Lai Fukang compressor photoelectric oil level switch OUT276 LN/ INT276 LN oil level sensor
Refrigeration compressors, oil separators, etc. In order to effectively protect the oil level from high or low, the oil level switch must be installed at the corresponding position of high oil level or low oil level. The single point photoelectric oil level switch uses infrared light pair. The non-contact oil level detection of the liquid surface refraction and reflection principle has the advantages of high pressure resistance, chemical resistance, and full use of the optical monitoring device for monitoring the non-contact liquid level. The realization of the optical level monitoring function is accomplished by a prism screw-in part mounted at the desired measurement position and a detachable photodetector unit. The detector can be freely replaced without removing the oil level measuring prism assembly from the device under test, without affecting the sealing of the system. The relay is activated after the power supply voltage is turned on for about 3 seconds. The relay is turned off after a delay in the event of a low level or failure. When the fault is removed or the liquid level returns to a sufficient area, the relay is restarted after a delay. The relay passive switch contacts can be closed directly in the safety control circuit without the need for additional auxiliary relays.
The self-test feature during installation prevents assembly errors or operational errors.
