KDEV-N Summary of advantages and characteristics of torque sensor series products

1, the core technology advantages

A. High-precision measurement

Nonlinear error: generally ≤0.5%F.S (for example, KDEV-N-5A reaches 0.1%F.S), and the highest repeatability is 0.03% f.s (KDEV-N-50a).

Temperature stability: the sensitivity temperature drift is 0.03% ~ 0.1%/10℃ (such as KDEV-N-11A), and the compensation range covers -40~160℃ (high temperature model).

Long-term stability: one million cycle life (for example, KDEV-N-5C is nominally one million cycles), and excellent creep resistance (0.05% f.s/30min).

B. Diversified transmission and installation

Wireless transmission: KDEV-N-4A/43A and other models adopt electromagnetic coupling technology, which supports RS485/ analog signal/pulse signal output and is maintenance-free.

Flange/keyway double installation: support shaft connection, flange connection, disc installation (such as KDEV-N-5G), suitable for various mechanical structures.

High-speed adaptation: Some models support high-speed operation at 1800rpm(KDEV-N-11A) or 8000rpm(KDEV-N-4A).

C. Material and structural reliability

Corrosion-resistant design: stainless steel, alloy steel and aviation aluminum are the main materials, and the surface is anodized or sealed and welded (such as KDEV-N-5C protection grade IP66).

Low deformation design: aviation aluminum shell+high strength shaft core (such as 17-4 stainless steel), with deformation ≤0.05%F.S(KDEV-N-43A).

Miniaturized package: the minimum diameter is only φ 3mm (KDEV-N-50) and the height is as low as 7.2mm(KDEV-N-50A), which is suitable for narrow space.

D. Environmental adaptability

Wide temperature range: -40~160℃ ultra-wide temperature range (such as KDEV-N-43A), supporting extreme industrial scenes.

Explosion-proof and protection: IP65~IP67 protection level, supporting damp, dust and oily environment (such as KDEV-N-50 protection level IP65).

2, typical model features

Industry and automobile field (KDEV-N-11A/4A series)

Super load capacity: the measuring range covers 0.05 nm ~ 5,000 nm (such as KDEV-N-5000), which is specially used for testing motors, engines and gearboxes.

High stability output: the output sensitivity is adjustable from 1.0 to 2.0 mv/v, and the zero output error is 1% to 2% f.s.

Customized design: support flange specification customization (such as M6~M20 thread) and optional aviation plug (6~10 pins).

New energy and precision manufacturing (KDEV-N-F series)

High-temperature waterproof performance: KDEV-N-F05 supports 150℃ high temperature +IP67 waterproof, and directly hits the pain points of lithium battery coating, photovoltaic welding machine and other scenes.

Ultra-thin and high sensitivity: the thickness of KDEV-N-F05 is only 1.2mm, and the sensitivity reaches 2.0 10% MV/V, which is suitable for thin film pressure detection.

High dynamic response: KDEV-N-F0A series sampling rate is 1000Hz, and real-time feedback of force control signals (such as robot polishing and precision assembly).

Medical and Laboratory (KDEV-N-50 Series)

Low deformation and high cleanliness: 316L stainless steel, with polished surface, meeting the hygienic standard of medical equipment.

Micro-force detection: the measuring range is as low as 0.05Nm(KDEV-N-50) and the resolution is 0.03%F.S, which is suitable for cell mechanics test and tactile feedback of surgical robots.

Semiconductors and 3C Electronics (KDEV-N-C Series)

Anti-static and anti-interference: insulation resistance ≥ 5000 mω, shielding design to reduce electromagnetic interference (such as wafer handling and chip packaging).

High-precision calibration: nonlinear ≤0.1%F.S (such as KDEV-N-5C), meeting the requirements of semiconductor precision assembly.

3, industry application advantages

Intelligent manufacturing: automobile stamping, robot grasping, AGV logistics weighing.

New energy: monitoring the electrode pressure of lithium battery, and detecting the welding force of photovoltaic module.
