The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Varian - Model: L6491301 - Condition: Used and in Excellent Condition - Price: $595.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 3.5 lb, estimated - Shipping dimensions: 12X9X6 in, estimated ## Categories - Lab & Analytical > Lab Parts (primary) ## Details Part Numbers: L6491, L6492, L6491301 ## Function Electronics board for capacitance diaphragm pressure sensors; provides excitation to the diaphragm, converts capacitance changes into a proportional electrical output, and conditions the signal for host measurement systems. It offers stable bias, calibration and temperature compensation, low-noise amplification, and fast response to dynamic pressure changes, enabling accurate, high-sensitivity vacuum pressure sensing across the intended range. Output is suitable for integration with standard readout interfaces and control loops within vacuum instrumentation. ## Images - - - -
