vektsensor

A vektsensor, or weight sensor, is a device that measures the force exerted by a load under gravity and converts it into an electrical signal. It is a core component of weighing systems used in laboratories, manufacturing, logistics, and consumer scales. In many applications the term denotes the transducer element, typically a load cell, rather than the complete instrument.

Most vektsensor devices rely on a transduction principle that converts mechanical deformation into an electrical quantity. The most common type is a strain-gauge load cell, where metal foils bonded to a deforming element change resistance as the member bends under load. Other technologies include capacitive, piezoelectric, hydraulic or pneumatic, and optical sensors.

Applications include retail and industrial scales, process weighing, tank and hopper measurement, dynamometry, and laboratory balances. They are used where accurate and repeatable weight measurement is required and may be deployed in standalone devices or integrated into automation systems.

Performance characteristics include accuracy (nonlinearity, hysteresis, and repeatability), sensitivity, temperature effects, and overload protection. Calibration is performed with known reference weights, typically including tare and span adjustments. Environmental considerations such as vibration, shock, moisture, and dust influence performance and may require protective enclosures (IP ratings).

Electrical output is commonly analog (0–10 V or 4–20 mA) or digital (RS-232/RS-485, I2C, SPI, CAN). Signal conditioning and data processing normalize the signal for display or control systems. Standards and calibration traceability are maintained through organizations such as OIML and national metrology institutes, enabling consistent performance across instruments and regions.
