Alcor temperature probes and instruments was founded in 1957 by Al and Alice Hundere in San Antonio, TX. Over the next 50 years Alcor and the Hundere family would design, develop, and manufacture exhaust gas temperature (EGT), cylinder head temperature (CHT) and turbine inlet temperature (TIT) probes, along with instrumentation to read them.
About Alcor Temperature Probes and Instruments
As a pioneer in the EGT method of mixture control, Alcor patented the durable thermocouple in 1965; a key component of the EGT system. Al Hundere’s innovation continues to be used by pilots all over the world as the EGT method to control and monitor their engines fuel-air ratio.
Today Alcor is an affiliate of Tempest Aero Group® and stands alone as the world leader in EGT, CHT and TIT thermocouples. Preferred by the most well-known original equipment manufacturers (OEMS) of both aircraft and engine monitors, Alcor’s reputation for innovation and high-quality products is unmatched. Alcor temperature probes are compatible with most engine monitors, from the classic analog instrumentation to the most current glass panel systems. The blanket Supplemental Type Certificate (STC) held by Alcor allows for the installation of probes in any aircraft with a reciprocating engine.
Whether you’re an owner looking to upgrade thermocouples for your engine monitoring system or an OEM needing a clean sheet design Alcor can help. Our probes are manufactured using only top-grade materials which allow us to have the smallest element tips for the fastest response time.
The Products of Alcor Temperature Probes and Instruments
Probes
A thermocouple (also called a sensor or probe) is a device formed by the junction between two dissimilar metals, which transforms heat energy into electrical energy. Aviation Exhaust Gas Temperature (EGT)/Turbine Inlet Temperature (TIT) and Cylinder Head Temperature (CHT) systems use thermocouples, lead wires composed of the same two dissimilar metals, and an indicator. Below is an example of an Exhaust Gas Temperature (EGT) thermocouple.
Instruments
Instruments are meters used to monitor the EGT, TIT, or CHT of an internal combustion engine when coupled with a thermocouple. Pilots can increase the life of their engines and enhance safety through the proper monitoring of EGT and CHT.
Alcor instruments are designed to provide temperature compensation for accurate readings year-round, on the ground and at altitude. They are intended for use on single and twin-engine aircraft and calibrated to true temperature. There’s no risk of malfunction during electrical failure as they require no external source of power for operation.
Alcor’s EGT instruments can help pilots save on fuel costs through precision leaning. Alcor EGT instruments also provide a quick visual reference to peak EGT. Alcor instruments offer the best value in the industry being backed by a 3-year warranty and include all.
ALCAL 2000+ System Tester
The ALCAL 2000+ is an all-in-one device designed to accurately calibrate and troubleshoot EGT/TIT/CHT, Type K, J, and E thermocouples and Alcor indicators. The tester will simulate thermocouple output millivolts so that instruments can be calibrated on the ramp or in the shop. The ALCAL 2000+ will also receive a millivolt input while testing Alcor and other brand thermocouples installed in its proprietary heater for accurate analysis at operating temperatures.
The ALCAL 2000+ is also designed to check the accuracy of an entire system or the individual components. While the thermocouple is in the heater, the instrument can read in the panel and recalibrate, as necessary, while simulating temperatures up to 1800 degrees Fahrenheit.
The ALCAL 2000+ comes equipped with 3 heaters (2 x EGT, 1 x CHT). EGT heaters will accept all Alcor thermocouples and competitive thermocouples with probe tip diameters up to .128 inches. CHT heaters will accept gasket style, bayonet style, and screw-in style probes. Recalibration/recertification of ALCAL 2000+ (and all previous versions of the ALCAL appliance) is only authorized by Alcor and is traceable to the National Institute of Standards and Technology (NIST).
TCP Fuel Treatment
Since the introduction of 100LL as the main fuel source for low compression engines, Alcor® has been the leader in providing pilots a fuel treatment that eliminates excess lead before it causes engine fouling. TCP is the only FAA approved aftermarket product of its kind. A simple one-shot treatment with every fuel fill-up help prevents lead fouling on valves and spark plugs. (Recommended dosage is 1 oz. or 30 ml of TCP for every 10 gallons of leaded fuel).
Give yourself peace of mind, keep your engine running cleaner, smoother and with more efficiency by relying on Alcor’s proven TCP fuel treatment.
- TCP syringe dispenser sold separately. (1oz/30 ml per 10 gallons of fuel)
