- Stable and reliable level detection without interference from flow, bubble formation, vibrations, build-up or solids in the medium
- Suitable for SIP and CIP
Description
The core element of the vibrating level switch is the tuning 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 model TLS-H vibrating level switch offers reliable and precise level detection. The instrument has been designed in accordance with the requirements of hygienic processes and enables easy cleaning and maintenance. The TLS-H in hygienic design can be used for CIP (cleaning in place) and SIP (sterilisation in place). It is available with two electrical outputs: TLS-HC with ASC4 connector and TLS-HM with M12 connector ─ for optimal adaptation to different system configurations.
In addition, the TLS-H is available with different surface roughnesses to meet the specific requirements of the respective application. A large number of hygienic process connections enables easy integration into food and pharmaceutical processes.
The vibrating level switches are, depending on the version, suitable for a process 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 ... 10,000 cP [0.24 and 21,190 lb/ft·h].
