SAFETY MESSAGES Procedures and instructions in this manual may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a caution symbol ( ). The
external hot surface symbol ( ) is used when a surface is hot and care must
be taken to avoid possible burns. If there is a risk of an electrical shock the
( ) symbol is used. Refer to the safety messages listed at the beginning of
each section before performing an operation preceded by this symbol.
CAUTION
Failure to follow these installation guidelines could result in death or serious injury.
• The Rosemount 2130 is a liquid level switch. It must be installed, connected,
commissioned, operated, and maintained by suitably qualified personnel only,
observing any national and local requirements that may apply.
• Ensure the wiring is suitable for the electrical current and the insulation is suitable for
the voltage, temperature, and environment.
• Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment
Explosions could result in death or serious injury
• Verify that the operating environment of the liquid level switch is consistent with the
appropriate hazardous area locations
External Surface may be hot.
• Care must be taken to avoid possible burns.
Process leaks could result in death or serious injury.
• Do not remove the liquid level switches while in operation. Removing while in operation
may cause process fluid leaks.
Electrical shock could cause death or serious injury.
• If the liquid level switch is installed in a high voltage environment and a fault condition
or installation error occurs, high voltage may be present on switch leads and terminals.
• Use extreme caution when making contact with the leads and terminals.
• Make sure that power to the liquid level switch is off while making connections.

SWITCH OVERVIEW The Rosemount 2130 Extreme Temperature Vibrating Fork Level Switch is
designed for use in extreme temperatures. Based on vibrating short fork
technology, the 2130 is suitable for virtually all liquid applications.
Features include:
• Virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids
content, coating, properties of the liquid, and product variations
• Operation in extreme temperatures of –94 to 500 °F (–70 to 260°C)
• No need for calibration and requires minimum installation procedures
• Easy terminal access, polarity insensitive, and short-circuit protection
• No moving parts or crevices means virtually no maintenance
• Electronic self-checking and condition monitoring. The heartbeat LED
gives status and instrument health information
• Adjustable Switching Delay for turbulent or splashing applications
• Magnetic test point for easy functional test
• Short fork length with extensions up to 118 in. (3 m)
• “Fast Drip” fork design gives quick response time
• General area, Explosion-proof/Flameproof, and Intrinsically Safe
options
This combination of features makes the 2130 an ideal choice for a wide
variety of challenging applications in the chemical, power generation, and oil
and gas industries.
CAUTION
Any substitution of non-recognized parts may jeopardize safety and is under no
circumstances allowed.

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
