Sensors for industrial temperature control

pixels, it offers real-me thermographic images in high speed.

The compact and high-performance infrared camera has a temperature range of -20°C up to 900°C, with an oponal upgrade to 1,500°C. It can be delivered with exchangeable opcs, industrial thermal imager equipment and it comes with an extensive license-free thermography soware package.

Areas of applicaon for the thermal imagers

Optris PI 400

Instrotech, local distributor of process control instrumentaon and specialised systems, has on offer two products specifically for applicaon in the measurement and control of temperature, the Optris CSmicro LT pyrometer, for cement manufacture and Optris PI400 infrared camera.

CEMENT MANUFACTURE and Optris CSmicro

LT pyrometer

Temperature is a crically importance component in the process of making of concrete, and specifically, the importance of controlling the temperature before the concrete is deposited. Opmal temperature of the concrete must fall within the range of +5°C and +55°C, a factor which greatly influences the final characteriscs of concrete and performance (cracking, resistance and wear and tear). Concrete temperature is directly related to the development of strength and fresh concrete can be damaged when exposed to very low or very high temperatures.

Key factors to control during the pouring of concrete related with temperature:

· Warm weather affects speed limits evaporaon

· Cold weather inhibits the hydraon process

Optris' CSmicro LT is equipped with an innovave, miniaturised stainless steel measuring head, the opmally suited for installaon in limited spaces. Its small size and its temperature resistance up to 120°C make the mechanic integraon of the measuring head especially cost-efficient.

The intelligent LED display works oponally as alarm signal, target support, self-diagnosis or temperature-code display. The placement of electronic components within the cable allows for a high temperature resistance of the measuring head. It measures temperature in the range of -40°C to 1,030°C; the spectral range is 8 to 14 µm and the response me is 30 ms - 999 s. The unit can be opmally installed on cement pumps, mixer trucks and cement silos.

Infrared camera Optris PI 400

Optris' PI 400 infrared camera is the smallest thermographic camera in its class. Being equipped with a measurement speed of 80 Hz and an opcal resoluon of 382 x 288

The Optris PI 400 is employed for a variety of tasks in industry. The real-me thermographic images prove especially valuable for surveillance and quality assurance in the , automotivesector plascs, and in the semi-conductor as well as photovoltaic industries.

Due to this type of thermographic cameras' high resoluon and the reacon speed, surveillance and measuring of manufacturing processes that include moving objects poses no problem. Possible areas of applicaon are process automaon of measurement in rotary kilns or measurement of large amounts on conveyor belts during batch processes.

The IR camera also plays an important role in medical diagnosis and prevenon where it detects the slightest of temperature differences. It can even highlight veins under the skin due to its brilliant opcal resoluon of up to 40 mK.

Important Specificaons

· Temperature range: -20°C to 900°C

· Spectral range: 7.5 to 13 µm

· Frame rate: 80 Hz
