The Ashcroft DXLdp Series differential pressure transmitters are variable capacitance sensors within a glass-clad silicon chip. The patented Si-Glas™ technology combines the inherent high sensitivity of a variable capacitance transducer with the repeatability of a micromachined, ultra-thin silicon diaphragm.
The Ashcroft Si-Glas sensor enables precise measurement and control of very low pressure. Although the ultra-thin silicon diaphragm deflects only a micron, the sensor is 100 times more sensitive to pressure than available silicon piezoresistive pressure sensors. The Si-Glas sensor is composed of only sputtered metals and glass that is molecularly bonded to silicon. There are no epoxies or other organics in the sensor to contribute to drift or mechanical degradation over time. The glass-clad silicon diaphragm withstands extreme overpressure as well as severe shock and vibration.
Other features of the Ashcroft DXLdp Series differential pressure transmitters include front access test jacks, LED range status indicators, DIN rail mount, 2:1 range turndown options, CE standard with all outputs and on-board voltage regulation.
