NOTICE
This installation guide provides basic guidelines for the Rosemount 2130. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the Rosemount 2130 Reference Manual
Emerson.com/Rosemount
Failure to follow these installation guidelines could result in death or serious injury.
The Rosemount 2130 Vibrating Fork Level Switch (“level switch”) 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. Failure to do so may impair the protection provided by the
equipment.
Any substitution of non-recognized parts may jeopardize safety and is under no circumstances allowed.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.
Installation of the level switch in a hazardous environment must be in accordance with the appropriate
local, national, and international standards, codes, and practices. Please review the Product Certifications section for any restrictions associated with a safe installation
Verify that the operating atmosphere of the level switch is consistent with the appropriate hazardous
locations certifications.
External surface may be hot.
Care must be taken to avoid possible burns.
Process leaks could result in death or serious injury.
Install and tighten process connectors before applying pressure.Do not attempt to loosen or remove process connectors while the level switch is in service.
Electrical shock could cause death or serious injury.
If the level switch is installed in a high voltage environment and a fault condition or installation error
occurs, high voltage may be present on leads and terminals.
Use extreme caution when making contact with the leads and terminals.Make sure that power to the level switch is off while making connections.

1.0 Introduction

1.1 Overview of the Rosemount 2130

The Rosemount 2130 Level Switch (“level switch”) uses vibrating short fork technology, and is suitable for virtually all liquid applications.
The level switch is designed using the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency (~1400 Hz). Changes to this frequency are continuously monitored. The frequency of the vibrating fork sensor changes depending on the medium in which it is immersed. The denser the liquid, the lower the frequency.
When used as a low level alarm, the liquid in the tank or pipe drains down past the fork, causing a change of natural frequency that is detected by the electronics and switches the output state to a dry condition. When the level switch is used as a high level alarm, the liquid rises in the tank or pipe, making contact with the fork which then causes the output state to switch to a wet condition.
The level switch 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. The level switch has a ‘heartbeat’ LED that indicates its operating state. The LED flashes when the switch output is ‘off’ and is constantly lit when 'on'.

2.0 Before installation

2.1 General considerations

The weight of the Rosemount 2130 Level Switch (“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.
Handle the level switch with great care (Figure 2).
Figure 2. Handling the Rosemount 2130
OK OK
The level switch is available as intrinsically safe or explosion-proof/flameproof
versions for hazardous area installations (see page 19 for approvals). There are ordinary location versions of the level switch for unclassified, safe areas.
This level switch is designed for open or closed tanks, and pipe installation. It is
weatherproof and protected against the ingress of dust, but must be protected from flooding (Figure 3). The 2130***E operates in extreme process temperatures of –94 to 500 °F (–70 to 260 °C), and the 2130***M operates in mid-range process temperatures of –40 to 356 °F (–40 to 180 °C).

Figure 3. Environmental Considerations
July 2017
Ensure there is adequate space outside the tank or pipe. A clearance of 1.2 in.
Quick Start Guide
(30 mm) is required for the housing cover to be removed.
Always ensure a proper seal by installing the electronics housing cover so that
metal contacts metal. Use Rosemount O-rings.
Always ground the housing in accordance with national and local electrical
codes. The most effective grounding method is a direct connection to earth (ground) with minimal impedance. Use the fork earth for housings with NPT conduit entries.

2.2 Installation recommendations

Avoid installing near liquid entering the tank at the fill point.Avoid heavy splashing on forks. Increasing time delay reduces accidental
switching.
Avoid installing near heat sources.Ensure the forks do not come into contact with the tank/pipe wall or fittings.Allow a distance between product build-up on the tank wall and the fork
(Figure 4).

3.0 Physical installation

1. Install the level switch according to standard installation practices, making sure to correctly align the fork using the alignment notch or groove (Figure 5).
2. Use supports for extended fork lengths greater than 3.2 ft. (1 m). Refer to the Rosemount 2130 Reference Manual
3. Close the housing cover and tighten to safety specification. Always ensure a proper seal so that metal touches metal, but do not over tighten.
4. Insulate the level switch with ROCKWOOL
