About Vibrating Forks
Vibrating fork level switches and detectors from Emerson are ideal for all point liquid level applications.
Vibrating fork level switches and detectors from Emerson are ideal for all point liquid level applications.
This low maintenance device, designed around the tuning fork principle, provides you with point level detection for alarm, monitoring, and control.
Vibrating fork switches are reliable and perfect for overfill prevention, high and low level alarm and pump protection even in the most challenging of applications.
Emerson’s wide range of switches and detectors ensures that you will find the right device for your needs.
Rosemount 2100 Series uses vibrating fork technology. Designed around the tuning fork principle, it consists of a two-pronged fork which vibrates at its natural frequency. The frequency changes depending on the media in which it is immersed. When in air, the forks vibrate at their natural frequency. When liquid covers the forks, the frequency drops.
Changes to the frequency are continuously monitored by the switch electronics, which then change the output state to operate an alarm, pump, or valve.
The reliable vibrating fork switch is ideal for overfill prevention applications. Emerson’s Rosemount 2120, Rosemount 2130 and Rosemount 2140:SIS are all SIL 2 certifed according to IEC 61508.
Rosemount 2140:SIS has unique proof testing capabilities making the process more efficient and safe for your employees.
Many industries face tighter regulations and the hygienic sector especially. This is no issue for the Rosemount 2120 since it is 3 A and EHEDG certified. This makes it compliant to both FDA and ASME-BPE requirements and allows you to achieve compliance when cleanliness and safety are key.
The switch holds material certificates for all wetside parts and surface finish certificates for machined, polished and electro polished finishes. There are also intrinsically safe models with SIL certifications.
Rosemount 2160 combines Emerson’s wireless expertise and vibrating fork technology. It has all the features of the wired level switches and provides easy installation. No need for high infrastructure costs since the switch is totally wireless.
It communicates through Wireless HART and uses a replaceable, intrinsically safe Lithium-Thionyl Chloride power module with PBT enclosure. The battery can run for up to ten years at a one minute update rate.
