3.11 Connecting the Bridge Head
(For Strain Module)
Connect a strain gauge bridge (bridge head) or strain gauge transducer and measure the strain.
This section describes the procedures for connecting YOKOGAWA's bridge head (700932/
700933) and precautions regarding the connection. For details on connecting other strain gauge
bridges and strain gauge transducers, see the corresponding manuals.
CAUTION
Do not connect any other devices other than strain gauge bridge and strain gauge
transducer to the strain module. Connecting other devices or applying voltages
exceeding the value shown below can damage the input section.
Maximum input voltage (across terminals)
5 V (DC+ACpeak)
Maximum allowable common mode voltage (across each terminal and earth)
42 V (DC+ACpeak) (CAT I and II, 30 Vrms)
Connecting the Strain Gauge
Bridge head 700932/700933 supports six types of connecting methods: single-gauge method,
single-gauge three-wire method, adjacent-side two-gauge method, opposed-side two-gauge
method, opposed-side two-gauge three-wire method, and four-gauge method. For details, see
the manual, IM700932-01E that came with bridge head 700932/700933. If you are using a
strain gauge bridge other than 700932/700933 or a strain gauge transducer, then see the
corresponding manuals.
Connecting the Strain Module and the Bridge Head
When using bridge head 700932/700933
Connect the strain module and the bridge head using the cable that is included with 700932/
700933.
