ELECTRICAL CONNECTION

The following can be connected for measurement signal conditioning:
S
Carrier-frequency amplifiers
S
DC voltage amplifiers
that are designed for strain gage measurement systems.
The load cells are available in a four-wire and six-wire configuration or are equipped with
a connector plug. The pin assignment is specified in the following section or in the
relevant data sheet for the load cell available at www.hbm.com/pw.
5.1

Connection in four-wire and six-wire configurations

When load cells calibrated with a six-wire configuration are connected to amplifiers with
a four-wire configuration, the sense leads of the load cells must be connected to the
corresponding supply leads.
When load cells calibrated with a four-wire configuration are connected to amplifiers with
a six-wire connection, a relevant bridge must be attached to the amplifier input between
the sense lead and supply lead.
