Tuning Fork Style Level Sensor

Paddle wheel level switch.

Tuning fork style level sensor.

Tuning fork level switches are sensors with an electrical contact output at a specific level. Rosemount 2120 level switch vibrating fork rosemount the rosemount 2120 level switch provides easy to install reliable level detection and control. This makes vibrating fork type level switches a k a. For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency.

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. Cost effective models are an ideal choice for level control of powders and fine grained solids. The ms tech sensor r d center is currently developing novel tuning fork sensors. Tuning fork type level switches reliable cost effective and very popular for use in detecting the presence or absence of liquids and bulk solid materials.

It should be noted that the previous photograph of the tuning fork style level switch is complete. 3 rd party iec61508 sil2 safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. Threaded flanged tri grip tuning fork level switches ltu2000 series. However the types of applications that can use tuning forks is limited to overfill or run dry type applications and they do not provide continuous process measurement.

The scientific developments include the deposition of polymer monolayer and antibody coatings which are applied to the active surface of the sensors.
