Failure to follow these installation guidelines could result in death or serious injury.
Make sure only qualified personnel perform the installation.
Use the Rosemount 2130 Level Switch (“level switch”) only as specified in this manual.
Failure to do so may impair the protection provided by the equipment.
The weight of the level switch with a heavy flange and extended fork length may exceed
37 lb. (18 kg). A risk assessment is required to be done before carrying, lifting, and installing
the level switch.
Explosions could result in death or serious injury.
Do not remove the level switch cover in explosive atmospheres when the circuit is alive.
The level switch cover must be fully engaged and locked to meet explosion-proof
requirements.
Verify the operating environment of the level switch is consistent with the appropriate
hazardous locations certifications.
Review Appendix B: Product Certifications for special conditions and safety instructions
associated with a hazardous location installation.
Electrical shock can result in death or serious injury.
If the level switch is installed in a high-voltage environment and a fault or installation error
occurs, high voltage may be present on the sensor leads and terminals.
Use extreme caution when making contact with the leads and terminals.
Make sure the main 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.
External surfaces may be hot.
Care must be taken to avoid possible burns. The flange and process seal may also be hot at
high process temperatures. Allow to cool before servicing.
Process leaks could result in death or serious injury.
Install and tighten process connection before applying pressure.
Do not attempt to loosen the process connection while the level switch is in service.
Make sure that the level switch is handled carefully. If the process seal is damaged, gas might
escape from the tank.
Any substitution of non-recognized parts may jeopardize safety and is under no
circumstances allowed.
Unauthorized changes to the product are strictly prohibited as they may unintentionally and
unpredictably alter performance and jeopardize safety.
Unauthorized changes that interfere with the integrity of the welds or flanges, such as
making additional perforations, compromise product integrity and safety. Equipment
ratings and certifications are no longer valid on any products that have been damaged or
modified without the prior written permission of Emerson. Any continued use of product
that has been damaged or modified without the written authorization is at the customer’s
sole risk and expense.

1.1.2 Definitions and abbreviations
The following definitions are used in this manual:
1.2 Models covered
All models of the Rosemount 2130 Level Switch -- Vibrating Fork are covered in this manual.
1.3 Level switch overview
1.3.1 Features list
The Rosemount 2130, version with 2130***E in the model number, is designed for operating in high
process temperatures of –94 to 500 °F (–70 to 260 °C).
The Rosemount 2130, version with 2130***M in the model number, is designed for operating in
mid-range process temperatures of –40 to 356 °F (–40 to 180 °C).
Based on vibrating short fork technology, the level switch is suitable for many liquid applications.
It is virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids content, coating
products, liquid properties, and product variations.
Dry(1)
1. The switching point does vary with different liquid densities (see Figure 2-3 on page 30).
The Rosemount 2130 fork (sensor) is submerged to a depth of less than 0.5 in. (13 mm).
Wet(1) The Rosemount2130 fork (sensor) is submerged to a depth of greater than 0.5 in. (13 mm).
Fault The fork frequency is outside the normal frequency band.
Normal mode The operating mode in which the Rosemount 2130 considers a 0 Hz fork frequency to
represent a wet condition (and not a fault).
Enhanced mode The operating mode in which the Rosemount 2130 considers a 0 Hz fork frequency to
represent a fault condition.

Introduction
Electronic self-checking and condition monitoring.
A ‘heartbeat’ LED indicates its operating state.
The LED also flashes when the switch output is ‘off’ and is constantly lit when 'on'.
‘Fast-drip’ fork design gives quicker response time, especially with viscous liquids. Rapid wet-to-dry
and dry-to-wet time setting for highly responsive switching
Adjustable switching delay prevents false switching in turbulent or splashing applications.
Magnetic test-point for easy functional test
No moving parts or crevices for virtually no maintenance
No need for calibration and requires minimum installation procedures
Easy terminal access and electrical protections (see “Electrical” on page 42)
Short fork length with extensions up to 157.5 in. (4 m)
General area, explosion-proof/flameproof and intrinsically safe options
SIL 2 suitable (see “Ordering information” on page 47)
This combination of features makes the Rosemount 2130 Level Switch an ideal choice for a wide variety
of challenging applications in the chemical, power generation, and oil and gas industries.
See Figure 1-2 on page 3 for application examples.
