  • Page 7: Chapter 1 Introduction

    Introduction Using this manual The sections in this manual provide detailed information on installing, operating, and maintaining the Rosemount 2130 Level Switch - Vibrating Fork. The sections are organized as follows: Level switch overview provides a description of the level switch and its basic principles.
  • Page 8 Introduction Reference Manual May 2022 00809-0100-4130 Reference Manual...

  • Page 9: Level Switch Overview

    Process characteristics Emerson's vibrating fork technology is virtually unaffected by turbulence, foam, solids content, coating products, and liquid properties. The natural frequency (1400 Hz) of the fork avoids interference from plant vibration that may cause false switching to a wet state.

  • Page 10: Application Examples

    Spillage caused by overfilling can be hazardous to people and the environment, resulting in lost product and potentially high clean-up costs. The Rosemount 2130 is an overfill prevention product from Emerson that can be used as one of multiple layers of protection.
  • Page 11 By selecting the option of direct load switching or relay electronics, the Rosemount 2130 is ideal for reliable pump control and can be used to protect against pumps running dry.

  • Page 12: Components Of The Level Switch

    Hygienic applications With the highly polished forks option providing a surface finish (Ra) better than 0.4 μm, the Rosemount 2130 meets the most stringent hygienic requirements used in food and beverage, and pharmaceutical applications. The Rosemount 2130 is robust enough to easily withstand CIP (Clean-In- Place) and SIP (Steam-In-Place) cleaning routines.
  • Page 13 2.5.2 Fork design The “fast drip” design allows the liquid to be quickly drawn away from the fork tip, making the Rosemount 2130 quicker and more responsive in high density or viscous liquid applications. Figure 2-2: “Fast drip” forks 2.5.3...
  • Page 14 Magnetic test point A magnetic test point is located on the side of the housing, allowing a functional test of the Rosemount 2130 and a system connected to it. Holding a magnet to the test point causes the output to change state.

  • Page 15: Chapter 3 Mechanical Installation

    In explosion-proof/flameproof and non-incendive installations, do not remove the housing cover when power is applied to the level switch. The housing cover must be fully engaged to meet flameproof/explosion-proof requirements. Rosemount 2130 Level Switch...

  • Page 16: Installation Considerations

    Before installing the level switch, review the safety, environmental, application, and pre- installation sections. 3.2.1 Environmental considerations The Rosemount 2130 is weatherproof and protected against the ingress of dust, but must be protected from flooding. Avoid installing the level switch near heat sources. Reference Manual...
  • Page 17 Figure 3-1: Environmental Considerations 3.2.2 Application considerations The Rosemount 2130 is a wired point-level device for use on open or closed vessels (tanks) and in pipework containing liquid mediums. 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 medium.
  • Page 18 Emerson. Foams In almost all cases, the Rosemount 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; known examples of this are found in ice-cream and orange juice manufacturing.
  • Page 19 37 lb. (18 kg). A risk assessment is required to be done before carrying, lifting, and installing the level switch. Use both hands to carry the extended length and high temperature versions, and do not hold a level switch by the forks (see Figure 3-4). Rosemount 2130 Level Switch...
  • Page 20 Ensure a proper seal by installing the electronics housing cover so that metal contacts metal. Always use Emerson's O-rings. Mounting orientation Mount the Rosemount 2130 at any angle that allows the level of the process medium to rise, fall, or flow through the fork gap. Reference Manual...
