 | The Model 2002™, dual Sensor Vacuum Gauge, is a wide-range vacuum instrument consisting of a digital; microprocessor-based display unit; two sensing elements (micro-Pirani and piezoresistive bridge) in a single tube shell; and an interconnecting cable. Together, these components provide accurate vacuum measurement over 7 decades of pressure from 10-4 Torr to 1000 Torr.
This instrument is a new design approach, based on over 50 years of experience of Hastings Instruments with well-known pressure measurement techniques. A single tube contains both a Hastings patented thin film Pirani sensor and a piezoresistive sensor in a small and inexpensive package. The piezoresistive bridge is a direct force sensor which gives very accurate readings at high pressures from atmosphere down to less than 1 Torr without the concerns of gas composition.
The thin film Pirani measures pressures from a few Torr down to less than 1x10-4 Torr. An algorithm reading in the microprocessor ensures a seamless transition between sensors. Additionally, the two sensor outputs are used in a cross calibration mode to give even higher accuracy.
