Frequently asked questions
Answers to the most common questions about our products and services
Z7A offers 0.5, 1, 2, 5 and 10 t maximum capacities. Check threads, dimensions, deflection and permissible side loads for the particular capacity.
No. The D1 table covers 0.5–10 t, while C3 lists 2, 5 and 10 t. D1 and C3 correspond to 1000 and 3000 verification intervals respectively, not sampling rates.
The datasheet specifies six-wire connection and 2 mV/V nominal sensitivity. Use a suitable excited strain-gauge bridge input and preserve the cell data in system calibration.
No. Ingress protection is IP67, but the measuring body is specified as galvanized steel. Cable-gland material is specified separately. Do not infer body material from IP rating.
Yes. The higher parenthesized side-load values require stops preventing cell-base movement, and the manufacturer warns of significant error effects under that condition. ZEL and ZPL supports are listed as separately ordered accessories.
