About - Mini Digital Pyrometer Gauge "Superlite-A" with 0–5 VDC Analog Output
Why Add a 0–5 VDC Retransmission Output to a Pyrometer Gauge
The PMD2XT-A adds a 0 to 5 VDC analog retransmission output to the standard PMD1XT platform. This output is derived from the gauge’s retransmission signal using the included resistor, allowing the unit to drive both a display and a voltage signal simultaneously.
Without an analog output, the gauge functions purely as a display device — information reaches the driver but cannot be shared with other systems. With the 0–5 V output, the gauge simultaneously drives the LED display and retransmits a proportional voltage to any downstream device that accepts voltage input: a data logger, an ECU analog input, a standalone alarm module, or a second display at a different location in the vehicle.
The retransmission output mirrors the live temperature reading, not the peak hold value, meaning the data logger captures real-time EGT rather than a static peak. For applications where post-session analysis of temperature versus throttle position, gear position, or other logged channels is required, this live output is essential. The PMD1XT without analog output cannot serve as a source node in a data acquisition chain — the PMD2XT-A can.
How the 0–5 V Output Maps to Temperature
The 0 to 5 VDC output is scaled across the display range configured in the gauge. For example, with a Type K thermocouple configured for a 0°F to 2300°F range, 0 V corresponds to 0°F and 5 V corresponds to 2300°F — a span of 460°F per volt.
The measurement resolution is based on the internal 16-bit A/D converter, while the analog output provides sufficient resolution for typical temperature logging applications. The data logger must be configured with the same scaling formula to convert the incoming voltage back into a meaningful temperature value during post-processing.
Integration with Data Loggers and ECUs
Most racing data loggers and ECUs accept 0–5 VDC analog inputs as a standard signal type. The PMD2XT-A analog output can be connected directly to these inputs without additional signal conditioning, making integration straightforward.
For EFI ECUs that can act on EGT data — such as triggering a protection strategy when exhaust temperature exceeds a threshold — the 0–5 V output provides a usable input signal that can be scaled and processed directly.
This allows a single PMD2XT-A to serve multiple roles simultaneously: driver display, data logger input, and ECU monitoring or protection signal. Contact The Sensor Connection for assistance configuring scaling parameters for specific systems.
