Rosemount Liquid Level Switch


The Rosemount Liquid Level Switch is designed using the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency. 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. When 2110 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.

Features and Benefits


Materials of construction is 316/316L Stainless Steel (1.4401/1.4404) dual certified

Process connection size is 1in BSPT (R) thread

Relay DPCO, 20 to 264 Vac 50/60Hz, 20 to 60 Vdc

Standard surface finish

Housing has glass filled nylon and M20 conduits/cable threads

Fork length is standard length of 1.7in (44 mm)

Function virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids content, coating products, liquid properties, and product variations

Operation temperatures ranges from –40°C and 150°C

A ’heartbeat’ LED indicates its operating state, LED also flashes when the switch output is ’off’ and is constantly lit when 'on'

Adjustable switching delay prevents false switching in turbulent or splashing applications

’Fast drip’ fork design gives quicker response time, especially with viscous liquids

Rapid wet-to-dry and dry-to-wet time setting for highly responsive switching

Fork shape is optimized for polishing to meet hygienic requirements

Mechanical- and electro-polishing options

Magnetic test point makes functional test easy

No moving parts or crevices for virtually no maintenance

Specific extended fork length is factory default length (only if Fork Length A or H is selected)

Applications


Overfill protection

High and low point level alarms

Pump control or limit detection

Run dry or pump protection

Hygienic applications

High-temperature applications

Wireless applications

Most liquids including coating liquids, aerated liquids, and slurries

Certifications


ATEX Intrinsic Safety
