Description

The SOPMH-103 utilizes a bonded strain gauge Wheatstone bridge configuration to convert applied mechanical force into a proportional electrical signal. Its 1.4mV/V sensitivity provides a strong, measurable output when excited with a standard 5-15V DC supply, ensuring reliable performance when paired with instrumentation amplifiers and data acquisition systems.

Engineered for stability, the sensor features a high 2000MΩ insulation resistance and controlled output impedance (350Ω) to minimize signal drift and electrical interference in industrial settings. The robust mechanical design and specified -20°C to +60°C operating range ensure consistent, repeatable measurements in demanding automation, process control, and testing environments.

Frequently Asked Questions

What is the required excitation voltage for this load cell?

The SOPMH-103 load cell requires a DC excitation voltage between 5V and 15V. A stable, regulated power supply within this range is recommended to ensure accurate output signal generation and maintain the specified 1.4mV/V sensitivity.

How do I connect this load cell to a microcontroller like an Arduino?

This load cell outputs a small differential millivolt signal (1.4mV/V). You cannot connect it directly to an Arduino. You must use a dedicated load cell amplifier or HX711 breakout board. The amplifier will provide the required excitation voltage, amplify the signal, and convert it to a digital format readable by the microcontroller.

Can this sensor be used for both pushing (compression) and pulling (tension) forces?

Yes, the SOPMH-103 is designed for dual-mode operation and is suitable for both compression and tension force measurements. Ensure the mechanical mounting fixtures apply force strictly along the sensor's central axis to prevent side loads that can cause measurement errors or damage.

What is the meaning of '0.3% F.S' accuracy?

"0.3% F.S" (Full Scale) accuracy means the maximum potential error of the sensor's reading is 0.3% of its 50kg rated capacity. For this load cell, the maximum error across its entire range is ±0.15kg (50kg * 0.003). This includes combined effects of nonlinearity, hysteresis, and repeatability.

What are the physical dimensions and mounting considerations?

The sensor has an outer diameter of 27mm and a length of 40mm, weighing 55g. It typically requires mounting via threaded holes on its end faces. Proper installation is critical: the mounting surfaces must be parallel, rigid, and ensure force is applied axially to achieve rated performance and longevity.
