Pressure/ Vacuum Sensors
-
There are three different types of pressures that can be measured using Premier Electrosystems' Pressure Sensors: Gauge, Absolute, and Differential. Gauge pressure is the pressure measured relative to the ambient atmospheric pressure.A typical application for a gauge pressure sensor is to measure liquid levels in a vented tank using the difference in hydrostatic pressure and ambient atmospheric pressure. Absolute pressure sensors will give the result relative to zero (a perfect vacuum). This is useful in applications where there is a direct effect of altitude on the pressure being measured. Differential pressure sensors measure the difference in pressure between two points. Differential pressure sensors are often used to monitor airflow in HVAC applications.

Differential Interferometer
10715A
-
The Keysight 10715A Differential Interferometer performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long term stability. The 10715A minimizes dead path, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The resolution of the measurement is twice that of a linear or single-beam interferometer.
