WARNING
Failure to follow safe installation and servicing guidelines could result in death or serious injury.
Ensure the level switch is installed by qualified personnel and in accordance with applicable code of practice.
Use the level switch only as specified in this manual. Failure to do so may impair the protection provided by the level switch.
The weight of a level switch with a heavy flange and extended fork length may exceed 37 lb. (18 kg). A risk assessment is required
before carrying, lifting, and installing the level switch.
WARNING
Explosions could result in death or serious injury.
Verify the operating atmosphere of the level switch is consistent with the appropriate hazardous locations certifications.
Before connecting a handheld communicator in an explosive atmosphere, ensure the instruments are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
In explosion-proof/flameproof and non-incendive installations, do not remove the housing cover when power is applied to the
level switch.
The housing cover must be fully engaged to meet flameproof/explosion-proof requirements.
WARNING
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock.
Ensure the power to the level switch is off, and the lines to any other external power source are disconnected or not powered while
wiring the level switch.
Ensure the wiring is suitable for the electrical current and the insulation is suitable for the voltage, temperature, and environment.
WARNING
Process leaks could result in death or serious injury.
Ensure the level switch is handled carefully. If the process seal is damaged, gas might escape from the vessel (tank) or pipe.

WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could

Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access
by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

1.1 About this document
This document provides information about how to install, commission, and proof test a
Rosemount 2130 Level Switch to comply with Safety Instrumented Systems (SIS)
requirements.

1.2 About this product
The Rosemount 2130 Level Switch consists of a tuned fork with a driver and receiver
element, and integral interface electronics. The level detector is based on the principle
that the resonant frequency of a tuned fork changes when it is immersed in a liquid. The
frequency change is detected and used to switch an electrical output.
A range of output options are available to suit different applications.
