- 01 / 06WeightechUSA WTX-4 junction box
IP68 stainless-steel junction box for 2 to 4 load cells.
The WeightechUSA WTX-4 (SKU 40021) combines the signal of two to four load cells for the weight indicator, with an individual trimpot per cell for corner adjustment. The stainless-steel enclosure is sealed to IP68 for outdoor use, and a GORE valve pressure equalizer adds protection against internal condensation.

The datasheet names automation systems, platform scales, and silos or reactors in industrial yards. As a general-purpose 4-cell junction box it is also used on:
01Platform and floor scales
Four-corner platforms where each corner must read the same weight.
02Silos, tanks and reactors
Multi-cell vessel weighing in industrial yards, indoors or outdoors.
03Truck and vehicle scales
Groups the load cells of a scale section and trims corners to match.
04Livestock and cattle chute scales
Sealed stainless box for platforms and chutes exposed to washdown and dust.
03 / 06ConstructionWhat the box is built from.
01Stainless-steel enclosure
Encapsulated in stainless steel and perfectly sealed for outdoor use, rated IP68.
02GORE pressure-equalizer valve
The GORE valve gives additional protection against internal condensation.
03PA66 cable glands
Polyamide PA66 glands accept cables from 3.5 to 7 mm outer diameter, with excellent sealing and high mechanical resistance.
04 / 06Corner adjustmentOne trimpot per load cell.
The corner-adjustment board sits inside the box. Each load cell connects to a group of five terminals (CN1–CN4), and each group is tied to its own trimpot (T1–T4). The adjustment range is approximately 4.2% of output for 350 Ω load cells.
STEP 1Open the jumpers
Remove jumpers J1, J2, J3 and J4 — always all four together.
STEP 2Center the trimpots
New boxes ship centered. Otherwise turn each trimpot to the end of its range (sequential click), then 10 turns back.
STEP 3Know the direction
To lower a corner reading, turn VR1 (T1) and VR2 (T2) clockwise, VR3 (T3) and VR4 (T4) counterclockwise.
STEP 4Compare and trim
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.
