APPLICATION NOTES
4 APPLICATION NOTES
Force transducer Z30A
Series Z30A precision force transducers measure tensile and compressive forces.
They measure static and quasi‐static forces with great accuracy and reproducibility and
therefore require judicious handling. You must be particularly vigilant when transporting
and installing the devices. If the transducers are dropped or jolted, permanent damage
could be caused.
Z30A force transducers complete with DKD certificate from HBM
Force transducer calibrated to guaranteed class 00 according to ISO 376.
As standard these transducers are calibrated in the tensile direction. On request they can
also be calibrated in the compressive direction to DKD standards.
The limits for permissible mechanical, thermal and electrical stresses are stated in the
specifications. Be sure to allow for them when planning, installing and operating the
measurement configuration .

Z30A
STRUCTURE AND MODE OF OPERATION
8
5 STRUCTURE AND MODE OF OPERATION
5.1 Measuring body
The measuring body comprises a system of measuring body with strain gages (double
bending beam principle).
5.2 Housing
The enclosure provides protection against splashes and minor impacts (IP50 degree or
protection per DIN EN60529).
5.3 Disturbance variables
Torsion, bending and transverse loads are disturbance variables and are therefore to be
avoided. If necessary they can be remedied with HBM mounting accessories (see
chapter 7.3 ).

Z30A
CONDITIONS ON SITE
6 CONDITIONS ON SITE
6.1 Ambient temperature
The effects of temperature on the zero signal and on the sensitivity are compensated. To
achieve optimal measurement results the nominal temperature range must be
maintained. Temperature‐induced measurement errors can be caused by uneven cooling
or heating (for example by radiant heat). A radiation shield and all‐round heat insulation
bring about marked improvements. They must not form a force shunt.
6.2 Moisture
Extreme humidity or a tropical climate should be avoided if this means that the classified
limit values are exceeded (degree of protection IP50 under DIN EN 60529).
6.3 Air pressure
Changes in air pressure have no effect on the force transducer since it is not hermetically
sealed.
6.4 Chemical effects
The aluminium enclosure of the transducer is protected by a powder coating. If used in
difficult environmental conditions (direct weather effects, contact with media which
encourage corrosion) additional protective measures should be employed by the user.

MECHANICAL INSTALLATION

7 MECHANICAL INSTALLATION
7.1 Important precautions during installation
Streat the transducer gently
Sif measuring compressive forces, make sure there is a solid support structure
Sthe force‐introduction surfaces must be scrupulously clean and fully load‐bearing
Skeep to the depths of engagement for threaded rods or knuckle eyes
Sdo not overload the transducer.
WARNING
If there is a risk of breakage through overload on the transducer and thus a risk to persons,
additional safety measures are to be taken.
7.2 General installation guidelines
The measurement direction in which forces act on the transducer must be as precise as
possible.
WARNING
Torsion and bending moments, eccentric loading and transverse forces result in measure
ment errors and if limit values are exceeded, could destroy the transducer.
7.3 Mounting accessories for tensile/compressive loading
Knuckle eyes are available for installing with the Z30A (see page 24). These mounting
accessories prevent the introduction of torsional moments into the transducer. Using two
knuckle eyes will also exclude bending moments, shear loading and eccentric loading.
Knuckle eyes are mainly provided to deal with static tensile loading on the transducer.
For dynamic loading, Z30A transducers must be installed free from play. Knuckle eyes
have only limited application in the case of dynamic loading, since alternating dynamic
stress increases the play in the universal joints and falsifies the measured value. It also
produces a self‐amplifying load cycle which can destroy the knuckle eyes. The breaking
force is only 150% Fnom.
Thrust pieces EDO3/1kN or EDO4/50kN (see page 26) and two load buttons (see page
25) are available for introducing compressive forces.

Notes on mounting with knuckle eyes
1. Shaft diameter
When using a sensor with knuckle eyes mounted on one or both sides, make sure that the
shaft is the right size.
You will find the diameters of the knuckle eyes, suitable shafts and their recommended
tolerances in the table below

CAUTION
If a shaft with an overly small diameter is used, the bearing of the knuckle eye will be
subjected to linear load. This subjects the inner bearing shell to excessive load, which can
lead to damage and, if forces are high, can cause the knuckle eye bearing to break.
Select the shaft as recommended in the mounting instructions.
2. Distance between knuckle eye and shaft bearing
The shaft support must allow for suitable play between the knuckle eye and the shaft
bearing.
CAUTION
If there is too much distance between the knuckle eye and the shaft bearing, this generates
bending moments in the shaft, causing it to deform.
This deformation puts strain on points of the edges of the inner bearing shell, which can
cause the knuckle eye or shaft to suffer damage or break.
Select the play as recommended in the mounting instructions.
To determine the play between the knuckle eye and the shaft bearing, you can apply the
following rule of thumb:
Shaft diameter Play between knuckle eye and bearing
<30 mm 1/10 of the nominal diameter
Tab. 7.2 Rule of thumb for determining play between knuckle eye and shaft bearing
Based on this, recommendations for the play between the knuckle eye and shaft bearing
are as follows:
Knuckle eye Play between knuckle eye and shaft bearing
1-U1R/200kg/ZGW 0.8mm
1-U2a/1t/ZGUW 1.2mm

ELECTRICAL CONNECTION
8 ELECTRICAL CONNECTION
8.1 Instructions for cabling
SAlways use shielded, low‐capacity measurement cable (HBM cables meet these
requirements).
SDo not lay measurement cable parallel to high‐voltage power lines or control circuits.
If this is not possible (e.g. in cable ducts) protect the measurement cable, e.g. with
armoured steel tube and maintain a minimum distance of 50 cm from the other
cables. High‐voltage power lines and control lines should be twisted (15 turns per
meter).
SAvoid stray fields of transformers, motors and contactors.
SDo not earth transducer, amplifier and display device more than once. All the devices
in the measurement chain are to be connected to the same earthed conductor.
SThe screen of the connection cable is connected to the transducer housing.
8.2 Pin assignment
Two 7‐pin male device connectors are located on the enclosure (male connectors, Series
723). To avoid creating force bypasses through the cable, you can use either the lower or
the lateral connector, depending on the configuration.
If the transducer is connected according to the following connection diagram then when
the transducer has compressive loading the output voltage at the measuring amplifier is
positive.

8.3 TEDS transducer identification
TEDS stands for ”Transducer Electronic Data Sheet”.
An electronic data sheet is stored in the transducer as defined in the IEEE 1451.4
standard, making it possible for the measuring amplifier to be set up automatically. A
suitably equipped amplifier imports the transducer characteristics (electronic data
sheet), translates them into its own settings and measurement can start.
At connection PIN 7 (to ground at PIN 2), there is a digital identification system available.
The basis for this is a 1‐wire EEPROM DS2433, from Maxim/Dallas.
HBM provides you with the TEDS Editor for storing your data. This is included in the
software for the MGCplus Setup Assistant (see TEDS operating manual “TEDS-module in
transducer” on our website at ww.hbm.com/TEDS).
The Editor also makes it possible to manage the different user rights, to protect the
fundamental transducer data from being inadvertently overwritten.
