Key Features
Self-Contained Unit
Integral oil level sensor and solenoid manage oil level supply in a single junction-box configuration.
Gravity-Based Float Sensing
Signal is generated by a gravity-based float, reducing errors from foaming compared with optical sensors.
SPDT Alarm Output
SPDT alarm output supports compressor shutdown and external alarm signalling.
LED Status Indication
LED alarm and status indications provide visual monitoring of oil level conditions.
Debris Retention Magnet
Integrated debris retention magnet supports reliable operation in refrigeration circuits.
