Product Specifications

Technical details and manufacturing context for Load Cell Scale

Definition

The load cell scale is a component used in automated beverage ingredient dispensing systems to measure the weight of liquid or powdered ingredients. It converts the mechanical force exerted by the ingredient mass into electrical signals via strain gauge technology, enabling precise portion control according to recipe specifications. This component is critical for maintaining consistency, reducing waste, and ensuring product quality in beverage production.

The scale typically consists of a stainless steel or aluminum alloy housing, strain gauge sensors, and signal conditioning circuitry. It is designed for washdown environments, with an ingress protection rating of IP67 and a 304 stainless steel material option for corrosion resistance. The scale's capacity ranges from 0 to 50 kg, with an accuracy of ±0.05 g (per OIML R76). Response time is ≤100 ms, and it operates within a temperature range of -10°C to 50°C. The output signal is a 4-20 mA analog current loop, with a rated output of 2.0 ±0.2 mV/V. Excitation voltage should be 9-36 V DC, and input/output resistance is 350 ±5 Ω. Insulation resistance is ≥5000 MΩ at 50 V DC. Safe overload is 150% of full scale, and ultimate overload is 300%.

When selecting a load cell scale, verify that the capacity, accuracy, and environmental ratings match the specific application. Confirm the output signal compatibility with the dispensing system's controller. Check the excitation voltage and resistance values against the system's electrical specifications. Ensure the ingress protection and material grade are suitable for the cleaning and operating conditions. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The load cell scale operates on the principle of strain gauge technology. When beverage ingredients are placed on the weighing platform, the applied force causes deformation in the load cell's sensing element. This deformation changes the electrical resistance of strain gauges bonded to the cell, producing a proportional voltage output that is converted to a digital weight reading by the system's controller.
