Industry Pyrometers OKS GE Q

Stationary pyrometers of the OKS GE and OKS Q series measure the temperature of metal objects contactless and provide an analog output signal. Several variants are available for temperature ranges between -75 °C and +2500 °C. The OKS pyrometers have been designed for control and monitoring tasks specifically in the metal industry.

Application areas

  • Temperature measurement of metals

  • Temperature monitoring in presses

  • Process control in furnaces

  • Hardening

  • Preheating

  • Forging

  • Welding

  • Foundries

  • Rolling

  • Annealing

  • Research and Development

  • Steelworks and rolling mills

  • Forging plants

  • Presses

  • Soldering, sintering and hardening

The key feature in selecting a pyrometer is its spectral range. A pyrometer with wavelength as short as possible is recommended, if you want to achieve high accuracy. Through the ratio correction factors it is possible to obtain, with the ratio pyrometers of the OKS Q series, very accurate measurement values regardless of the surface properties of the metal object, or of its emissivity. The pyrometers of the OKS GE series, instead, are ideal for the temperature measurements of metals starting from 75 °C.

Various optical systems ensure best adaptation to the object size. To avoid reading errors, it is necessary to choose a measurement spot that can always be completely filled by the object.

The incorporated LASER light makes precise alignment on the object to be measured easier, as the light dimension approximately represents the measurement spot.

All models are provided with a connector with 0/4-20 mA analog output, and also with a RS-485 interface with galvanic isolation, allowing the parallel operation of up to 32 devices via MODBUS RTU. Through the multilingual Windows software, included in the supply, it is possible to adjust the measurement range and emissivity, as well as to display the temperature values in °C / °F, evaluate and record them. Also max and min. storage value and the measuring rate can be set.

Separate connection cables are available in several lengths. A comprehensive range of accessories allows the adaptation to different operating conditions.

OKSL Q - For measurement of highly fluctuating metal objects

Ratio Pyrometer OKSL Q makes the measurement of highly fluctuating metal objects possible. Thanks to its special optics, accurate measurement is achieved already at 10% coverage of the measuring spot, which makes this model ideal for monitoring and control tasks in foundries or in the wire production. The ration correction provides very high accuracy no matter what the surface properties are, or if the emissivity of the metal objects varies.

The optics and the fibre light cable are suitable for ambient temperature up to 250 °C, which allows measurement quite near the hot material.
