New MEMS vacuum transducer evaluation kit

12-08-2021 | Posifa Technologies | Design & Manufacture

Posifa Technologies has released an evaluation kit for its PVC4000 series of digital MEMS Pirani vacuum transducer, which vows to disrupt the portable vacuum gauge market by facilitating low-cost, easily replaceable sensor probes that may be switched without needing the vacuum gauge itself to be recalibrated since all the calibration data is stored in the probe itself.

The PVC4000EVK evaluation kit enables OEMs to quickly test drive the company's MEMS vacuum sensing technology for digital vacuum gauge and related applications. The kit comprises a PVC4000 transducer packaged in a brass housing with a 1/4 SAE male flare fitting or a stainless-steel housing with a KF16 fitting that enables it to be fitted into any vacuum environment for quick evaluation. The transducer in the kit is calibrated and produces a digital output in microns. The kit's PC-based diagnostic software provides users access to various sensor readings and configuration data stored in the transducer.

"With the PVC4000EVK, vacuum gauge OEMs can find out in an hour's time what our digital Pirani vacuum sensor technology can do to help them offer customers more flexible and versatile end products that build brand loyalty," said Peng Tu, president, and CEO at Posifa Technologies.

The transducer included in the evaluation kit is calibrated for the vacuum range between one micron and 760,000 microns. Through the transducer's digital I²C interface, the user may access the sensor's raw output and the calibrated vacuum reading. The kit incorporates a custom wire harness that connects the sensor and the I²C to a USB adapter board, enabling the user to read sensor data from a PC in minutes.
