|
 |
TYPE : 38SFS |
|
|
SUPERFREEZE Float switch, type 38SFS is an electro mechanical float switch designed to provide a reliable, electro- mechanical response to liquid level changes. The simple and rugged design ensures long life performance and reliable operation for many usages such as, |
- Level control by liquid fill solenoid valve
- High level cut-out or alarm
- Low level cut-out or alarm
- Low level pump cut-out
- Level control by liquid exit solenoid valve
- Level indication by pilot light
- Transfer drum operation
|
The design incorporates a mechanical float which will operate in the refrigerant. When the set level is reached an electrical volt free micro switch will be activated. |
FEATURES |
- Based on SUPERFREEZE float type 38SLC
- DIN, ANSI and FPT / NPT flanges
- Switch assembly can be rotated at 360` for easy installation.
- Adjustable liquid level differential switch point
- Electro magnetic micro switch, mechanically activated.
- The complete switch box can easily be replaced with out any interference with refrigeration system
- Switch box supplied with DIN plug for ease of installation and service
- Counter flanges are included.
