Emerson Process Managementís Rosemount 2120, 2130 and 2160 vibrating fork liquid level switches have been tested for overfill protection and certified by the German DiBt WHG approval authority. The approval means that the Rosemount level switches are included in the list of approved products published by DiBt, certified under safety devices for tanks and piping related to water pollution control.
The tests for overfill protection were successfully completed by the 3rd party tester TUV Nord (Technischer Uberwachungs-Verein), and certified by DiBt (Deutsches Institut fur Bautechnik), an authority of the German Lander Governments for a uniform fulfilment of technical tasks in the field of public law.
Proven instrument accuracy and reliability are key factors in the overfill protection approval process and the Rosemount level devices were required to pass the comprehensive test of 5000 overfill situations for each switch, over the whole temperature range.
Overfill protection devices can shut off or restrict product flow or alert the operator with an alarm when a tank is close to being full. The Rosemount 2120, 2130 and 2160 Series are designed for high and low alarms, overfill protection, pump control, including wide pressure and temperature requirements, and hygienic applications.
Rosemount 2100 Series vibrating fork level switches are suitable for a wide range of liquid applications. They are virtually unaffected by turbulence, foam, vibration, solids content, coating or liquid properties and offer a complete range of process connections, with a wide choice of housing and wetted part materials. Built-in instrument health/self-checking diagnostics, plus hazardous area options make them the ideal choice for a variety of challenging applications in many industries.
The Rosemount 2160 wireless enabled vibrating fork liquid level switch combines Emersonís wireless expertise and vibrating short fork technology. It has all the features of the wired level switches but without the complication and cost of wiring. This makes it ideal for level monitoring and control in locations previously inaccessible or too costly for wired devices.
