with the
diaphragm, transmits motion through the wall of the
pressure housing to a follower magnet attached to an
indicating pointer. The rotation of the follower magnet
causes the pointer to track movement of internal driver
magnet and indicate differential on the dial scale.
When equipped with switches for Aluminum, Brass or
316SS bodies only, a contact is made or broken by the
magnetic field of the internal magnet. See Bulletin
ELECIM130/latest for gauges with switches.
The diaphragm is totally supported upon reaching full
travel in either direction, providing full over-range
protection to rated working pressure.

INSPECTION

Before installation check the product label on each
instrument against the receiving paperwork and the
intended application for correct part number, materials
of construction, working pressure, dial range, etc. If
equipped with switches, check electrical rating, type of
enclosure, etc. Inspect for shipping damage and, report it
immediately.
