Industrial Force Measurement

High-Resolution Load Cells for Gantry Crane Safety

Absolute calibration curves verified under Indian industrial metrology standards for overload protection and process weighing.

Key Specifications

Strain gauge load cells, load pins, and dynamic force sensors with 0.02% accuracy, IP67 protection, and 10-point calibration certificates traceable to Indian metrology standards.

Why choose Fdym

Measurable advantages for crane safety

Every benefit is backed by Indian metrology standards and field-proven hardware.
01

Absolute calibration curves

Each load cell and pin ships with a 10-point certificate traceable to Indian industrial metrology. No guesswork during commissioning.

Eliminates field re-calibration delays.
02

Retrofit without structural changes

LP-200 load pins replace existing clevis pins directly. The strain gauge bridge is fully integrated, so you keep the original mechanical assembly.

Reduces downtime to a single shift.
03

High-resolution overload detection

HR-500 load cells resolve force changes as small as 0.02 % of rated capacity. Overload thresholds trigger before the crane reaches 105 % load.

Prevents structural fatigue and regulatory fines.
04

Dynamic event capture at 10 kHz

DFS-100 sensors record transient forces during lifting, braking, and wind gusts. The 20 kHz natural frequency ensures no aliasing in your PLC.

Enables predictive maintenance on hoist components.
05

IP67 sealed for outdoor yards

Hermetically sealed stainless steel bodies resist dust, rain, and washdown. Rated for continuous operation from –20 °C to 70 °C.

Survives monsoon seasons without drift.
06

Compatible with existing PLCs

All sensors output standard mV/V or 4–20 mA signals. No proprietary controllers needed – connect directly to your crane’s safety relay or display.

Works with Siemens, Allen-Bradley, and Mitsubishi systems.
Package A

Single Load Cell Kit

One HR-500 high-resolution strain gauge load cell (0.02% accuracy, IP67) with a 10-point calibration certificate, 5 m shielded cable, and a quick-start guide for PLC integration. Suitable for single-point weighing on small to medium gantry cranes.

Package B

Dual Load Pin Set

Two LP-200 series load pins (5–500 t each) with integrated full-bridge strain gauges, replacement clevis pins, and a junction box for summing outputs. Includes a 10-point calibration certificate for each pin. Designed for retrofit on existing crane sheave assemblies.

Package C

Dynamic Force Sensor Bundle

One DFS-100 piezoelectric sensor (10 kHz bandwidth, 20 kHz natural frequency) with built-in charge amplifier, M12 mounting adapter, and a 5-point dynamic calibration certificate. Ideal for impact testing and transient force monitoring during crane start-up or emergency stops.

Package D

Complete Overload Protection System

Four HR-500 load cells, two LP-200 load pins, one DFS-100 sensor, a multi-channel display unit, and a relay output module for alarm/stop signals. Each sensor comes with its own 10-point calibration certificate. Includes on-site commissioning support and a one-year warranty.

All packages are supplied with individual calibration curves traceable to Indian metrology standards. Contact us for custom configurations and OEM integration support.

Why engineers trust Fdym for overload protection

Our force sensors are built for the specific demands of gantry crane safety — not repurposed from lab equipment. Every unit ships with an absolute calibration curve verified under Indian industrial metrology standards.

We do not sell generic load cells. Each sensor is individually characterised from zero to rated capacity, and the curve is printed on the certificate. No interpolation, no guesswork.
Metrology-grade calibration

Every load cell and load pin is calibrated on a deadweight force standard machine traceable to NABL. The 10-point certificate includes both ascending and descending readings, so you know the hysteresis and repeatability before installation.

Designed for retrofit, not redesign

Our LP-200 load pins drop directly into existing clevis mounts. No welding, no structural modification. The integrated strain gauge bridge outputs a standard mV/V signal that connects to any PLC or display unit already on site.

Rated for Indian industrial conditions

Ambient temperatures up to 70°C, dust, humidity, and voltage fluctuations are the norm in Indian ports and steel plants. Our sensors are sealed to IP67, with stainless steel bodies and PTFE-jacketed cables rated for continuous flexing.

Dynamic response for real loads

Gantry cranes experience shock loads during lifting and lowering. Our DFS-100 dynamic sensor captures transients at 10 kHz, while the HR-500 load cell settles within 50 ms. You get accurate peak readings, not averaged noise.

Local support, not a distant helpline

Our team is based in Model Town, Delhi. We answer calls in Indian time zones, and we can visit your site for commissioning or troubleshooting. No waiting for a callback from a different continent.

Absolute curves, not relative offsets

Many load cells ship with a generic sensitivity value. Ours include a printed curve showing output at every 10% step from zero to full scale. You can verify the reading at any point without external reference weights.
