Tuning fork level switches are sensors with an electrical contact output at a specific level.
Tuning fork style level sensor.
A vibrating tuning fork liquid level switch is an instrument for monitoring the height of a liquid and tripping a relay contact switch or transmitting a solid state relay switch output when a maximum minimum or intermediate level has been reached.
The oscillating frequency changes as the fork enters the medium.
Plc example with switches.
The change is analyzed and translated into a switching signal.
Rosemount 2120 level switch vibrating fork rosemount the rosemount 2120 level switch provides easy to install reliable level detection and control.
Cost effective models are an ideal choice for level control of powders and fine grained solids.
Vibrating tuning fork devices for monitoring liquid level and activating switch contacts at predetermined liquid level thresholds.
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.
For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency.
The fork paddles are only a couple of inches long and require no physical extensions in order to properly detect liquid or solid material at that point.
In solids a one rod sensor is excited at its resonant frequency.
The vibrating fork type level switch working principle is simple and effective.
The drive works piezoelectrically.
It should be noted that the previous photograph of the tuning fork style level switch is complete.
The tuning fork sensors are based on the principle of dual tuning forks which vibrate at low frequencies.
The vibrating sensor technology is perfect for solid and liquid level control including sticky materials and foam as well as powders and fine grained solids.
Models are easy to use and applications include mining chemical processing and food beverage.
The ms tech sensor r d center is currently developing novel tuning fork sensors.
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.
Threaded flanged tri grip tuning fork level switches ltu2000 series.
The scientific developments include the deposition of polymer monolayer and antibody coatings which are applied to the active surface of the sensors.
This makes vibrating fork type level switches a k a.
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.
3 rd party iec61508 sil2 safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications.
Paddle wheel level switch.
