Tuning Fork Style Level Sensor

It should be noted that the previous photograph of the tuning fork style level switch is complete.

Tuning fork style level sensor.

For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. The change is analyzed and translated into a switching signal. This low maintenance device designed around the tuning fork principle provides you with point level detection for alarm monitoring and control. The vibrating fork type level switch working principle is simple and effective.

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. Threaded flanged tri grip tuning fork level switches ltu2000 series. 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. The ms tech sensor r d center is currently developing novel tuning fork sensors.

Models are easy to use and applications include mining chemical processing and food beverage. 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. This makes vibrating fork type level switches a k a. The scientific developments include the deposition of polymer monolayer and antibody coatings which are applied to the active surface of the sensors.

The ltu 2000 tuning fork sensors are point level switches that are designed to detect low or high levels of liquids and is based on the vibrating tuning fork principle. The oscillating frequency changes as the fork enters the medium. In solids a one rod sensor is excited at its resonant frequency. Vibrating tuning fork devices for monitoring liquid level and activating switch contacts at predetermined liquid level thresholds.

The tuning fork sensors are based on the principle of dual tuning forks which vibrate at low frequencies. The drive works piezoelectrically.
