Please explain the difference between Type K & Type J thermocouple CHT (Cylinder Head Temperature) sending units?The primary differences between the two thermocouples are: Measuring Range... Sensitivity... If you already own a gauge it is important that you use the correct thermocouple sensor type, otherwise the result will be incorrect CHT temperature readings due to mismatched sensitivities. Not inserting the EGT Probe tip completely into the center of the exhaust stream can result in low EGT temperature readings.Not inserting the EGT Probe tip completely into the center of the exhaust stream can result in low EGT temperature readings. After installing our Marine Series EGT Digital Pyrometer Kit on their boat a customer called to ask why their EGT temperature readings were hundreds of degrees below expected. They were reading 157 °F@ idle, 184 °F @ 1000 rpm, and 213 °F @ 1500 rpm. Explain 1/8" NPT Male ThreadA common question from our customers is how a 3/16" or 1/4" OD temperature probe can be used with an 1/8" NPT thread male compression fitting . Isn't a temperature probe with 3/16" or 1/4" OD too large for a compression fitting with 1/8" NPT male thread? EGT Probe Comparison ChartRecommended for fuel types: Gasoline, Natural gas, Nitrous oxide, & Alcohols I want to drill & tap a hole in the manifold & thread in the Compression Fitting. What tools will I need?We recently created an NPT Compression Fitting Technical Guide. The guide includes detailed information about the compression fitting dimensions, threads, ratings, assembly, and installation. You can download it from here: |
