Figure 1-1.
Features of the 2130
Measurement Principle The Rosemount 2130 is a liquid point level switch, designed using the
principle of a tuning fork. A piezo-electric crystal oscillates the forks at their
natural frequency. Changes to this frequency are continuously monitored.
When used as a low alarm, the liquid in the vessel drains down past the fork,
causing a change of natural frequency that is detected by the electronics and
switches the output state.
When the 2130 is used as a high alarm, the liquid rises in the vessel making
contact with the fork causing the output state to switch.
Short Fork Technology The natural frequency (~1300Hz) of the fork avoids interference from plant
vibration that may cause false switching. This allows for minimum intrusion
into the vessel or pipe through the use of a short fork.
Using Short Fork Technology, the Rosemount 2130 can be used in almost all
liquid applications. Extensive research has maximized the operational
effectiveness of the fork design, making it suitable for most liquids including
coating liquids (avoid bridging of forks), aerated liquids, and slurries.
Special Features Mode Switch and Adjustable Time Delay
A mode switch allows the 2130 to be set to switch from wet-to-dry (typically
for low level alarm) or from dry-to-wet (typically for high level alarm).
There is also a user-selectable time delay of 0.3, 1, 3, 10, or 30 seconds.
Increasing the time delay in turbulent or splashing applications virtually
eliminates the risk of false switching.

Heartbeat LED
The 2130 has a ‘heartbeat’ LED that indicates status. The LED flashes when
the switch output is ‘off’ and is constantly lit when 'on'. The LED constantly
indicates that the 2130 is functioning correctly.
Magnetic Test Point
A magnetic test-point is located on the side of the housing, allowing the user
to perform a functional test of the 2130 and the system connected to it.
Holding a magnet to the test-point causes the output to change state.
Instrument Health Monitor and Continuous Self-Check
The 2130 continuously performs instrument health diagnostics to self-check
the condition of the fork and sensor. These diagnostics can detect damage to
the forks including corrosion, internal or external damage to the forks, and
breakages to the internal wiring. Any of these conditions will trigger the
'heartbeat' LED to pulse intermittently, followed by safe handling of the
electrical load.
Electrical Hookup
The terminal blocks extend above the housing and give easy terminal access.
The polarity insensitivity and short-circuit protection make electrical hook-up
safe and easy.
Fork Design
The “fast drip” fork design draws liquid away from the fork tips, and together
with a short switching delay, allows the 2130 to react quickly and with greater
sensitivity to density variations.
ROSEMOUNT 2130
APPLICATION
EXAMPLES
For most liquids, including coating, aerated liquids and slurries, the function is
virtually unaffected by flow, turbulence, bubbles, foam, vibration, solid
particles, build-up, or properties of the liquid.
See Figure 1-2 on page 1-6 for application examples.
The 2130 can be used in Hazardous (IS or Exd) or non-hazardous (safe)
areas but supports higher process temperatures up to 500 °F (260 °C).
The 2130 can be mounted in any position in a tank or pipe. There is a wide
range of threaded, flanged, or hygienic connections.
Application Considerations:
• Ensure the process is operating within the temperature and pressure
ranges (see “Specifications” on page A-1)
• Ensure the liquid viscosity is within the recommended viscosity range
(see “Specifications” on page A-1)
• Check that the liquid density is higher than 37.5 lb/ft3 (600 kg/m3), or
above 31.2 lb/ft3 (500 kg/m3) when ordered with the Low Density
Range option (see “Specifications” on page A-1)
• Check for risk of build-up on the forks
Avoid situations where drying and coating products may create
excessive build-up
• Ensure there is no risk of bridging the forks

Reference Manual
00809-0100-4130, Rev AA
May 2009
1-5
Rosemount 2130
Examples of products that can create bridging of forks are dense paper
slurries and bitumen
• Check the solids content in the liquid
As a guideline, the maximum solid particle diameter in the liquid is
0.2 in. (5 mm)
Extra consideration is needed when dealing with particles bigger than
0.2 in. (5 mm). Consult the factory for advice.
• Problems may occur if product coats and dries causing caking.
• In almost all cases, the 2130 is insensitive to foams (i.e. does not see
the foam).
However in rare occasions, some very dense foams may be seen as
liquid; a known example of this is found in ice-cream and orange juice
manufacturing.

Overfill Protection
Spillage caused by overfilling can be hazardous to people and the environment, resulting in
lost product and potentially high clean up costs.
High and Low Level Alarm
Maximum and minimum level detection in tanks containing different types of liquids are ideal
applications. The Rosemount 2130 is robust and operates continuously across the
temperature range of –94 to 500 °F (–70 to 260 °C) and operating pressures of up to 1450 psig
(100 barg), making it perfect for use as a high or low level alarm. It is common practice to have
an independent high level alarm switch as a backup to an installed level device in case of
primary failure.
Pump Control (Limit Detection)
Batch processing tanks often contain stirrers and agitators to ensure mixing and product
‘fluidity’. The standard user selectable time delay, from 0.3 to 30 seconds, virtually eliminates
the risk of false switching from splashing.
Pump Protection or Empty Pipe Detection
With the fork projecting only 2 in. (50 mm) (dependant on connection type), the 2130 can be
installed in small diameter pipes. Short forks mean minimum intrusion on the wetside and
allow for simple, low cost installation at any angle into your pipes or vessels. By selecting the
option of direct load switching electronics, the 2130 is ideal for reliable pump control and can
be used to protect against pumps running dry.
Extreme Temperature Applications
The 2130 is designed for extreme temperatures and is suitable for continuous operation within
the temperature range of –94 to 500 °F (–70 to 260 °C).
Wireless Applications
The advent of wireless communications allows process plant managers to save up to 90% on
installation cost compared with wired technologies. More data can be collected at central
locations than has ever been possible before. The 2130 can be used with a Rosemount 702
Wireless Transmitter to enable these benefits for your applications.
Hygienic Applications
With the highly polished forks option providing a surface finish (Ra) better than 0.8 µm, the
2130 meets the most stringent hygienic requirements used in food and beverage, and
pharmaceutical applications. Manufactured in stainless steel, the 2130 is robust enough to
easily withstand steam cleaning (CIP) routines for temperatures up to 500 °F (260 °C).

INSTALLATION
CONSIDERATIONS AND
RECOMMENDATIONS
Before you install the Rosemount 2130, consider specific installation
recommendations and mounting requirements:
• Install in any orientation in tank containing liquid
• Always install in the “on” state
(See “Electrical Installation” on page 6)
• For a high level, use the “Dry on” setting
• For a low level, use the “Wet on” setting
• Ensure the system is tested by using the local magnetic test-point
during commissioning. (See “Magnetic Test Point” on page 3-2)
• Ensure there is sufficient room for mounting and electrical connections
(see “Dimensional Drawings” on page A-5 for switch dimensions)
• Avoid installing the 2130 near to liquid entering the tank at the fill point
• Avoid heavy splashing on the forks. Increasing the time delay reduces
accidental switching caused by splashing
• Ensure that the forks do not come into contact with the tank wall, any
internal fittings, or obstructions
• Ensure there is sufficient distance between build-up on the tank wall
and the fork (see Figure 1-6 on page 1-8)
• Ensure the installation does not create tank crevices around the forks
where liquid may collect. This can happen with high viscosity and high
density liquids
• Extra consideration is needed if the plant vibration is close to the
1300 Hz operating frequency of the 2130
• Supporting the fork avoids long fork length vibration
(see Figure 1-7 on page 1-9
