7MH5113-5JD00

What is this load cell used for?

It is designed for industrial weighing applications where force/weight needs to be measured accurately, such as hopper, tank, silo, platform or process weighing systems.

What is the rated capacity?

The rated load is 28 tonnes (28 t). For selection, the total system capacity should account for the number of load cells, vessel self-weight, product weight and any dynamic loads.

What accuracy class does it meet?

It is classified as C3 in accordance with OIML R60, which is a commonly specified accuracy class for trade-oriented and high-accuracy industrial weighing designs.

Is it suitable for wet or harsh environments?

Yes. The enclosure is rated to IP68, indicating strong protection against dust ingress and long-term immersion conditions as defined by the manufacturer’s rating.

What material is the load cell made from?

The load cell body is made of stainless steel, which is typically chosen for corrosion resistance in industrial environments.

What cable is supplied and how long is it?

It is supplied with a 15 metre integral cable, which can help when routing to a junction box or weighing instrument without needing an extension.

How many wires does the cable have?

It uses a 4-wire connection. In many weighing systems this corresponds to the excitation and signal pairs; confirm terminal naming on the connected instrument or junction box before wiring.

Can it be used in multi-load-cell systems (for example, under a vessel)?

Yes. It is commonly used in multi-cell arrangements; the overall system performance depends on mechanical installation, load distribution, summing/junction method and instrument configuration.

Does it work with standard industrial weighing electronics?

It is intended for use with compatible strain-gauge load cell weighing instruments that accept 4-wire load cell connections and support OIML-class installations where required.

What does IP68 mean in practical terms for installation planning?

IP68 indicates a high level of ingress protection. For installation planning, also consider cable routing, glands/junction box sealing, and avoiding water traps that can stress the cable entry over time.

How should I choose the number of load cells for a vessel or structure?

The number is typically driven by the mechanical design (support points), stability, and how the load is introduced. Ensure the rated capacity per support point is not exceeded when considering uneven loading and dynamic effects.

Is it appropriate for use where official verification requirements apply?

The C3 classification to OIML R60 is often specified for systems that may be submitted for verification, but the overall compliance depends on the complete weighing system design, installation and local regulatory requirements.

What should I consider regarding overload or shock loads?

Allow margin for non-ideal conditions such as impact, vibration, start/stop forces, product surges and uneven loading. Designing in headroom beyond the rated load per cell helps reduce the risk of mechanical overload.

Does this item have any typical identification that can be referenced when specifying it?

It is commonly specified as a Siwarex WL 280 load cell with RN-S SA 28 t, C3, stainless steel construction, IP68 rating, and a 15 m 4-wire cable (often referenced as 7MH5113-5JD00 in specifications).
