Westach EGT and CHT Gauges

Westach has been supplying reliable, high-quality gauges for aircraft since 1944. EGT gauges are an excellent way to monitor engine health and air/fuel mixture. Low readings usually indicate a rich mixture, while high readings typically indicate a lean mixture.

Westach self-powered (Type J) thermocouples and gauges make perfect sense for formula cars and sports racers with total-loss electrical systems. The difference in temperature between the thermocouple tip and the opposite end of the thermocouple cable generates a small electrical current, which moves the gauge needle. They require no connection to vehicle power, and no batteries.

We offer Westach single and dual Exhaust Gas Temperature (EGT) gauges and single Cylinder Head Temperature (CHT) gauges in the standard 2 1/16 inch diameter. A selector switch is also available to read up to four probes on one gauge (or one side of a dual gauge).

FF1600 Kent and F2000/S2000 Pinto engines with a single Weber DGV carburetor can typically use only two probes to monitor jetting. Cylinders # 1 and 4 are most sensitive to changes in jetting on the primary throat, while # 2 and 3 reflect changes in jetting on the secondary throat.
