The Accuraspray 4.0 is an in-line thermal spray sensor that measures the spray plume temperature, velocity, dimension, orientation, intensity and stability. It is used in more than 400 spray booths around the world for quality control, process development and set-up.Talk to an expert
Consistent coatings come with consistent spray conditions
Our vision is simple: this is the industry’s watchdog for quality and consistency. That is why the fourth generation of the Accuraspray was built with one goal in mind: to democratize the use of spray sensors. It is dependable, versatile, easy to use and ready for a 100% automation of your spray booth.
The notion of stability is of immense importance in thermal spray. Recognizing the importance of process stability in production, we have introduced a process stability measurement in the Accuraspray 4.0. This new, state of the art stability analysis tool develops bench-marks for acceptable measurement deviations to compare with real-time standard deviations. This allows for increased repeatability with higher confidence in your measurements.
The Accuraspray 4.0 is designed to be versatile and cost-effective across all spray processes.
It can characterize all thermal spray processes:
The operator can easily switch from monitoring one process to another with just a click of Accuraspray’s web-based UI. High-level integrations of the sensors can also be performed using the unit’s HTTP API.
The measurement principle of the Accuraspray is entirely independent of the nature of the process it’s monitoring. The readings are certified using filtering algorithms so that any displayed number can be trusted. All the available metrics provided by the Accuraspray are factory calibrated on proprietary NIST traceable calibration stations that simulate the exact temperature, intensity and velocity ranges expected in the field.
For this fourth generation of the product, we envisioned that the Accuraspray 4.0 would spread the use of sensors for process parameters transfer, parameter development and process consistency to each and every booth in the world. We believe that building trust in the product’s consistency is the key to democratizing the use of sensors.
Ready for automation
Simple and easy to use, the Accuraspray 4.0 features a web-based, user interface making the information available by more than five viewing devices simultaneously. It can also be connected to the spray cells robot controller to automate the measurement before each spray session.
The evolution of all measurements over time is visualized on intuitive strip chart displays.
Production reports are generated with a single click in the user interface or through digital I/O.
The Autoset feature automatically adjusts all important Accuraspray 4.0 operating parameters according to spray conditions.
It’s important that our clients understand how easy it is to integrate the Accuraspray 4.0 into their quality process. We’ve divided this into the following five steps:
Tecnar takes pride in offering the best engineering warranty and support in the business so you can rely on Accuraspray 4.0 technology for years to come.
But don’t just take our word for it… take it from our customers.
