Rotalock optical level swtich for HVAC systems

The Rotalock optical level switch is specially designed for use in level monitoring for controlling the oil or refrigerant level in HVACS&R systems.

The bodies are made of steel and sensor dome is fused with the body so if well mounted the sensor is leakage free.
The two parts design allow the fast replacement of the electronic parts without depressurizing the system.

Main features

Lubricating oil reservoir level monitoring
immediate sight glasses replacement
Easy maintenance
critical fl uid level detection on machine tools, chillers and any industrial OEM equipment
monitoring refrigerant liquid level in both horizontal and vertical liquids receivers
monitoring oil level in oil reservoirs
P.O.E. Oil and Refrigerant Fluids compatibility
