[Dsg-rich] Replacement PT for RICH air-cooling buffer tank

[Tyler Lemon]

Hello Bob,

We have received the new Dwyer PTs for the RICH air cooling system's buffer tank. The two PTs (one to install and one spare) have had connectors put on by Mindy so they should be able to be swapped with the old one and just connected to the same cable.

Since the new PTs are different model and brand than the old one, the changes would need to be looked over by a DA to verify they are compatible with the pressure system. The PTs are Dwyer Instruments model 628-11-GH-P8-E4-S5. It's range is 0 - 150 psig and the fitting is a 1/8" male NPT. Attached is the manual that has its complete specs and pressure ratings.

We also have the necessary lines to connect the second compressor to the buffer tank and to the drain line. The lines and PTs are in EEL 121c for when they are to be installed.

Best regards,
Tyler

Hi Bob,

We have submitted a PR for two new PTs (one replacement, one spare) for the RICH air-cooling system's buffer tank.

Once it comes in, we will put the appropriate connector one them and give them to Hall B Engineering for installation/storage.

The new PTs are not the same model or brand as the old one, so the changes would need to be looked over by a DA (Bill Crahen was the last DA that worked on RICH's gas system).

The new PTs are Dwyer Instruments model 628-11-GH-P8-E4-S5. It's range is 0 - 150 psig and the fitting is a 1/8" male NPT. Attached is the manual that has its complete specs and pressure ratings.

If you need any more information on the new PTs for the DA or anything else, let us know.

Best regards,
Tyler
