Maintenance
The force transducers in the F5301 model series are maintenance-
free.
During welding work the transducer must be bypassed with a copper
wire (min. 50 mm 2 ) so that welding current does not flow through the
transducer and weld the force introduction points.

Ambient temperature
The temperature range of -20°C to +80°C that is specified in the data
sheet applies with regard to deployment. The specified error limits are
not guaranteed outside this temperature range.
Moisture and corrosion protection
Tropical climates and condensation are not a problem because the
transducers comply with protection class IP 67 in accordance with
EN 60529:1991+A1:2000 / IEC 529.
Deposits
Dust, dirt and other object must not be allowed to form deposits in
such a way that they create a force short-circuit to the measuring
spring, which would falsify the measuring signal.
Precautions to take during assembly
• Force measuring equipment is extremely sensitive and must be
handled carefully.
• Attention must be paid to the installation position and therefore the
load direction when the force transducers are being installed.
• The transverse loads and side forces also include the relevant
components of the measured variables, which may be introduced at
an incline.
• Care must therefore be taken to keep the transducer free of lateral
loads and torsion during assembly (e.g. when tightening the lock
nuts).
• Overloading must be prevented at all times.
• The output signal (c=1-2mV/V, 4...20mA, 0…20mA, 0...10V) is noted
on the name plate (Fig. 1). The connection assignments are also
noted on the name plate and can also be found in the section entitled
“Electrical connection”. The polarity must be correct at all times.
