3.2 Mechanical Installation
For mounting the pyrometer is equipped with a mounting rail on the bottom. This rail allows
easy fixing of an adjustable mounting angle or a ball and socket mounting. Another possibility
for fixing the pyrometer is using the 4 thread holes M 5 on the front of the instrument.
3.3 Sighting
For exact aiming to the object the pyrometers are equipped with a thru-lens view finder, a laser
targeting light or a color camera module.
3.3.1 Thru-lens view finder
The view finder can be used to align the measured object
through direct observation. The view finder is true-sided
and parallax-free; a circle marks the position of the
measuring area, but not the exact size.
The pyrometers are equipped with an adjustable eye
protection filter. Turning the ocular changes the filter from
bright to dark.
3.3.2 Laser targeting light
The laser targeting light is a red laser beam used to align
the pyrometer at a target. The laser marks the center of
the measuring spot. The laser targeting light can be used
during operation without effecting the measurement.
When the laser targeting light is
switched on, the green control light
on the rear cover is blinking and the
display shows “PILT”.
The laser targeting light can be switched on and off either by pressing the button at the
housing or by using an external contact connecting pins H and K or connecting an external
voltage (5 to 30 V DC) to pin H or via PC and
InfraWin
software (see
3.1.1 Pin assignment of
the male socket on the back of the pyrometer
). After two minutes the laser targeting light
is switched off automatically.
Note:
To prevent damage to the laser, the laser targeting light switches off
automatically if the internal temperature of the device goes above approx. 55 °C (then
it can not be switched on again until the temperature is lower again)!
3.3.3 Color camera module
The color camera module enables the optical alignment of the
pyrometer to the measuring object via video screen or
monitor.
The video output of the pyrometer will be connected directly
to the video input of a monitor or a TV card. A target circle on
the monitor allows the exact alignment to the measuring
object. The target circle marks the place of the measuring spot
but not its exact size.
The window displays the preset emissivity and the current measuring temperature. Additionally
the date, time and a text can be displayed if activated via the software
InfraWin
.
