Strain gage full or half bridge and piezo-resistive sensors in 4-wire configuration with
Zero-Wire TEDS, version for D-sub-HD15
Important: The solder terminals on the TEDS module are marked AMP
(Amplifier) and TD (Transducer) together with the numbers. On the TD side,
you have to connect contact 2 with 2' and 3 with 3' (short circuit or feedback
bridges), otherwise the measured value is always invalid.
Abb. 20: Plug terminal X4, pin assignment in 4-wire configuration and with Zero-Wire
TEDS, version for D-sub-HD15; with half bridge, connector 4 is omitted
