1F Piezo Diaphragm Vacuum Gauge

Part Number: 2-2108-001 and 2-2109-0XX

Our 1F piezo diaphragm gauge (also often called a vacuum pressure gauge, vacuum transducer,  or vacuum sensor) is a fast, robust, contamination resistant, and high accuracy low vacuum pressure gauge due to the piezo-diaphragm design. Note that by comparison to the 2A and 4A vacuum gauges which have a thermocouple gauge design, the 1E piezo-diaphragm vacuum sensor deisgn is gas-independent and can be mounted in any orientation.

The 1E piezo-diaphragm vacuum sensor will read from 10 Torr (10,000 microns) to 1000 Torr (10,000,000 microns, above atmosphere). It also has excellent accuracy over its range, and when paired with the MX200 or MM200 controllers it has ±5% to ±10% accuracy over the operating range of this vacuum gauge.

Why would you choose the 1E piezo-diaphragm vacuum gauge tube? An excellent question. Below is a list of some of the highlights of this vacuum transducer:
