SIGNAL CONDITIONING / MT-AMP-SUM
Combine matched load cells into one weighing signal, with corner trimming for balanced loading. Choose a passive junction box or request an integrated transmitter.

Analog bandwidth and digital sample rate are different quantities. Passive summing boxes do not sample. Named manufacturers are comparison references; electrical, mechanical, software and calibration equivalence requires review.
BRIDGE COMPATIBILITY
Match terminals by function and the sensor datasheet. Wire colors and connector pinouts vary by manufacturer.
A 6-wire connection measures excitation at the bridge through separate sense leads. A 4-wire sensor uses excitation and signal pairs; follow the amplifier manual for local sense links.
Dashed sense lines: 6-wire option. On a 6-wire sensor feeding a 4-wire input, the sensor manual may require sense-to-excitation links of matching polarity. Never infer pin numbers or wire colors.
