Switch Overview

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. Economical
tanks or hygienic mounting for food industry use. Direct load switching suits all supplies or
PNP output for direct interface to PLCs. For use in safe area only.

Short Fork Technology

The natural frequency (~1300Hz) of the fork is chosen to avoid interference from plant
vibration which may cause false switching. This also gives short fork length for minimal
intrusion into vessel and pipe. Using Short Fork Technology, the Rosemount 2110 is
designed for use in virtually all liquid applications. Extensive research has maximized the
operational effectiveness of the fork design making it suitable for almost all liquids, including
coating liquids (avoid bridging of forks), aerated liquids, and slurries.

Rosemount 2110 Application and Mounting Examples

For most liquids including coating and aerated liquids and slurries, the function is virtually
unaffected by flow, turbulence, bubbles, foam, vibration, solid particles, build-up or
properties of the liquid.

For use in safe area and process temperatures up to 302°F (150°C).

Mount in any position in the tank or pipe. Mounting is by
fitting.

Overfill Protection

Spillage caused by overfilling can be hazardous to people and the
environment, resulting in lost product, and clean up costs. The 2110 is a
limit level switch used to signal overfill at any time.

Pump Protection

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

Rosemount 2110

High and Low Level Alarm

Maximum and minimum level detection in tanks containing many different
types of liquids are an ideal application for the 2110. The robust 2110
operates continuously at temperatures up to 302°F (150°C) and operating
pressure up to 1450 psig (100 barg) making it perfect for use as a high or
low level alarm. It is common practice to fit an independent high level alarm
switch to provide extra back up to the level switch in case of failure.

Leak Detection

Flanges, gaskets, seals, corrosive liquids – they all have the potential to
leak at the most inconvenient times. Many users site tanks and vessels
above trays or in containments to prevent any liquids from escaping. A
level switch can quickly and accurately detect any leakage and thereby
eliminating cost.

Pump Control

Many processes have batching and header tanks, and there is usually the
need to control a pump to maintain levels between set points. These tanks
are often manufactured from thin wall materials and cannot support the
weight of heavy instrumentation.

Hygienic Applications

With the option of highly polished forks providing a surface finish (Ra)
better than 0.8 µm, the 2110 meets the principle design criteria of the most
stringent hygienic requirements used in food and beverage, and
pharmaceutical applications. Manufactured in stainless steel the 2110 is
robust enough to easily withstand steam cleaning (CIP) routines at
temperatures up to 302°F (150°C).

Application Considerations

• Ensure liquid is inside the temperature and pressure ranges (see specifications).

• Check that the liquid is inside recommended viscosity range 0.2 to 10,000 cP.

• Examples of products with too high of viscosity is chocolate syrup, ketchup, peanut
butter and bitumen. The switch will still detect these products but the drain time can be
very long.

• Check that the liquid density is above 37.5 lb/ft

• Examples of products with too low of density is acetone, pentane and hexane.

• Check for risk of build-up on the forks.

• Avoid situations where drying and coating products may create excessive build-up.

• Ensure no risk of bridging the forks.

• Examples of products that can create bridging of forks are dense paper slurries and
bitumen.

• Check if solid content in liquid

• Problems may occur if product coats and dries causing caking

• As a guideline maximum solid particle diameter in the liquid is 0.2-in. (5 mm)

• Extra consideration is needed when dealing with particles bigger than 0.2-in. (5 mm),

Installation Considerations and Recommendations

Before you install the Rosemount 2110 Level Switch, consider specific installation
recommendations and mounting requirements.

• Install in any orientation in tank containing liquid.

• Always install in the normally “on” state

• For high level recommendation is Dry = on (see “Function” on page 2-6).

• For low level recommendation is Wet = on (see “Function” on page 2-6).

• Always ensure the system is tested by using the local magnetic test point during
commissioning (see “Magnetic Test Point” on page 3-1).

• Ensure sufficient room for mounting and electrical connection (see “Dimensional
Drawing” on page A-5).

• Ensure that the forks do not come into contact with the tank wall or any internal fittings
or obstructions.

• Ensure the forks does not come into contact with the tank wall of any internal fitting.

• Avoid installing the 2110 where it will be exposed to liquid entering the tank at the fill
point.

• Avoid heavy splashing on fork

• Avoid product buildup

• Ensure no risk of bridging the forks.

• Ensure there is sufficient distance between build-up on the tank wall and the fork.

• Ensure installation does not create tank crevices around the forks where liquid may

connect (important in high viscosity and high density liquids).

• Extra consideration is needed if the plant vibration is close to the 1300 Hz operating
frequency of the 2110.

• Ensure sufficient clearance for the fork so highly viscous liquids quickly flow off the
forks.

• Extra consideration is needed if the plant vibration is close to the 1300 Hz operating
frequency of the 2110.

RELAY CONNECTION WARNING (FOR DIRECT LOAD SWITCHING)

The Rosemount 2110 requires a minimum current of 3mA, which continues to flow when the
2110 is ‘off’. If selecting a relay to wire in series with the 2110, the user must ensure that the
drop-out voltage of the relay is greater than the voltage which will be generated across the
relay coil when 3mA flows through it.

NOTE (FOR DIRECT LOAD SWITCHING)

DPST = ‘Double Pole, Single Throw’ (on/off) switch - must be fitted for safe disconnection of
the power supply. Fit the switch as near to the 2110 as possible. Keep the switch free of
obstructions. Label the switch to indicate that it is the supply disconnection device for the

2110.
