3 Overview
3.1 Appropriate
use
The pyrometer IS 50-LO/GL is specially designed for the glass industry. It is used for the temperature measurement of
glass in tank, working end, forehearth and feeder. Additional applications are the measurement of brickworks in regen-
erator and tank.
Using a robust fibre optic cable (length up to 30 m) enables the use of the instrument in an ambient temperature up to
250°C without cooling.
3.2
Scope of delivery
Converter, optical head, fibre (5 m) with stainless steel protective coating, work certificate, user manual.
optional lengths up to 30 m, in increments of 2.5 m
Note:
A connection cable is not included with the instrument and has to be ordered separately
(see section
Reference numbers
).
4 Safety
This section offers an overview about important safety aspects.
Additionally in the several sections there are concrete safety aspects to avert danger. These aspects are indicated with
symbols. Labels and markings at the instrument have to be noticed and keep in a permanent readable condition.
4.1 General
Each person working with the pyrometer must have read and understood the user manual before operation. Also this has
to be done if the person already used similar instruments or was already trained by the manufacturer.
The pyrometer has only to be used for the purpose described in the manual. It is recommended to use only accessories
offered by the manufacturer.
4.2 Electrical
connection
Follow common safety regulations for mains voltage (e.g. 230 or 115 V AC) connecting additional devices operating with
this mains voltage (e.g. transformers). Touching mains voltage can be mortal. A non expert connection and mounting can
cause serious health or material damages.
Only qualified specialists are allowed to connect such devices to the mains voltage.
4.3 Ambient
temperature
The pyrometers are designed for ambient temperatures of 0 ... 70°C with non-condensing conditions. The optical head
can be used in ambient temperatures up to 250°C without cooling, the fibre at the end of the optical head up to 250°C, at
the end of the pyrometer up to 125°C. An operation under other conditions can damage or malfunction the instrument.
