PDI Probes:

Droplet size and velocity measurements

 

Artemis

The Artemis PDI Probe has been specifically designed for rugged, industrial and R&D applications that require turnkey operation. It measures size and one component of velocity of individual particles as they enter the measurement probe volume. Various spray statistics such as mean diameter, median diameter, and size-velocity correlation are computed and can be used to monitor and control the spray process in real-time.

The instrument incorporates an optical transmitter and optical receiver which are packaged in an environmental enclosure. The system is aligned and calibrated in the factory. Routine alignment and calibration is not required. The high powered DPSS lasers built into the transmitter provides stability, compactness, ruggedness, and high reliability; it eliminates the need for inefficient and unreliable fiber optics and bulky Ar-ion lasers.

 

Demeter

The Demeter PDI Probe has been specifically designed for agricultural applications that require turnkey operation in the field under difficult operating conditions. It measures  the size and one component of velocity of individual spray droplets as they enter the measurement probe volume. Various spray statistics such as mean diameter, median diameter, and size-velocity correlation are computed and displayed in real-time. The probe can be used for characterizing spray nozzles, studying spray deposition, and measuring spray drift. The probe can also be used for wind tunnel testing and can be mounted in an aircraft for aerial spraying applications.

The probe includes an optical transmitter and optical receiver which are packaged together in an aerodynamic, water-tight enclosure. Demeter electronics (ASA and computer) are mounted in a vibration isolation rack system which also serves as the shipping container. The system is aligned and calibrated in the factory. Routine alignment and calibration are not required. The operating measurement size range can be manually changed by the user. The high powered DPSS laser built into the probe provides stability, compactness, ruggedness, and high reliability; it eliminates the need for inefficient and unreliable fiber optics and bulky Ar-ion lasers.

Theron

TheronPDI Probe has been specifically designed for rugged, outdoor applications that require turnkey operation. It measures size and one component of velocity of individual particles as they enter the measurement probe volume. Various spray statistics such as mean diameter, median diameter, and size-velocity correlation are computed and can be used to monitor and control the spray process in real-time.
