- 01 / 07WT4000 industrial weight indicator
One W&M-approved terminal for the apps a process plant actually runs.
The WT4000 is a W&M approved industrial weight indicator built for the chemical, pharmaceutical, food, and general process industries. A 5.7″ color TFT with eight 44-character display lines, a 266 MHz 32-bit ARM running real-time Linux, and a 120,000-record W&M data archive let it stand in for a stack of single-purpose indicators — weigh-and-print, parts counting, vehicle weighing, checkweighing, and filling, all from one terminal.
Modular hardware means the same WT4000 chassis fits a manual workstation, a 2-scale checkweigher, a truck-scale ticket terminal, or an OEM-embedded controller behind a SCADA front-end — without changing the platform underneath.

The WT4000 ships with these application modes installed. Each one is a complete, configurable program — not a feature flag — and you switch between them on the device or by login.
01 BASICBASIC — weigh and print
Capture W&M-approved weight from one or two scales (floor, bench, overhead track). Add IDs via keyboard or barcode (cabled / wireless). Transmit over Ethernet or WLAN. Archive on-device or to host PC.
02 COUNTCOUNT — parts counting
Acquire piece weight from a reference scale. Count in weigh-in or weigh-out mode. Bar-graph display, configurable printout, transmission, article file with item counter and totals memory.
03 TRUCKTRUCK — vehicle weighing
In-and-out vehicle ticketing with stored tare or live tare. ONLINE interface mode for host-system control. Archive of approved tickets stays on the indicator.
04 CHECKCHECK — checkweighing
Static high/low pass-fail. Tolerance bands per product. Visual pass/fail indication. Stats per product, per shift, per operator.
05 DOSDOS NAWI — filling
Filling controller with W&M approval. Single- or two-speed dosing, automatic preact compensation, tolerance check, and product file. Suits chemical, food, and pharma fills.
06 CONTROLCONTROL / ONLINE
Setpoint controller and PC-driven ONLINE interface. Drop the WT4000 in behind a PLC or SCADA layer when the host controls sequencing and the indicator handles W&M-approved weight capture.
03 / 07Where the WT4000 fitsIndustries the platform was built around.
01Chemical & pharmaceutical
Recipe-driven filling and batching with on-device data archive that meets W&M approval requirements for legal-for-trade documentation.
Recipe + archive02Food & beverage
Bench and floor weighing, checkweighing, mobile data capture, and recipe filling — with stainless housing, IP-rated entries, and wash-down tolerance.
Stainless + washdown03Truck & vehicle scales
In/out ticketing terminal with on-device archive of W&M-approved tickets. ONLINE mode for SCADA-fronted yards.
In / out / ONLINE04Mobile data capture
WLAN + barcode + on-device archive turns the WT4000 into a portable inventory and receiving terminal at the dock door or in the warehouse.
WLAN + barcode04 / 07Architecture & integrationWhat's actually inside.
266 MHz 32-bit ARM processor running a Linux real-time multitasking OS with an integrated web server. 0.5 MB data memory with power-fail-safe data storage. Selectable update rate of 50–800 Hz on analog strain-gauge inputs — high enough for fast dosing, slow enough for stable static weighing.
The indicator is W&M-approved for legal-for-trade weighing. Its 120,000-record on-device archive holds W&M-approved weighings without depending on a PC being online — useful when the network drops or audit pulls a sample from last quarter.

Do I need WT4000, WT6000, or WT8000?
Roughly: WT4000 is the workhorse mid-size industrial indicator with the standard application set. WT6000 adds freer programmability and heavier I/O for batching and demanding industrial loops. WT8000 is the IP69K stainless controller with the deepest I/O for filling, batching, checkweighing, and vehicle weighing. Send us your application and we’ll narrow it down.
Is the WT4000 W&M approved out of the box?
Yes — the WT4000 is W&M approved (legal-for-trade) and carries NTEP approval as an indicating element. The 120,000-record archive stores approved weighings on-device.
Can I write my own application?
The WT4000 ships configurable, not freely programmable. For custom-coded application logic, the WT6000 is the freely-programmable terminal in the same family.
How many load cells does the input support?
The analog strain-gauge input (entry impedance 43 Ω to 3.3 kΩ) is suited to eight 350 Ω load cells, or to four 350 Ω load cells through zener barriers. Digital force transducers can be connected as an option. Send us your load cell model and cell count and we’ll confirm fit.
Can the WT4000 talk to my PLC / SCADA / ERP?
Yes. Use Ethernet and the integrated web server for HTTP-style integrations; ONLINE mode for PC-driven sequencing; barcode for ID capture. For Modbus and fieldbus protocols, send us the host system spec and we’ll confirm the right interface module.
Stainless steel housing — what's the wash-down rating?
The WT4000 stainless steel desk or wall housing is rated IP65 / IP69K, NEMA 4X. The panel-mount version has a fascia plate protected to IP69K, NEMA 4X. Tell us your washdown conditions and we will confirm the right version.
