Leeds and Northrup 3050 Temperature Element Range

01/08/2009 8:24 AM

Hello everyone, I have been presented a problem dealing with legacy systems and equipment. I am performing an instrumentation study to determine either re-calibration or replacement of existing equipment due to an uprate in system parameters. I am looking for the range of a Leeds and Northrup 3050 temperature element that is presently installed. If anyone has this range and has a copy of an old catalog stating this I would appreciate this. It has taken approximately a whole day of searching the customers online documents and multiple Google searches.

Thanks ahead of time for your information.

I've been around L&N stuff for the last 35 years, but I just can't place a "3050". Are you talking about a temperature controller, or a primary element?

In my plant, (aero-space forging), we've replaced just about all of the L&N stuff with ether PLC's, or, Honeywell_UDC's.

The UDC's are inexpensive, so there's really no reason to keep the old L&N stuff around.

Unfortunately, I did not login when I submitted this question. I am looking for the range of a primary element with that model number. I was actually looking for old catalogs or tech manuals. Since I will be performing numerous instrumentation analysis for power uprates, I am looking for information on old instrumentation.
