Description
BLH Nobel KIS-2 20 kN | Industrial Weigh Module
Product Introduction
When replacing a load cell in a production weighing system, matching the rated capacity is only the first step. The BLH Nobel KIS-2 20 kN is a weigh module from the KIS-2 family, which combines a load cell with mounting hardware for industrial process-weight and force measurement. BLH Nobel describes the KIS-2 as a double-cantilever design with a floating load point, intended to reduce sensitivity to lateral forces and accommodate demanding process conditions.
The 20 kN capacity is part of the manufacturer’s documented KIS-2 range. The official datasheet lists a 2.040 mV/V rated output, ±0.05% rated-output combined error, 0.01% repeatability, stainless-steel load-cell construction, and IP67 protection. These are model-family specifications—not proof that a specific used unit retains its original calibration or includes every mounting component.
For maintenance teams, the practical replacement checks are the complete mounting arrangement, load direction, cable version, excitation compatibility, and the condition of the sensing element. A KIS-2 20 kN module should not be substituted based on capacity alone.

Global Sourcing & Live-Test SOP
For a used or surplus BLH Nobel 20 kN, inspection should cover both the load cell and the mechanical weigh-module assembly. A sensor can look intact while carrying overload damage, calibration drift, or mounting problems.
1. Inbound Verification
- Photograph the complete nameplate, model, rated capacity, and serial number.
- Confirm the series and 20 kN rating.
- Record any additional ordering code or configuration marking.
- Photograph the load cell, mounting brackets, yoke, tilt guard, and all included hardware.
- Verify whether the item is a complete weigh module or a load-cell-only assembly.
- Inspect the cable and strain relief for cuts, crushing, or previous repairs.
- Retain available OEM documentation and calibration records.
2. Mechanical Inspection
- Inspect the load cell body for deformation, impact marks, corrosion, or evidence of overload.
- Check mounting surfaces and fastener holes for wear or damage.
- Confirm the load point and mounting hardware move or seat as intended by the OEM design.
- Inspect the yoke, bracket, and tilt guard for missing or modified components.
- Verify that the intended installation applies load through the specified load path.
- Do not drill, machine, or modify the load cell or mounting hardware to force fitment.
3. Electrical Inspection and Signal Test
Testing should be performed with suitable load-cell instrumentation and a controlled test setup.
- Verify excitation and signal wiring against the applicable BLH Nobel documentation.
- Measure input and output resistance and compare against OEM limits.
- Check cable shielding and insulation condition.
- Apply the recommended excitation voltage.
- Record the no-load output and check for abnormal drift or instability.
- Apply a controlled load and confirm a stable, repeatable signal response.
- Avoid applying unverified overloads or using improvised fixtures.
4. Calibration and Load Validation
A continuity check or measurable output does not establish accuracy.
- Use a traceable load or force reference suitable for the 20 kN capacity.
- Verify zero balance and output stability.
- Apply controlled loads across the intended operating range.
- Check repeatability and hysteresis using an appropriate calibration procedure.
- Confirm compatibility with the receiving weighing transmitter or signal conditioner.
- Record the calibration results and any limitations.
5. Extended Test and Final Documentation
Where suitable test equipment is available, conduct an application-appropriate stability test.
Record:
- Test date and duration
- Model, serial number, and rated capacity
- Excitation voltage
- Input/output resistance measurements
- No-load output
- Applied test loads
- Calibration or repeatability results
- Cable and mounting condition
- Any observed drift or abnormal behavior
Protect the load cell and mounting hardware from impact during shipment. Use suitable packaging and clearly distinguish visual inspection from electrical testing and documented calibration.
Field Engineer’s Pitfall Guide
❗ 1. A 20 kN rating does not guarantee mechanical interchangeability
The family includes multiple capacities and mounting configurations. Confirm the dimensional drawing, load direction, mounting footprint, and included hardware before substituting it into an existing vessel or process-weighing installation. BLH Nobel provides CAD resources for checking physical fit.
❗ 2. Do not confuse the complete weigh module with a bare load cell
BLH Nobel identifies as a weigh module with built-in mounting hardware. However, surplus listings may show incomplete assemblies or load-cell-only units. Verify the brackets, yoke, tilt guard, and other required components in the actual offer.
❗ 3. A signal test is not a calibration certificate
A load cell may produce a plausible millivolt signal and still have accuracy, repeatability, or creep problems. For regulated, quality-critical, or batch-accountability applications, require appropriate calibration evidence before returning the sensor to service.
Intent-Driven FAQ
What is the BLH Nobel 20 kN?
It is a 20 kN-rated load-cell weigh module in BLH Nobel’s family. The family is designed for industrial process weighing, batching, vessel weighing, and tension-measurement applications.
Is the 20 kN a complete weigh module?
is documented by BLH Nobel as a weigh module with built-in mounting hardware. Still, confirm whether the specific seller’s unit includes all mounting components, since used listings may be incomplete.
What is the rated output of the 20 kN?
The BLH Nobel datasheet lists a rated output of 2.040 mV/V for the family. Actual signal output depends on excitation voltage and applied load.
What excitation voltage does the require?
The datasheet recommends 10 VDC or VAC excitation and lists 18 VDC or VAC as the maximum. Follow the applicable transmitter and OEM requirements when commissioning the sensor.
Is the 20 kN suitable for tank or vessel weighing?
The family is intended for process weighing and batching applications, including vessel-related installations. Suitability for a particular tank depends on load distribution, mounting geometry, number of sensors, and the complete weighing-system design.
Can I replace another 20 kN load cell with the ?
Not based on capacity alone. Confirm mechanical dimensions, load direction, rated output, bridge resistance, cable configuration, mounting hardware, and transmitter compatibility.
What should I verify before buying a used 20 kN?
Request clear photos of the nameplate, sensor body, cable, and mounting assembly. Confirm rated capacity, serial number, completeness, physical condition, calibration history, and test status. Do not assume a warranty or calibration certificate is included unless the seller explicitly documents it.
Bottom Line for Buyers
The BLH Nobel 20 kN is an industrial weigh module designed for process weighing and force measurement. Its double-cantilever construction, floating load point, and documented 2.040 mV/V output make it a configuration-specific replacement component—not a generic 20 kN sensor.
For procurement, match the full model and capacity, verify the mounting assembly and cable, and request available calibration or test records. A complete, correctly configured module with documented condition is a more dependable replacement candidate than a unit identified by capacity alone.
