When hammering on a wing union fitting, it’s not uncommon for there to be a “slight miscalculation” in the swing. When this unfortunate event takes place, fate ensures that some expensive equipment is nearby waiting to take the blow. All too often, the stray hammer smashes into the connector on a hammer union pressure transducer, which causes breaks in the wiring and leads to an inoperable pressure sensor.
Over the past few years, we have been approached by some of our customers asking for a solution to this problem.
Quite often, we have run into the assumption that by opting for a potted-in cable instead of a connector, you will reduce the chances of broken contacts from a poorly judged hammer swing. This, unfortunately, is not the case. We have learned through trial and error that using the potted-in cable instead of the connector does not add any protection. In fact, we have had more returns with the potted configuration than the connector from broken wires.
So what’s the best way to protect the connector on your hammer union pressure transducer? The answer is pretty straightforward - a protective cage.
As far as the cable is concerned, we recommend that you choose whatever connector option works best for you, whether it be a 4 pin bayonet connector or 2 ft. of cable with a pigtail. Just make sure that you order a sensor with the protective cage option.
We should mention that the cage will not make your hammer union pressure transmitter invincible to all potential hazards, but it will provide an added layer of protection from blunt force trauma.
As a bonus, the protective cage functions as a handle, making it easier to transport the transducer.
If you would like to get pricing on our hammer union pressure transducer with the protective cage option, or if you have any other questions, please contact us.
