GA-1 grease alarm signaling
The GA-1 is an alarm device for monitoring the thickness of the fat layer that accumulates in a separator. The system consists of a control unit GA-1, a GA sensor and a cable splice. The GA sensor is installed in the light liquid storage area and gives an alarm when the grease layer in the room reaches a predetermined level. The sensor is normally immersed in water. Its operation is based on the measurement of electrical conductivity of the surrounding liquid – water conducts electricity much better than fat.
GA-2 grease alarm with backwater signaling
The GA-2 is an alarm device for monitoring the thickness of the fat layer that accumulates in a separator. It also has an uplift sensor. The system consists of a control unit GA-2, two GA sensors and a cable splice. The GA Grease Sensor is installed in the light liquid storage area (grease) and gives an alarm when the grease layer in the room reaches a predetermined level. The sensor is normally immersed in water. Its operation is based on the measurement of electrical conductivity of the surrounding liquid – water conducts electricity much better than fat. The backflow alarm is suspended above the liquid level and gives a signal if the level in the grease separator rises and becomes too high.
