[time-nuts] Foxboro pressure sensor question for maser

Hi,

I am needing the documentation on how to hook up a Foxboro pressure
sensor that is being used to measure the pressure out of a heated hydride
Hydrogen source for a passive maser package.

The maser package has no identifying logos or indication of who built it.
It was built in the 1983 to 1985 time frame from date codes on ICs.

The Foxboro sensor is in a transistor package similar to a TO-5 but
bigger. It has six leads out the bottom with some 1% resistors attached.

The numbers on it are 0-25A which I assume is the part # as well as the
pressure range, and 2183-14 which I think is the date code as well as the
name Foxboro.

I contacted Honeywell and also Foxboro / Eckardt Product Support who
referred me to Honeywell. But they could not help!

Thanks for any help!
