Application information

Z4A force transducer:
Precision force transducers of the Z4A type series measure tensile forces and
compressive forces.
They measure static and quasi-static forces with great accuracy and
reproducibility and therefore require judicious handling. You must take
particular care when transporting and installing the devices. If you knock or
drop the transducers, this could permanently damage them.
Z4A force transducer with DKD certificate from HBM:
Force transducer calibrated with guaranteed class 00 (20kN − 200kN) and 0.5
(500kN) according to DIN EN10002-3 or ISO / FDIS 376.
The transducers are calibrated as standard in the tensile force direction. On
request, however, they can also be calibrated in the compressive force
direction, under the DKD.
The limits for the permissible mechanical, thermal and electrical stresses are
stated in the Specifications. Be sure to allow for them when planning the
measuring setup, when installing and lastly, when operating.

Structure and mode of operation

11.1 Measuring body

The measuring body comprises a system of measuring springs with 8 applied
strain gauges (S.G.). The strain gauges are arranged so that four of them are
extended and the other four are upset when a force acts on the transducer.
For the introduction of tensile forces, the Z4A transducer has a crowned
threaded pin at the top (also suitable for the introduction of compressive
forces) and a tapped hole at the bottom.
