48452BA2 Rev.06, 04/2023
3Product Description
The GAMMAcast detectors convert the Gamma-rays emitted by a source of radia-
tion into electrical impulses. The pulse rate emitted at the output of the GAM-
MAcast detectors to the evaluation unit is proportional to the impinging radiation
intensity.
The GAMMAcast detectors described herein are scintillation counters that, in con-
nection with a suitable evaluation unit, determine the radiation intensity occurring
during a radiometric measurement.

The GAMMAcast detectors consist of the following components:
•Stainless steel housing
•Electronics with integrated CPU
•Scintillator (crystal - LB 6739 / LB 6760 or PVT - LB 6752)
•Water cooling system (optional for LB 6739 / LB 6760)

3.1.1 Scintillator
The GAMMAcast detectors are distinguished by means of the external dimensions
and the scintillators used.
•GAMMAcast detector LB 6739:
Scintillation counter with crystal and photomultiplier (see technical infor-
mation, chapter 1)
•GAMMAcast detector LB 6752:
Polymer scintillation counter with photomultiplier (see technical information,
chapter 1)
•GAMMAcast detector LB 6760:
Scintillation counter with crystal and silicon photomultiplier (see technical in-
formation, chapter 2)
3.1.2 Connection Cable
The plug-in connection "PlugProtect" protects the transition between the GAM-
MAcast detector and the connection cable against moisture penetration. The heat
protection hose covering the connection cable protects it against too high temper-
atures.
The connection cables are commonly connected to a terminal box. For this purpose,
a variant with HeavyCon plug or open ends can be used. The terminal box is con-
nected to the EVU.
3.1.3 Water Cooling System
A version of the GAMMAcast detectors with water cooling is available to protect
the scintillators against too high temperatures. The GAMMAcast detector LB 6752
has already been provided with a water cooling system integrated into the hous-
ing.
Storage
Keep devices in a dry (no condensation), dark (no direct sunlight), clean and lock-
able room. Stay within the temperature range for storage (see document “Tech-
nical Information”).

Initial Operation
DANGER
Danger to life from electric shock!
Installation may only be carried out by a qualified electrician.
Installation may only be carried out if all components has been de-ener-
gised.
Only open the housings when there is no voltage.
NOTICE
Danger due to inadmissible place of use!
The GAMMAcast detectors must not be used in systems in which explosive
gases or vapours may form. They are not explosion-proof.
NOTICE
Risk of breaking!
The GAMMAcast detector contains a PMT with glass housing and/or a fragile
scintillation crystal. The glass housing of the PMT can break. The crystal can
break or splinter.
Handle the GAMMAcast detector with care.
Mount the GAMMAcast detector to the outside or inside of the mould. If required,
connect the water cooling system. Additional information is provided in chap. 4.3.
The GAMMAcast detector is connected either via a terminal box (Fig.3) or directly
to the EVU. The connection diagram of the respective evaluation unit is to be taken
into account. For the connection to the EVU, please also refer to the connection
diagram provided in the operating manual of the EVU.

Terminal Box
The detectors and the EVU are to be connected via the terminal box. This connec-
tion is to be made with a standard 6–wire shielded cable (6 x 0.5 mm²) with a max-
imum length of up to 1000 m. As required, the terminal box can be ordered for
open ends (Mat. No. 07005, Fig.2, item 1) or with an industrial connector (Mat.
No. 34787, Fig.2, item 2).

4.2.1 Mounting the Terminal Box
Fig.3 Mounting the terminal box (variant with industrial connector)
Install the terminal box near the mould in a protected but easily accessible place.
The terminal box can be installed in different ways and manners depending on:
•the general physical conditions at the site.
•the temperature conditions around the casting floor.
•the distance from the mold.
The terminal box must be secured to a wall or to a pillar so that the sturdy cable
(connection lines inside the hose) will not move the terminal box.

Insert the GAMMAcast detector with water cooling system into the bore in the
mould that corresponds to the GAMMAcast detector. When using a water cooling
system (with GAMMAcast detector LB 6739 or LB 6760), please note that the bore
must be accordingly bigger.
When fixing the GAMMAcast detector to the water cooling system, please make
sure that the discharge nozzle on the mould is at the highest point (Fig.5, item 3
and Fig.6, item 4.) This will ensure that there is always enough water in the water
cooling system and that no air bubbles can form.
NOTICE
Damage to the device!
When using water that does not have the same quality as drinking water, the
water cooling system and the GAMMAcast detector may be damaged due to
deposits of dirt particles.
Reduced cooling power!
Only water that has the same purity as drinking water may be used as coolant.
Please observe the minimum cooling water requirement of the GAMMAcast
detectors (chap. 4.4).
Connect the inlet and outlet of the cooling water to the GAMMAcast detector
(LB 6739 / LB 6760: Fig.5, item 1 and 3; LB 6752: Fig.6, item 3 and 4).
