    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 Rosemount 2110 is in  service. Electrical shock could cause death or serious injury.

  • Page 8: Manual Overview

    Introduction to the Rosemount 2110 The Rosemount 2110 is a liquid point level switch based on the vibrating short fork technology. It is a compact switch with a rugged stainless steel body and forks for use in a wide range of liquid applications.

  • Page 9: Measurement Principle

    When the Rosemount 2110 is used as a high level alarm, the liquid rises in the tank or pipe making contact with the fork and causing the output state to switch.

  • Page 10: Special Features

    Heartbeat LED The Rosemount 2110 has a ‘heartbeat’ LED indicating it is operating, and can be seen at all times. The LED flashes when the switch output is ‘off’ and is constantly lit when 'on'. 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 Rosemount 2110 and the system connected to it.

  • Page 11: Product Recycling And Disposal

    Short forks require minimum intrusion wetside and allow simple low cost installation at any angle into pipes or vessels. Because the Rosemount 2110 projects only 2-in. (50 mm) (depending on connection type), it can be installed in small diameter pipes. By selecting the option of direct load switching electronics, it is ideal for reliable pump control and can be used to protect against pumps running dry.

  • Page 14: Considerations Before Installation

    2.2.1 Environmental considerations The Rosemount 2110 Level Switch is a wired point level device for use in open or closed tanks, and pipework. The installation must be in a non-hazardous (safe) area. All versions of the level switch are weatherproof and protected against the ingress of dust, but must be protected from flooding.
  • Page 15 Reference Manual Configuration 00809-0100-4029, Rev CA March 2018 Application limits Check for risk of process medium build-up on the level switch forks.  Avoid situations where a drying and coating process medium may create an excessive build-up (see Figure 2-2 on page 9) or implement preventative maintenance programs to ensure the build-up is not enough to impair performance.

    For direct load switching, a DPST (Double Pole, Single Throw) (on/off) switch must also be fitted for safe disconnection of the power supply. Fit the DPST switch as near to the Rosemount 2110 as possible, keeping the switch free of obstructions. Label the switch to indicate it is the supply disconnection device for the Rosemount 2110.
  • Page 25 The Rosemount 2110 requires a minimum current of 3 mA, which continues to flow when it is ‘off’. When selecting a relay to wire in series with the Rosemount 2110, the drop-out voltage of the relay must be greater than the voltage generated across the relay coil when 3 mA flows through it.
