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.

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
