The picture shows a hot-rolled vertical roll mill for steel sections in a steel plant (steel rolling equipment). The KTR3P spring self-resetting electronic ruler is installed on the side pressure cylinder of the vertical roll (AWC width adjustment cylinder)

Function: Real-time detection of the lateral downward stroke of the rolls, used to control the finished width of the rolled steel plates/sections (AWC automatic width control system for rolling mills)

Working conditions: The equipment is full of oil stains and the cooling water is rusted. This is a typical working condition in a hot rolling workshop. The KTR3P spring self-tightening structure is suitable for this environment.


The KTR series built-in spring self-resetting displacement sensor (also known as: electronic ruler, resistance ruler, potentiometer, displacement sensor, crack displacement detector) principle: The principle of potentiometer: All sensors are position measurement type, used in regulation systems (control systems) and measurement systems to directly measure displacement and length, and output DC voltage signals. The signals can also be converted into standard 0-5V, 0-10V or 4-20mA DC signals through built-in or external V/A transmission modules. It can also transmit control requirements over long distances. The KTR series built-in spring self-resetting displacement sensor (also known as: electronic ruler, resistance ruler, potentiometer, displacement sensor) outputs displacement variation: 0-100% given input working voltage (varying with displacement).
