New Posifa Technologies Presents PVC6100 series of MEMS Pirani

Posifa Technologies has launched its new PVC6100 series of MEMS Pirani gauges for atmosphere (ATM) to medium vacuum applications. Featuring a wide range from 10-4 Torr to ATM, the gauges deliver high accuracy and long-term stability while offering an interchangeable probe and customizable output voltages to lower the total cost of ownership for users by eliminating the need for calibration of replacement probes.

PosifaThe devices released today will be used in freeze dryers, mass spectrometers, distillation equipment, cryogenic cylinders and tanks, vacuum furnaces, and load-lock vacuum systems. To ensure precision and uniformity in these products, the gauges’ sensing element is based on Posifa’s second-generation thermal conductivity chip, which is made with world-class microfabrication processes. For exceptional sensitivity and repeatability, the sensor chip measures thermal conductance in an embedded cavity with an integrated thermopile.

With a low internal heater temperature just slightly above the ambient, PVC6100 series gauges are much less susceptible to contamination than filament-based Pirani devices, enabling higher reliability and longevity. In environments where heavy contamination is unavoidable, users can simply replace the devices’ interchangeable probe — which is individually calibrated and incorporates the sensing element and digital electronics — to reduce system costs and downtime.

PVC6100 series gauges offer 0 V to 10 V analog output through their FCC-68/RJ45 connectors. The output voltages can be customized to emulate those from other manufacturers’ devices, enabling plug-and-play replacement for enhanced performance and reduced total cost of ownership without any need to change system software or connection hardware.
