Intelligent Power-Analysis Sensor
The core of every Celijia system. A sensor-free weighing technology that derives lifting load directly from the hoisting motor's current and voltage signals — no mechanical strain element, no calibration drift, no field-exposed hardware.
Request data sheetOverview
The Intelligent Power-Analysis Sensor is Celijia's flagship technology. Instead of measuring force with a mechanical strain element, it acquires the hoisting-motor's current and voltage signals through high-precision current and voltage transformers and calculates motor torque output. Combined with the mechanical transmission ratio, the result is the actual lifting load — in real time, with no mechanical sensor in the load path.
Because the sensing element is purely electrical and is mounted inside the equipment room, it is immune to the field-exposure failures that plague traditional load-pin and shear-beam sensors: zero drift, water ingress, mechanical fatigue and impact damage. Customers routinely run the system for five years without calibration and report a service life beyond twelve years.
Every higher-level Celijia product — overload protection, dual weighing, anti-mislifting, advanced load identification, remote diagnostics — is built on top of this sensor. Twenty years of motor power-signal R&D, originator of the category since 2011, with more than 2,000 cranes equipped and 140+ terminal customers behind it.
