Signal Conditioning PCB for Voltmeters and Ammeters

Product Specifications

Technical details and manufacturing context for Signal Conditioning PCB

Definition

This signal conditioning PCB is a specialized printed circuit board that functions as the signal processing core within measurement circuits for voltmeters and ammeters. It conditions raw electrical signals from sensors by performing amplification, filtering, isolation, and linearization to ensure accurate, stable, and noise-free measurements suitable for display or further processing. The board accepts input signals in the range of 0–10 V, typical of standard sensor outputs, and provides an output signal range of 0–10 V, compatible with analog-to-digital converter (ADC) inputs. Gain accuracy is ±0.1%, and nonlinearity is ±0.05%, ensuring measurement fidelity and a linear response. The bandwidth covers 0–100 kHz, accommodating typical sensor frequencies. Input impedance is at least 1 MΩ to minimize loading on the sensor, while output impedance is 50 Ω or less to drive cables and loads effectively. The board operates from a 24 V DC supply (with ±10% tolerance) and is rated for an operating temperature range of -40 to 85 °C, suitable for industrial environments. Storage temperature range is -55 to 125 °C, and non-condensing humidity tolerance is 5–95% RH. The ingress protection rating is IP54–IP65 per IEC 60529, providing dust and water resistance. The board material is FR-4 epoxy laminate, flame retardant and standard grade per IPC-4101. Dimensions are 100 mm × 80 mm, offering a compact footprint for enclosures. The PCB includes copper traces, solder mask, and electronic components such as ICs, resistors, capacitors, and connectors. This product is a component intended for integration into measurement systems; verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The signal conditioning PCB receives low-level, noisy, or non-linear electrical signals from measurement sensors such as voltage dividers or shunt resistors. Its integrated circuits and components amplify weak signals, filter out high-frequency noise and interference, provide electrical isolation to protect measurement instruments, and linearize sensor outputs. The result is a clean, standardized signal proportional to the measured physical quantity (voltage or current), suitable for accurate display or further processing by voltmeters and ammeters.
