The WeightechUSA WT4 (SKU 40001) sums up to four analog load cells into one signal for the weight indicator, with an individual trimpot per cell for corner adjustment. Cast-aluminum housing, PA66 cable glands and IP68 sealing make it suitable for indoor and outdoor scales.
The datasheet lists automation systems, platform scales, and silos or reactors in industrial yards, including outdoors. As a general-purpose 4-cell junction box it is also used on:
Groups the load cells of a scale section and trims corners to match.
Compact sealed box for platforms and chutes exposed to washdown and dust.
Four-corner platforms where each corner must read the same weight.
Multi-cell vessel weighing in industrial yards, indoors or outdoors.
Cast aluminum with a high degree of thermal and electrical insulation, in a compact 135 × 65 × 38 mm footprint.
Polyamide PA66 glands accept cables from 3.5 to 7 mm outer diameter, with excellent sealing and high mechanical resistance.
Sealing finish rated IP68: the box can be exposed to high-pressure jets and dust.
Inside, the adjustment board carries four groups of five terminals (CN1–CN4), one per load cell, each paired with its own trimpot (T1–T4). The adjustment range is approximately 4.2% of output for 350 Ω load cells.
Remove jumpers J1, J2, J3 and J4 — always all four together.
New boxes ship centered. Otherwise turn each trimpot to the end of its range (sequential click), then 10 turns back.
To lower a corner reading, turn VR1 (T1) and VR2 (T2) clockwise, VR3 (T3) and VR4 (T4) counterclockwise.
Zero the indicator, load each corner and compare diagonally (cell 1 vs 3, 2 vs 4). Trim the higher corner down to match; repeat until equal.
