In my collection of probes, I have a P6610 physical measurement amplifier and three P6610 pressure transducers. I don't have any documentation and a search of the usual sources has come up empty. Wondering if anyone here knows anything about this probe or, better yet, has some documentation they would be willing to share.

Thanks - Bill

Are these Tek products? If so, look at the engine analyzer line from way back. One of the Tek "Concept" book series addresses this so may have some pertnent info.

I had to look. Here it is. Good luck.

Here's the rest.

If your probes don't seem to be Tek or related to engine analyzers, then also look at HP's foray into laser interferometer systems, which had some transducers for barometric pressure, temperature, and other physical stuff, to compensate for effects on the laser optics. HP also had some other pressure transducer stuff related to HPLC and GC in their analytical equipment lines, up to around 6,000 PSIG.

See

It has an alternative part number

(Not my auction just a Google result)

Thanks. The ebay listing is for the pressure transducer part of the probe set I have. Definitely labeled as Tektronix gear. The probe assembly has a Lemo power cable and a P6137 style BNC connector and body. Maybe it was a custom probe for internal use or a particular customer. Just trying to figure out if I can use the probe amplifier for anything interesting but I'd definitely need to find a schematic first.

The Novasensor product line is still around. Jim Williams's AN61 () includes several application circuits that might help you think about what could be in the probe.
