2.2 Product specific safety recommendations
These safety recommendations are based on a risk analysis carried out in
accordance with the requirements of the machinery and low voltage di-
rective in order to comply with European standards for CE marking.
2.2.1
General
The possibility of risk from a consistency transmitter in operation only
arises when covers have been removed during installation and servicing,
due to hazardous electrical voltage.
Read these safety recommendations before installing the transmitter.
Follow the recommendations when installing the transmitter, starting up
and servicing. Use warning signs for safety information!
These safety recommendations apply to the transmitter fitted with an AC
powered electronics box. Mounting parts, such as the weld-in studs, are
dealt with in accordance with the pressure vessel standards of the respec-
tive countries.
!
For good personal and functional safety: Use only parts which
have been manufactured or approved by BTG.
2.2.2
Selecting a transmitter model and assembly
parts
Pressurized parts must be suited to the current maximum pipe pressure in
relation to temperature. Select a material for the parts that are in contact
with the medium so that corrosion does not occur.
2.2.3
Installing mounting details
Welding and subsequent inspection should take place in accordance with
current standards and regulations.
2.2.4
Installing the transmitter
•
Construct a platform or use safe and approved ladders if the
transmitter is located high up. This platform will make it easier to fit
and start-up the transmitter and carry out service in the future.
•
The rubber quality of the transmitter seal (O-ring) should be selected
to suit the current medium. The O-ring supplied is suitable for this
application.
•
Screw the valve assembly firmly onto the weld-in stud.
Be sure that the pipe is
empty before opening it!
