How do you test Isspro pyrometer?
Clip the yellow tester lead wire to the yellow lead wire and red tester lead wire to the red lead wire. 2. Turn the tester ON. The tester meter should drop below 300°F indicating lead wire and thermocouple show continuity and should be operating properly.
Are Isspro gauges good?
They are both good gauges. I run auto meters personally and have never had an issue with them. The only negative I can think of which is not really the gauge failing.
What is a isspro pyrometer?
The ISSPRO Electric Pyrometer Gauge R605 has a gauge size of 2-1/16 inches and uses a type K (chromel-alumel) thermocouple that are designed to high temp applications. The gauges scale reads both 300-1500 degrees Fahrenheit and 200-800 degrees Celsius.
What is pyrometer gauge?
A pyrometer is a temperature gauge designed to measure high temperatures above those measurable with an ordinary thermometer. It consists of a temperature-sensing probe (thermocouple) that is placed in the area, or flow, to be measured. The purpose is to measure and display EGT in degrees Fahrenheit (F.).
How do you test an EGT gauge?
How to test an Exhaust Temperature Gauge – aka – Pyro EGT gauge
- On a work bench away from the vehicle connect the gauge up to a 12 volt source.
- Attach the temperature sensor (probe) to the gauge.
- With a BBQ Gas Lighter heat the probe end – being careful not to burn yourself.
Where are Isspro gauges made?
Isspro’s factory is in Portland, Oregon, and they also offer custom gauge faces.
Does a pyrometer need power?
NOTE: Hewitt pyrometers require no power. NEVER apply vehicle voltage to pyrometer terminals, damage beyond repair will occur.
What does a pyrometer gauge show you?
Where should I put pyrometer?
Pyrometer Installation: On both the 12-valve and 24-valve engines, the best place to locate the thermocouple in the exhaust manifold is about two inches before the turbo flange gasket surface toward the engine.
What is the highest recommended pyrometer temperature?
It depends on where the pyrometer is sensing. If you install pre-turbo then your safe point is a maximum of 1200 F or so, (it doesn’t vary between engines much as it’s based on the melting point of the aluminum pistons).
Why are EGTS so important?
The exhaust gas temperature (EGT) pyrometer can be one of the most important gauges on a turbo-diesel-powered vehicle. It can warn the driver of situations that are potentially damaging to the engine, and it can also be used as a guide for optimizing fuel economy. Diesel engines are not indestructible.
