NIM BIN – PGT 326A LN2 Auto Fill Controller – Parts / Repair Used

Princeton Gamma-Tech 326A Liquid Nitrogen Auto Fill Controller (NIM)

Condition:

Used and in good cosmetic shape. The external connector on the back has been removed, but testing found no other functional issues. Due to the missing rear connector, this unit is sold AS-IS for parts or repair.

Here’s what we know about it:

• Automatic LN2 control: Manages LN2 filling for detectors needing cryogenic cooling, such as silicon and germanium radiation detectors.
• Level monitoring: Detects low LN2 levels and activates the refill process.
• Valve control: Works with a solenoid valve to regulate LN2 flow from supply to detector dewar.
• User controls: Front panel allows adjustments to fill settings and status checks.
• NIM compatibility: Fits in standard NIM bin setups for seamless integration into nuclear instrumentation systems.
• Applications: Often used with HPGe gamma-ray spectrometers, automating the LN2 filling process to keep detectors running smoothly.

Great for maintaining stable cooling in cryogenic detector systems, though some modification will be needed due to the missing rear connector.
