Pyrometer

[Rob Robinson]

Bill somewhere in the recesses of my mind I recall something about the length of the wire being important. Thiswas in connection with the install of an oil temperature sending unit. If I recall correctly the instructions said not to shorten the wire. Not sure if this applies to a pyrometer.

I have been trying to find some info on the pyrometer circuit. The question I have is:
Is the length of wire predetermined on this gauge?

the closer to the turbo the hotter the reading. it is exponential. the wire length is critical to the accuracy of the gauge and has to be taken in to account in change outs and calibrations. thermcouples are very tricky little pieces of platinum --- On Wed, 2/4/09, Leroy Eckert wrote: From: Leroy Eckert Subject: RE: [WanderlodgeForum] Pyrometer To: WanderlodgeForum@yahoogroups.com Date: Wednesday, February 4, 2009, 6:00 PM I do not have the schematic of the circuit. I would bet the placement of the probe location was predetermined to fit the normal temperatures published in the manual. I would imagine the closer the probe is the turbo outlet the hotter the reading and visa versa.

The thermocouple acts as a probe and produces a small signal measured in millivolts, sometimes amplified depending on the pyrometer gauge circuitry. Obviously, sound electrical connections are important.

My guess is that they are manufactured at various lengths already made-up. I have seen the excess coiled and ty-raped.
