Detector LN2 Monitor
Features
- Automatic protection against accidental detector warmup
- Delayed shutdown saves experiments
- Audible, visual and contact closure outputs
Description
The Model 1786A Detector LN2 Monitor protects LN2-cooled detector systems against accidental warmup by monitoring liquid level in the Dewar and providing audible and visual warning of low liquid levels. It provides a signal for remote shutdown of Detector Bias Supply which has an Inhibit input. This singlewidth NIM module is suitable for most dipstick and integral type cryostats, but is not suitable for portable cryostats.
When your LN2 sensor detects a problem, the LN2 Monitor has provisions for turning off high voltage when an alarm condition occurs to protect detectors and electronics from damage. Shutdown does not occur until at least 20 minutes after the condition is sensed, and well before total depletion of the liquid nitrogen, so ongoing experiments can continue without interruption.
The Model 1786A must be manually reset following a power interruption. This will prevent HV Bias from coming on automatically (and abruptly) when the power is restored.
