ABSTRACT:
A powder spray coating system has a controller configurable to a variety of different system configurations. Configuration data is keyed by an operator from menu prompts and stored for use by a microprocessor based operating program to operate the supply of powder and air to a powder spray gun. The microprocessor also presents information from monitored parameters of the system, including the supply air dew point which is monitored to provide warning signals of potential condensation in the system. Dew point detection is accomplished by measuring temperature and relative humidity and comparing the measurements with values for air at the maximum acceptable dew point. Alternatively, measurement of absolute humidity and supply air pressure are used to compute the dew point of the air which is compared with the actual temperature and maximum dew point temperature.
