Bimba Volume Pneumatic Cylinder 5.5" with dual sensors for Fill & Empty

Description

This is a Buy It Now listing for a Bimba volume cylinder, in used but excellent condition.  This came off some recently retired medical equipment.  In its previous usage it had helium in it, at somewhat less than 4.5 psi. We don't know the specification limits of this cylinder, so that pressure was stated for your approximate reference. There are two 3-wire magnetic sensors, which are user adjustable in position, to sense when the volume has reached pre-set "full" and "empty/Low" levels within the cylinder.  There is a venting hole at the end with the protruding shaft (see picture).  The helium that was previously used came in/out of the cylinder via the small tube (~ 1/8" - 1/16" ID) on the square end of the unit. There are two threaded mounting holes for securing the unit in place.  This is a high quality stainless steel unit, and should be virtually like-new in functionality. The central cylinder is 5.5" long, not including the square end piece or the protruding shaft/nut piece on the opposite end.  The units are labelled "0202-00-0133_C" and "06 5 28_BIMBA".
We have about (12) of these available, although this listing is "for each".  If you need more than we show available, please contact us by Ebay's "Contact Seller" email facility and let us know how many you would like and we can arrange a reduced shipping charge for multiple units purchased together.
We are not able to test these, but if a buyer finds them to be defective we will replace (not refund) the unit with another unit.  Please note that on most of these, the connectors on the 3-wire sensors have been cut, and may be as short as 3" long but will typically be much longer, and the rubber or clear tube (seen on the bottom end) may not be included.  Our first picture for some reason shows the manufacturer's brand colors in grey, but in actuality it is in Red, as shown in our last picture, if that makes any difference.
"Used" condition, so only the hardware is guaranteed for 30 days.
This will not be shipped in the original packaging, and there are no user manuals included or anything else not specifically mentioned in this listing.
Shipping Policy: We ship weekdays, Monday through Friday, national holidays excepted. We ship in the least costly manner unless instructed otherwise at checkout.
