Cold Spray Particle Diagnostics


Particle Size, Velocity, and Position Measurement for Cold Spray

HiWatch HR2

HiWatch HR2 is the system for most accurate particle size measurement while also measuring the particle velocity up to 2000 m/s and the plume density in the measuring area.

It is best suited for research and development of cold spray processes but can also be used for daily production monitoring and quality control.

HiWatch HR2 uses a SuperSpeed USB3.1 camera, which can be easily connected to any suitable computer or laptop with one free USB 3.1 or better interface.

Using a uniform laser backlight opposite to the camera allows for the best particle size measurement down to 5 μm in cold spray without sacrificing particle velocity measurement accuracy. All the necessary equipment is built into a single package, which can be mounted either vertically or horizontally on a suitable table, shelf or such for easy working.

HiWatch CS2

HiWatch CS2 cold spray diagnostic system is a compact and easy to use system especially for daily quality control. It collects fast the necessary data to ensure that the process is under control. It is also a good system for research and development of cold spray processes. It consists of a Gigabit Ethernet camera and an integrated invisible NIR diode sheet laser to illuminate the cold particles. Several safety features have been added for easy and safe use.

It can be used with any cold spray system and it measures reliably cold particle velocities up to 2000 m/s.

HiWatch CS2 measures particle position within the measuring area and the plume density as particles/sqmm.

HiWatch CS2 uses a GigE camera, which can be easily connected to any suitable computer or laptop with one free GigE port. For ease of use it utilizes PoE (power-over-ethernet) to power the camera through the LAN cable. An additional high-voltage power supply is included to power the diode laser.

HiWatch CS is an easy to use system that can fast collect the important data for making decisions how to optimize your process for best quality, lowest cost and least waste. Due to its compact size and effective shape it can be installed in a convenient location in the booth where the cold spray gun can be brought for checking the process before spraying any parts.


Thermal Spray Particle Diagnostics


Particle Size, Velocity, and Position Measurement for Cold Spray

SprayWatch 2S

SprayWatch 2S system is the top-of-the-line system giving maximum amount of information of thermal spray processes. It can be used in most thermal spray processes including Plasma, HVOF, HVAF, Arc and flame spraying.

All camera settings can be controlled from the computer keyboard outside the spray booth for added convenience. This is especially important when frequently measuring widely varying processes.

SprayWatch 2S has the widest range of focus distance setting enabling matching of the measured area with the spray plume width in most cases to catch maximum amount of particle data.

SprayWatch 2S is the only system that measures also particle size in Plasma, Arc and flame spraying.

SprayWatch 2S uses a high-speed USB camera, which can be easily connected to any suitable computer or laptop with one free USB 2.0 or better.

SprayWatch 4S

SprayWatch 4S is the most sensitive SprayWatch system especially for HVOF and HVAF processes, however, it works well also on the other processes.

It measures everything except particle size.

With SprayWatch 4S camera focus distance and lens aperture are adjusted mechanically on the camera inside the booth. But if only a few processes are measured in a booth then these settings can be probably set once and there is now needed to change between the processes. SprayWatch 4S is very portable. The camera weighs abt. 1 kg or two lbs. It is very compact and only needs a USB extension cord and +12 VDC power supply both provided with the system.

SprayWatch 4S uses a high-speed USB camera, which can be easily connected to any suitable computer or laptop with one free USB 2.0 or better. As an option the SprayWatch 4S camera can be also delivered with a 45 degree mirror end piece to allow for installation on the robot aligned with the thermal spray gun for continuous monitoring of the process when the spray time is longer or there is some other reason requiring continuous monitoring.

SprayWatch CMS

SprayWatch CMS, short for central monitoring system, is for larger installations with multiple booths equipped with any combination of SprayWatch thermal spray diagnostic systems.
It collects the measured quality data from all systems into a single central database computer with backups and other features.
It also allows control of the various SprayWatch systems connected to the central computer to ensure reliable and easy use.
