Level Sensors with Reed Switch Chain Technology Model RMG

Transcription

1 Level Measurement Level Sensors with Reed Switch Chain Technology Model RMG Applications Level measurement for almost all liquid media Chemical industry, petrochemical industry, natural gas, ting equipment, power stations Process water and drinking water treatment, food and Special Features Operating limits: - Operating temperature: T = C - Limit S. G.: 3 connections and materials, Explosion-protected versions Description serve as measuring transducers for level measurement in transmission. potentiometer circuit. The measurement voltage generated the contact separation of the measuring chain and is thus virtually continuous. Depending on the requirements, contact separations from Level Sensors with Reed Switch Chain Technology, Model RMG, Connection Page 1 of 10 Data sheets showing similar products: Level Sensors, magnetostrictive measuring principle; Model FFG; see Data Sheet LM 20.01

2 Further special features Large scope of application due to the simple, proven functional principle For harsh operating conditions, long service life Continuous measurement of the liquid levels irrespective of physical or chemical changes of state of the measured media, such as: foaming, conductivity, dielectric constant, pressure, vacuum, temperature, Signal transmission over large distances - Volume-proportional or depth-proportional of the 3 Level sensors with reed switch chain technology qualify Options - on request) the limit values over the entire measuring range Product prograe Selection of process connection, material and design further information on the indicated pages.
