1E Piezo Diaphragm Vacuum Gauge

Part Number: 2-2106-001 and 2-2107-0XX

Our 1E 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 1 Torr (1000 microns) to 1000 Torr (1,000,000 microns, slightly 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:
