EGT (pyrometer) amplifier · Type K thermocouple · 0 – 5 V analog out
The output side is the same three wires as any pressure sensor — supply, ground, signal — so it wires into any analog input and calibrates with two points. Sold as the module alone: the probe and the bung it threads into are bought separately, to the specifications under Recommended to use with.
| Parameter | EG5 | EG12 |
|---|---|---|
| Sensor | Type K thermocouple, ungrounded | Type K thermocouple, ungrounded |
| Range | 0 – 960 °C | 0 – 1250 °C |
| Output | 5 mV/°C | 4 mV/°C |
| Zero | 0.000 V = 0 °C | 0.000 V = 0 °C |
| Supply | 5 V — the ECU's sensor rail | 8 – 16 V switched, 12 V nominal |
| Input protection | Direct input | Series limits, RC filter and clamp diodes on both legs |
| Initial accuracy | ±3 °C at 25 °C | ±3 °C at 60 °C |
| Size | 36.3 × 27.5 × 15.6 mm, 51.1 mm long over the zip-tie saddles, ASA-CF | 44 × 34 × 16.1 mm, 58.8 mm long over the zip-tie saddles, ASA-CF |
| Connectors | Thermocouple cable: a miniature Type K socket. Output cable: none. Every ECU takes its inputs in its own plug, so one fitted here would most often be cut off; the cable comes stripped, ready for your ECU's terminal or a splice. Orders of 10 or more can have a connector fitted to your pinout, quoted on request | Thermocouple cable: a miniature Type K socket. Output cable: none.

Output cable: red supply · black ground · yellow signal, stripped back 13 mm, the tips bare. Thermocouple cable: yellow + · red −, ending in a miniature Type K socket.
Setup guides: wiring and software setup for Speeduino, MegaSquirt, Haltech, Link, AEM, Holley EFI, MaxxECU and more.
The module is sold alone. Buy the probe, its fitting and any extension wire to these specifications.
