Liquid Level Gauges and Indicators

Model Types Rosemount 2120, Rosemount 2130

Product Description

Electronic level detection systems based on a tuning fork principle with switching output signals capability. , Liquid of varying densities and viscosities is either drained down past or rose up to the tuning fork resulting in a change of its resonant frequency being detected by the electronic module and the output state is switched. , A magnetic test point on the side of the housing allows functional testing to be performed when required. , The model includes four standard versions, PNP, Direct Load, Relay, Fault Relay and two intrinsically safe versions 8/16mA and Namur, all with the option of an explosion proof housing. , The encapsulated print circuit board is located in either a metal or plastic enclosure, which connects to the tuning fork sensor that forms the outer enclosure and protrudes into the process medium.
