Description

Performance, precision and reliability – you can count on MAURER pyrometers. Benefit from maximum adaptability by choosing the right optics, accessories and the appropriate interface. Thus our pyrometer fits perfectly into existing systems.

The most important features and characteristics at a glance:

Spectral range: 1,4 – 1,75 μm and 1,6 – 1,75 μm
Short response time from less than 1 ms
Emissivity slope from 0,8 – 1,2, adjustable directly at the pyrometer or via interface
Green target light (LED) that is exactly identical to the actual measuring spot in position and size
With fiber optic cable and optic system for exact focusing even in narrow spaces
Use with either digital and analogue output
1 limit output (open collector)
Operating voltage 24 V DC
Free software (IR-LOG) for parameter setting, data recording and storage

Scope of Applications
Processing of steel, iron, non-ferrous metal and wires, as well as rolling, soldering, annealing, hardening, forging, transforming, induction heating, etc.

Fiber optic cables

Quartz fiber optic cable in metal hose
Ambient temperature max. 150 °C
Minimum bending radius = 200 x fiber thickness
Both sides with FSMA-plug for connecting the pyrometer and the optic system
Custom-tailored lengths and other fibers available upon request.
