FNIRSI SG-004A Multifunction Signal Generator & Calibrator – 0-24mA 0-24V PWM RTD Thermocouple Simulator in Pakistan

Overview

The FNIRSI SG-004A is a high-precision, multifunction process calibrator. It is designed for engineers who need to do more than just simple loop testing. With its ability to simulate and measure Thermocouples (8 types) and RTDs (Pt100/Cu50), it is the go-to tool for thermal processing, chemical plants, and advanced automation labs. The large colour screen even provides a Real-time Trend Curve, allowing you to monitor signal stability over time.

Key Features

• Source & Measure Simultaneously: The screen is split into two halves—top for output (Source) and bottom for input (Measure).

• Massive Signal Support: Handles DC Voltage, DC Current, Frequency, Pulse, PWM, Resistance, plus various Thermocouples and RTDs.

• Real-time Graphing: Automatically converts signals into a trend curve, making it easy to spot jitters or drifts in a system.

• Programmable Output: Set up “Auto-Step” or “Slope” outputs to test how a valve or motor reacts to a gradual increase in signal.

• Engineering Unit Conversion: Don’t do math in your head! Convert $4-20\text{mA}$ signals directly into $0-100\%$ or any custom scale.

• USB-C Interface: Fast charging and firmware updates to keep your tool current with the latest industrial standards.
