3-42 Component Description

3.12.5 Low Fluid Sensors

The low fluid sensor automatically detects when material in the syringe or cartridge is low and alerts the

operator by activating the light beacon and displaying a message in the Fluidmove Run Window. The

operator can continue the dispensing process for a defined number of boards or stop the dispensing

process to change the syringe/cartridge. Both magnetic and capacitive sensors are available. Contact

Asymtek for specific application suitability.

3.12.5.1 Capacitive Fluid Level Sensor

The capacitive fluid level sensor (Figure 3-28) monitors the fluid level inside a syringe by detecting

changes in localized conductivity. During use, the sensor face rests against the syringe, touching the

cartridge casing. When the fluid level inside the syringe drops below the sensor face, the conductivity

change causes an interrupt and a low fluid warning is issued to the operator. The sensor connects to a

receptacle on the electrical bulkhead labeled

LOW FLUID SENSOR. The sensor has a 24 AWG (PVC-

insulated) copper conductor with a nominal sensing range of 5 mm (0.2 in.). The sensor is held by a

mounting bracket that attaches to the valve bracket.
