Electrical connection

Amplifiers designed for strain gage systems can be used for measurement
signal conditioning. Carrier frequency can also be connected to DC amplifiers.
If you have to check testing machines in accordance with EN 12390, connect
each of the four measuring bridges to a check of an amplifier system.
If you would like to use the KDB to determine total force, connect all the
measuring bridges in parallel.
The KDB force transducer is delivered with six-wire configuration and is
available with the following electrical connections:
S Bayonet connector: plug-compatible with the MIL-C-26482 series 1
connection (PT02E10-6P); IP67
8.1

Connection in a six-wire configuration

With this cable assignment, the output voltage at the measuring amplifier is
positive in the tensile direction when the transducer is loaded.
The cable shield is connected with the transducer housing. This produces a
Faraday cage which covers the sensor, the cable and – provided it is correctly
wired – the plug to the amplifier, thus ensuring optimum safety, even in the
critical EMC environment.
Only use plugs that meet EMC guidelines. The shielding must be connected
extensively. With other connection techniques, an EMC-proof shield should be
applied in the stranded wire area and this shielding should also be connected
extensively (also see HBM Greenline Information).

Cable shortening or extension

We cannot recommend the extension of the connection cable. HBM offers
cables in various lengths (including mounted plug for sensor and amplifier). For
precise results we recommend calibrating with the cables that will actually be
used for the application.
