Continually changing object geometries, different temperatures and very high radiation or surrounding temperatures are no rarity. In a pilger mill those rough conditions can be found, among others in the production of seemless steel pipes. The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C. After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter. Previous solution / Competitor product N/A Solution The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19. The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase. An optimum adaptation to the operating conditions is given due to the adjustable response temperature. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions. The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C. Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling.

Glass Panel Position Measurement using Laser Distance Sensors
In the area of the facility where glass panels are staged, a servodriven actuator system identifies and tracks the leading edge of the glass as it moves along the facility’s conveyor line. After the conveyor apparatus picks up the glass, it is unable to compensate for the non-standard height of the pallets used to transport andstore the glass panels in a horizontal position. Home Case Studies Glass Panel Position Measurement using Laser Distance Sensors Glass Panel Position Measurement using Laser Distance Sensors Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Easy installation thanks to visible laser beam Easy configuration thanks to the free software Operation in the largest temperature range (-40°C to +60°C) possible Measuring ranges up to 100 m on natural surfaces | Measuring ranges up to 500 m on reflective foil Accuracy ± 1mm | Measurements can be acquired by a PLC or PC | Maintenance-free operation Task Leading manufacturers of insulating glass units require a sensor solution that monitors and precisely adjusts glass panel positioning on a production conveyor belt, based on the exact height of non-standard pallets. These pallets are used to transport and store glass panels horizontally. Solution Dimetix Laser Distance Sensors offer several methods of communicating tocontrol systems commonly used in manufacturing and productionapplications. In the area of the facility where glass panels are staged, a servodriven actuator system identifies and tracks the leading edge of the glass as it moves along the facility’s conveyor line. After the conveyor apparatus picks up the glass, it is unable to compensate for the non-standard height of the pallets used to transport andstore the glass panels in a horizontal position. Dimetix Laser Distance Sensor measure the height of the pallet and adjust a position to stop the glass panel. After the panel is halted, the machine begins tilting it onto the pallet precisely at the point where there is no chance the glass can slide or be misplaced. It is then gently placed on the pallets next to other glass panels.

Safety relay monitor can be easily added on. Multiple solutions for wind monitoring are possible. Simple monitoring of the wind speed Basic wind speed monitoring can be achieved by connecting a process Indicator with two 16 bit Analog Inputs to an anemometer with an analog output. Alternatively a digital indicator is required to work with an anemometer with frequency output. Safe operation of the wind speed Better operating safety can be achieved by the parallel operation of two analog or two digital indicators. If a cable break occurs, the second signal path remains intact and continues to reliably monitor the wind speed.
