Challenges
Temperature of the furnace / crucible needed to be measured
Solution
- Portable Option and Fixed Type Options
- In order to accurate measure the temperature of the crucible, a portable / hand-help thermometer optris P20 05M or fixed infrared thermometer optris CTlaser 05M can be used. With a temperature range between 1,000°C and 2,000°C and spectral range of 525 nm both are ideally suited for molten metal applications
- Upto to 2,000 measured values can be saved on the portable device and a USB port can be used to transfer data to a computer.
- Analog output signal of 4-20mA.
- 4-6 m sensing distance
- 60-80° angle
- Peak hold function to see value on display

Challenge
- The increasing flexibility of production lines requires a high adaptability of sensors. 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.

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
