USB/RS 232 Meterless Sensors

• USB/RS232 Sensors: Plug Directly to your PC

Technology evolves toward simplification, makes cheaper and reduced-size working tools. Instrumentation for laser power measurement is subject to the same process. Traditionally the complete measurement set is made of a detector head connected to separate electronic unit to dis-play results: Laser Point has developed a series of laser power measurement instru-ments introducing new microelectronics cir-cuitry that has reduced the complete elec-tronics to the size of a USB 2.0 or RS-232 plug.
The result is new family of measurement tools that are smaller, more economical, easy to be embedded in laser systems ei-ther in machines or in laboratory.
The PC-Plug series of sensors has been spe-cifically developed for all those applications that do not require a display but where read-ings can be analysed and displayed on the now ubiquitous computer.
With simple plug and play functionality, no additional meter and at a lower cost, the new PC Plugs-USB/RS 232 sensors have all the power and sophistication of signal processing and software of a traditional power meter.
The RS-232 version is the most convenient platform to have power measurement integrated inside laser pro-cessing systems.
The PC-Plug-USB sensors get their supply power from the USB connection while the only requirement for RS-232 version is a + 12VDC input.

• Who will need the PC-Plugs?

The PC-Plug sensors have been primarily developed for applications that need a power measurement station on board of machines, like in laser marking, cutting, weld-ing, micro-machining; these instruments are also the perfect monitoring tool for other industrial applications such as laser burn-in or long-term reliability testing.
The PC-Plugs are also the best choice for service engi-neers and technicians who always travel with a laptop computer, because they will no longer need to carry separate instruments and additional weight.
Finally, thanks to their lower cost and smaller size, these sensors can be also successfully integrated in more standard laboratory applications that already use computer controlled instrumentation.
Laser Point has several years of experience in providing sensors and heads to OEM customers. Many of these users prefer to solve their laser measurement problem by purchasing the bare sensor and design a specific elec-tronics for signal processing. This is obviously a method but it has some limitations: for example the user must have both the tools and the know-how of adding accu-rate calibrations, the capacity of designing very low noise amplification and accurate A/D conversion which will drive to good stability and low noise measurements.
PC-Plugs sensors connect directly to a PC and now offer to system integrators or machine builders the possibil-ity to save precious resources to develop their own electronics and software. The PC-Plugs then simplify the work of OEMs who no longer need to take a thermopile sensor head and produce a calibrated power meas-urement instrument.
The PC-Plug approach provides the system designer the possibility of an immediate integration of a power me-ter with other devices of his system.
