echnology manufacturer Pfeiffer Vacuum Fab Solutions has launched the TPG 202 Neo, a piezo/pirani
handheld gauge designed to measure pressure in various industrial and laboratory environments.
COMPACT AND INTUITIVE DESIGN The product is compact, designed for usability and covers the range from 5E-5 to 1.2E3 hPa. A silicon cover means it can also withstand demanding environments. The company believes that the gauge will become the standard for reliable and efficient vacuum measurement tasks in the laboratory as well as field service operations. The device uses both a Pirani and a Piezo sensor.
THE PIRANI SENSOR The pirani sensor measure the electrical resistance of a filament wire where it varies with temperature. As
the pressure changes, heat conduction through the gas changes, altering the temperature of the filament and providing data.
THE PIEZO SENSOR The piezo electric sensor uses the piezo electric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge.
EASY DATA MANAGEMENT One of the key features of the TPG 202 Neo is its large internal mass storage, which allows for continuous data collection over extended periods. “This feature simplifies data management, as users can easily export collected data via a USB-C connection without needing special software,” says Sedrick Njomou, product manager at Pfeiffer. The TPG 202 Neo is also equipped
with a large LCD display that supports graphic data plotting, enhancing the user experience by providing clear and precise data visualisation. “This makes it easier for engineers to interpret data and make informed decisions based on real-time information,” adds Njomou.
SUITABLE FOR MANY APPLICATIONS The product can be used for many applications including measuring rough and medium vacuum environments to determining pumping speed as well as performing simple leak detection using pressure gradient or increase measurements. This makes the TPG 202 Neo a “reliable and efficient solution for daily measuring tasks across various industries,” according to the company.
