The core element of the vibrating level switch is the vibrating fork with integrated vibration drive. When the vibrating tuning fork is immersed in the medium, the resonance frequency of the tuning fork decreases. The frequency change is detected by the electronic circuit and is converted to a switching signal. Irrespective of the mounting position, level changes can be detected very accurately.
The respective switch point can be changed via a pipe extension. The TLS-C vibrating level switch is specially designed for industrial applications and offers reliable point level detection. It is ideal for monitoring bilges and leaks as well as for point level detection in oil tanks of rotor gearboxes.
The vibrating level switches are, depending on the version, suitable for an operating temperature of -40 ... +150 °C [-40 ... +302 °F] and an operating pressure of -1 ... +64 bar [-14 ... +928 psi]. The vibrating level switch is suitable for media with a density of 500 ... 2,500 g/cm3 [289 ... 1,445 oz/in3]. The viscosity of the media should be between 0.1 and 10,000 cP [0.24 and 21,190 lb/ft·h].
