Moisture and corrosion protection
Tropical climates and condensation are not a problem because the load
pins 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. The design of the accessory cable also com-
plies with protection class IP 67. The IP67 protection is guaranteed only
when connected.
5.3
Deposits
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.

Precautions to take during assembly
• Force measuring equipment is extremely sensitive and must be han-
• Attention must be paid to the installation position and therefore the
dled carefully.
• Torsional moments, transverse or centric loads and side forces cause
load direction when the load pins are being installed.
• Care must therefore be taken to keep the load pin free of lateral loads
measurement errors and can damage the load pin permantly.
• Overloading must be prevented at all times.
and torsion during assembly
• The output signal is noted on the name plate (Fig. 1 to 4, p. 33-34).
• The connection assignments are also noted on the name plate
(Fig. 1 to 4, p. 33-34) and can also be found in the section entitled
"Electrical connection". The polarity must be correct at all times.
