Level relay-sensors ROS 301 of the conductometric principle of operation provide reliable control from one to three levels of electrically conductive liquid in one or more containers, including in explosive zones.

 

Level relay-sensors ROS 301 are installed in automatic process control systems, in alarm systems of limit and emergency liquid levels in tanks for various purposes, in automation and control devices.

 

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 design of the sensing element, the insulator material, the maximum operating pressure, the operating temperature range and method for attaching, the relay sensors have the versions presented in table:
