Moisture and corrosion protection
5.2
Tropical climates and condensation are not a problem because the
tension links comply with protection class IP 67 in accordance to
EN 60529:1991+A1:2000 / IEC 529. The entire measuring spring is
made of stainless steel or fine-grained steel with surface protection.
The design of the accessory cable also complies with protection class
IP 67. The IP 67 protection is guaranteed only when connected.
Deposits
5.3
Dust, dirt and other objects are not allowed to form deposits in such a
way that they create a force shunt to the measuring spring, which
would falsify the measuring signal.

Mechanical installation conditions of tension links
Precautions to take during assembly
6.1
•
Force measuring equipment is extremely sensitive and must be han-
dled carefully.
•
Attention must be paid to the installation position and therefore the
load direction when the tension links are being installed.
•
Torsional moments, transverse or centric loads and side forces cause
measurement errors and can damage the tension link permanently.
•
Care must therefore be taken to keep the tension link free of lateral
loads and torsion during assembly
•
Overloading must be prevented at all times.
•
The output signal is noted on the name plate (Fig. 1 to 3, p. 27-28).
•
The connection assignments are also noted on the name plate (Fig. 1
to 3, p. 29-30) and can also be found in the section entitled “Electrical
connection”. The polarity must be correct at all times.
