Kriwan 22A298 Delta-P II Electrical Part For Level Monitoring The Lubrication System
KRIWAN level monitoring offers different sensor versions for the monitoring of the liquid level in refrigerant compressors, oil and refrigerant receivers and oil separators.
replaces Emerson model 3164918
Monitoring of the minimum / maximum liquid level
APPLICATION
Universally applicable for oil management in systems with conventional refrigerants and lower temperature requirements
ADVANTAGES
- Universal applicability with different media (refrigerant, oil, fruit juice) due to optical measuring principle
- Two-part design enables replacement without evacuation of the system
- Increased safety through screw-in detection and self-monitoring
- Can be used in the safety chain due to potential-free relay
- Vibration resistance enables use on compressors
- Quick and uncomplicated recognition of the safety status through LED status display
For Emerson
APPLICATION
Monitoring the lubrication system is especially important in refrigerant compressors.
KRIWAN's differential pressure monitoring is a very reliable method for piston compressors.
It consists of two parts; the DELTA-P II electrical part and a separately available screw-in part.
The electronic electrical part can be mounted or replaced without opening the refrigeration circuit.
FUNCTIONAL DESCRIPTION
The difference between high pressure and suction pressure in the screw-in part influences a movable piston. Its position is registered
without contact by the mounted DELTA-P II electrical part and evaluated.
After the compressor starts up and the starting transition time has elapsed, the differential pressure monitoring is active.
Fluctuations in the differential pressure are taken into account by an extension of the switch-off times (time integration). A missing differential pressure leads to a locked switch-off.
Restarting is only possible after a reset.
The potential-free contact can be looped into a safety circuit without a supplementary auxiliary relay.
The integrated installation check monitors the proper assembly.
A built-in LED signals the current status.
