About The 2160
The Rosemount 2160 Wireless is a wireless liquid point level switch. Based on vibrating
short fork technology, the 2160 is suitable for virtually all liquid applications.
The Rosemount 2160 is 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. 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 2160 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 switch output state, along with other parameters, are regularly transmitted over a
secure wireless connection to a Smart Wireless Gateway.
The 2160 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.

General Considerations
• Handle the Rosemount 2160 with great care. Use both hands when
carrying the extended length or extreme temperature versions of the 2160
• Do not hold the 2160 using the forks
• Do not alter the 2160 in any way
Wireless Considerations
Power Up Sequence
The Power Module should not be installed on any wireless device until the
Smart Wireless Gateway (“Gateway”) is installed and functioning properly. Wireless devices
should be powered up in order of proximity from the Gateway, beginning with the closest.
This results in a simpler and faster network installation. Enabling Active Advertising on the
Gateway ensures that new devices are able to join the network faster. For more information,
see the Smart Wireless Gateway Manual (Document No. 00809-0200-4420).
Antenna Position
The antenna should be positioned vertically, either straight up or straight down, and should
be approximately 3 ft. (1 m) from any large structure, building, or conductive surface to allow
for clear communication to other devices.
Electrical Considerations
Power Module
The Rosemount 2160 is self-powered. The included power module contains two “C” size
primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of
lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials
are self-contained and are not reactive as long as the batteries and the power module are
maintained. Care should be taken to prevent thermal, electrical or mechanical damage.
Contacts should be protected to prevent premature discharge. Use caution when handling
the power module. It may be damaged if dropped from a height of 20 ft. (6,1 m).
Environmental Considerations
The Rosemount 2160 is a wireless liquid
level switch, and is Intrinsically Safe (IS)
approved for hazardous area
installations. Approvals are listed in
“Product Certifications” on page 14.
The 2160 is designed for open or closed
tank and pipe installation. It is
weatherproof and protected against the
ingress of dust, but must be protected
from flooding. Avoid installing the 2160
near heat sources. OKOK

Installation Considerations
•Battery Side of Electronics Housing
Mount the switch so that the battery side is accessible. Clearance of 23/8in. (60 mm) is
required for cover removal.
•Circuit Side of Electronics Housing
Provide 0.75 in. (19 mm) of clearance for units without an LCD display. Three inches of
clearance is required for cover removal if an LCD display is installed.
•Cover Installation
Always ensure a proper seal by installing the electronics housing cover(s) so that metal
contacts metal. Use Rosemount O-rings.
•LCD Rotation
The optional LCD display can be rotated in 90°increments by squeezing the two tabs,
pulling out, rotating and snapping back into place. If LCD pins are inadvertently removed
from the interface board, carefully re-insert the pins before snapping the LCD display
back into place.
•Grounding
Always ground the housing in accordance with national and local electrical codes. The
most effective grounding method for the housing is a direct connection to earth ground
with minimal impedance.
•Housing Rotation
The housing can be rotated for optimal viewing of the optional LCD display and to get
the best antenna position. Perform the following procedure:
1. Loosen the housing rotation set screw
(Figure 3-2).
2.First rotate the housing clockwise to the
desired location. If the desired location cannot
be achieved due to the thread limit (up to 360°),
rotate the housing counter-clockwise to the
desired location. Do not over twist.
3.Re-tighten the housing rotation set screw.
Installation Recommendations
•Avoid installing near liquid
entering the tank at the fill point
•Avoid heavy splashing
on the forks
•Ensure the forks do not come
into contact with the tank or pipe
wall, or internal fittings
•Ensure there is sufficient
distance between build-up on
the tank wall and the fork
•Ensure the installation does not
produce crevices for product
build-up around the forks
