The Model 2002 Dual Sensor Vacuum Gauge is a wide range vacuum instrument consisting of a digital microprocessor-based display unit, two sensing elements (microPirani 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 1x10-4 Torr to 1000 Torr. This instrument is a new design approach based on over 60 years of experience by Teledyne Hastings Instruments (THI) with well-known pressure measurement techniques. A single tube contains both a THI patented thin film Pirani sensor and a piezoresistive sensor in a small, rugged 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 1x10-4 Torr. An algorithm residing 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.
