Usually part of the gun/application head. A control valve that is activated by
an electromagnetic coil.
Solid State Relay
Electronic assembly without mechanical parts but with the function of an
electromechanical relay.
Solvent
Solvents are liquid, organic materials and their compounds, used to clean
adhesive off of surfaces. Solvents are slightly volatile. Special regulations
must be followed when using solvents.
In Nordson literature, the solvent is always the substance prescribed by the
hot melt manufacturer.
Substrate
The product - fabric, foil, etc. - to which a material is applied.
Tach Generator
A component that generates electrical voltage (pilot voltage). The voltage is
proportional to the speed at which the tach generator is driven.
Temperature Sensor
A part of a temperature control system that compiles the temperature and
transmits it to the control system.
Resistance temperature sensor are used in
Nordson units.
Thermostat
Component that regulates temperature. It is usually an electrical switch that
switches at a certain or set temperature. The difference between the
temperatures at which the unit switches on and off is called hysteresis.
Transformer
Voltage converter.
Used in Nordson units to convert the customer's line voltage to the operating
voltage.
