SnakeEye™ Thermal Switch
Infrared Thermal Inspection for Hot Melt Adhesive An Exergen OEM/Factory Automation Product
SnakeEye.3-LTE - CLICK HERE for DETAILED SPECIFICATIONS
Now you can have 100% inspection of hot melt adhesive to your product . . . not only its presence, but its position as well. Employing new state-of-the-art infrared techniques (patent pending), the SnakeEye provides photocell simplicity of operation, with extraordinary thermal sensitivity to "see" each and every bead as it is applied in real time.
The SnakeEye Thermal Switch is installed immediately downstream of the hot melt applicator, and provides 2 on/off photocell type of switches as it sees the thermal presence of the leading and trailing edges of adhesive. Sensitivity level is adjustable.
