Challenges Replacement of existing mechanical cam limit switches limiting the end position of movable plant components on a large conveyor bridge in open-pit mining. This is intended to eliminate the following problems: Inaccurate switching points due to backlash and hysteresis High maintenance, installation and start-up times with standstill and disruption to the value creation chain Mandatory inspections require a lot of time and effort High costs for backup devices and maintenance Lack of approval for safety functions in line with current standards and directives After: Electronic position switch ERC 40 replaces mechanical cam limit switches.

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. Customer Benefits Maintenance-free High temperature stability Recognition of hot objects at big distances Self adjustment with Auto-Teach or step switch for the response temperature Product Part number OKA 2038.38 G Brand Proxitron Accessories Piros swivel stand HM2 Tube OL 19 Pilot light unit (for alignment) DAK 308 + OL 26 Different cable lengths (e.g. 15 m) Customer Testimonial compared to previous solution or competition Case Studies Other Solutions in Mining & Material Handling Sample case study title lorem ipsum here Short description of the problem solved, maybe include the client name.
