Device Labels

On the top of the pyrometer there is the label (nameplate) as well as a warning sticker for IR sensors with a

laser targeting light.

▪ Mount the device in a manner that the labels are still clearly visible after installation.
▪ Keep the warning signs in legible condition
▪ Replace damaged labels
2.6

Identification Label

The identification label on top of the device shows information to:
▪ Distributor logo
▪ Series / order number (for breakdown see chap. 9.2)
▪ Temperature range, serial number, serial interface(s), analog output and
power supply
▪ CE sign and crossed-out waste container product mark (see
▪ Manufacturing company.
2.7 Laser Targeting Light
For easy alignment, the pyrometers may be equipped with a laser target-
ing light, laser class 2 (according to IEC 60825-1). The laser emits a visi-
ble red light with a power of <1 mW and a wavelength around 650 nm.
SAFETY INSTRUCTIONS
▪ Never look into the direct or reflected laser beam.
▪ Do not point the laser to anyone.
▪ If laser radiation hits the eye, avert one's eyes immediately.
2.8

Through-lens Sighting

Devices with through-lens sighting and temperature range above 1400°C are equipped with an adjustable eye
protection filter in the eyepiece to reduce glare at high measurement temperatures. The unprotected look at
temperatures >1400°C can damage eye function permanently.
SAFETY INSTRUCTIONS
▪ Only look with darkened eyepiece at objects with temperatures above 1400°C / 2552°F to protect the eyes
against glare at high radiation temperatures.
▪ Before looking at the high temperatures, always first adjust the eyepiece by turning it to the darkest position.
