Level relay-sensors ROS 101 (ROS 102) of the capacitive type are designed to monitor the level of electrically conductive and non—electrically conductive liquids, solid (bulk, including powdery) media, as well as the separation of media (water — light petroleum products, liquefied petroleum gases – water) and other liquids with sharply different permittivity.
Level relay-sensors ROS 101 (ROS 102) are used in automated process control systems, in alarm systems of technological and emergency levels.
Relay-sensors meet the requirements of the Rules of the Russian Maritime Register of Shipping and the Russian River Register for signaling devices, measurement and control of non-electrical quantities for vessels with an unrestricted area of navigation. Relay-sensors have versions designed for the use at nuclear energy facilities (hereinafter referred to as NF), including at nuclear power plants (NPP).
Depending on the PT design, the method for attaching, the operating temperature range, the maximum operating pressure, the length of the submerged part of the SE, the relay sensors have the versions presented in table:
