IS50_IGA50-LOplus_IMPAC pyrometer datasheet

The pyrometers IS 50-LO plus and IGA 50-LO plus are digital, highly accurate pyrometers with fiber op-tics for non-contact temperature measurement on metals, ceramics,graphite etc. between 250° and 2500°C.

The IS 50/67-LO plus is a special version with an extremely short wavelength where molten metal has a very high emissivity.

The instrument type IS 50-Si-LO plus is optimized for measurements on silicon wafers, e.g. in vacuum chambers.

The IS 50-Al-LO plus is specially designed for measurements on alu-minum parts and profiles.

The instrument is equipped with a fibre and an exchangeable optical head. The fiber and optical head are unaffected by electromagnetical in-terferences (e.g. induction) and can be used in high ambient tempera-tures up to 250°C.

Two different types of optical heads for different measuring distances and very small spot sizes are avail-able. A laser targeting light enables the exact alignment onto the meas-uring object.

The very short response time of below 1ms facilitates the measure-ment of fastest heating processes. The pyrometer is equipped with a display which shows in measuring

mode the current temperature. Ad-ditionally all parameters can be read if they are changed via the inte-grated keys at the instrument.Via serial interface and the provided software InfraWin the temperature can be displayed and stored on a PC, parametrizing can also be done.Typical field of application:●Very short response time below 1 ms ●Extremely small spot sizes, min. 0.45 mm ●Built-in LC display ●Laser targeting light

●Parameter adjustments via integrated key pad or interface ●Interface RS232 / RS485 switchable ●Test current output

side the instrument)

Type label Advantages of the digital signal processing: The signal processing of series 50 pyrometers is fully digital, i.e. the detector signal are digitized immediately and digitally processed. With this technique an extremely high accuracy and repeatability is achieved. Accuracy:

The high accuracy is achieved by the digital linearisation of the sensor output as well as the digital compen-sation for the ambient temperature.

Temperature range:Due to the digital technique any temperature sub range within the full temperature range can be set. The ana-log measuring output corresponds automatically to the selected sub range. This setting of a sub range does not effect the high accuracy and repeatability.

Output:The analog measuring outputs 0 - 20 mA or 4 - 20 mA are selectable as well as the serial digital interfaces

RS232 or RS485. Additionally the interface allows the controlling of the pyrometer via PC.

Bus control:The serial interface RS485 facilitates the integration of the pyrometer into existing field bus systems.Calibration: If necessary a calibration of the pyrometers can be done with help of a PC and a calibration source without

opening the housing. Technical Data

Features

Optics

Fiber

The transmission between optical head and converter is done via 0.2 mm mono fiber with a stainless steel protection hose. The opti-cal head contains only the lens, the sensor and the electronics are located in the converter. Fiber and optical head can be used in am-bient tempertures up to 250°C without additional cooling (fibre at converter side max. 125°C). Minimum bending radius:

for short time (max. 250°C):50 mm permanent (max. 250°C):120 mm wound up (max. 50°C):

120 mm

Depending on the application the instrument will be delivered with a small or a large optical head. The selection of the optical head depends not only on its size but also on the required spot size (size of the measuring object) and the measuring distance.

Optical head I :

With the very small dimensions the optical head I is suited for use in confined spaces. The optics is adjusted to one of the measuring distances mentioned in the table. The mentioned spot size will be achieved in exactly this distance (other distances on request).Optical head II :

The optics II is bigger, but smaller spot sizes can be achieved. Two designs are available,fixed adjusted or focusable:

Similar to optics I the fixed adjusted type is adjusted to one of the measuring distances mentioned in the table (other distances on request).

The focusable type is available for 6 different distance ranges. Each measuring distance can be adjusted within the mentioned limits to achieve the smallest spot size in the re-

quired distance.Distance …a “ is specified from the front of the lens
