Vibration Level Switches have fault monitoring systems.

Press Release Summary:



Suited for overfill and dry run applications, OPTISWITCH 3000 and 5000 detect level of bulk solids and liquids, respectively. Both employ tuning fork as vibrating element, which is energized piezoelectrically and vibrates at mechanical resonance frequency. Unaffected by chemical and physical properties of any measured material, products utilize integrated oscillator to convert change in vibration into switching command.

KROHNE Introduces OPTISWITCH Vibration Level Switches



Highly Robust Tuning Fork Is Unaffected By Product Variations

KROHNE, Inc. a global technology leader in the development, manufacture and distribution of accurate, reliable and cost effective level and flow measurement products for the process industries, introduces its series of vibration level switches, the OPTISWITCH 3000 for the level detection of bulk solids and OPTISWITCH 5000 for the level detection of liquids. KROHNE's OPTISWITCH level switches are ideally suited for overfill and dry run applications in a wide variety of industries.

The OPTISWITCH level switches' tuning fork, the switches' vibrating element, is energized piezoelectrically and vibrates at the mechanical resonance frequency. The piezos, which are fixed mechanically, are not subject to temperature shock limitations. When the tuning fork is immersed in the liquid or solid, the vibrating frequency changes and is detected by the integrated oscillator and converted into a switching command.

As a result of its robust measuring system, the OPTISWITCH level switches are virtually unaffected by chemical and physical properties of a liquid or solid, including density, conductivity, dielectric constant and viscosity. The OPTISWITCH level switches guarantee continuous functionality when exposed to external vibrations and product variations by offering an integrated fault monitoring system. The OPTISWITCH level switches continuously monitor the possible corrosion or damage to the tuning fork, loss of vibration or line break to the piezo drive. If a fault is detected or voltage loss occurs, the OPTISWITCH level switches employ a defined switching condition, which deenergizes the relay.

Both the OPTISWITCH 3000 and 5000 series are available in a standard and extended tube version, and the OPTISWITCH 3000 series is also offered in a cable version. As a result of the wide array of processing fittings, housings and electronics, the OPTISWITCH level switches provide solutions for a variety of applications.
