Accelerate Commissioning & Diagnostics with Veawe’s Precision Analog Signal Simulators

Welcome to Veawe’s Signal Simulator category, your destination for high-accuracy calibration, testing, and troubleshooting tools engineered for automation engineers, system integrators, and maintenance personnel. In control system commissioning and field diagnostics, waiting for actual sensors or dealing with complex wiring to verify PLC/DCS inputs causes unnecessary downtime. Veawe’s portable and benchtop analog signal simulators allow you to accurately generate, simulate, and inject standard process signals on demand.

Whether you need to validate analog input cards, simulate pressure or temperature transmitters, calibrate PID loops, or bench-test control panels, our lineup delivers reliable, stable, and fine-tunable signal generation:

• Current Source Simulators (0/4–20mA): Available with intuitive digital segment displays or compact rotary-dial interfaces, supporting both 24V DC and 230V AC power options for bench or field use.

• Voltage Source Simulators (0–10V / 0–5V): Precision voltage generators designed for rapid testing of analog voltage input channels, VFD reference inputs, and actuator positioning.

• Loop-Powered Simulators: 2-wire and 3-wire loop current simulators designed to mimic 4–20mA transmitters directly across powered measurement loops without requiring an auxiliary power source.

• Dual-Output & Multi-Channel 20mA Simulators: High-density signal sources featuring independently adjustable channels for simultaneous multi-loop verification and calibration.

Key Features of Veawe Analog Simulators:

• Fine-Turn Precision: Smooth multi-turn potentiometers and high-resolution DACs deliver precise output stepping with high accuracy.

• Robust Circuit Protection: Built-in reverse polarity protection, over-current limiting, and output short-circuit protection to withstand accidental field wiring errors.

• Digital Readout Options: Clear 4-digit LED displays providing real-time output feedback in direct engineering units (mA/V).

• Rugged & Compact Form Factor: Durable enclosures designed for both portable toolkits and fixed test-bench setups.
