EGT Probe & 8 foot extension for Zeitronix
... people are viewing this right now
Description An EGT probe suitable for use with the Zeitronix Zt-2 wideband controller and data logger. Works with any system requiring a k-type probe. It comes with the common k-type connector and is supplied with an 8 foot extension cable. It has a 1/8 NPT thread for mounting into the exhaust manifold. If the manifold is of the tube type, or its wall thickness is not suitable for tapping then you may also need the stainless steel 1/8 NPT weld-in boss that we stock. Notes: On turbocharged engine the EGT probe should be placed before the turbo. A high temperature drop occurs across the turbocharger which will throw off any EGT readings taken after a turbo. This temperature drop is variable and so the preferred EGT probe location is before the turbo. Place the EGT wires as far as possible from the ignition components such as plugs, plug wires, and coils. Since the ignition components carry thousands volts they are a very powerful sources of EMI noise. The EMI noise may be inducted into the EGT wires. The Zt-2 has a sophisticated common noise rejection circuit, however the EGT signals are in mili volt levels (0.001V) where the ignition carries tens of thousands (10000) volts and placing the EGT wires near the ignition components may result in false peak EGT readings.
