About the AHI3000 High Specification TEDS Pressure Transducer
The AHI3000 TEDS Ready (Transducer Electronic Data Sheet) contains the critical information needed by an instrument or measurement system to identify, characterize, interface, and properly use the signal from an analog sensor.
IEEE 1451.4 defines the method of encoding TEDS information for a broad range of sensor types and applications.
The unique Silicone-on-Sapphire sensor provides outstanding performance and gives excellent stability over a wide temperature range.
The advanced sensor design consists of a piezoresistive silicon strain gauge circuit, which is epitaxially grown onto the surface of a sapphire diaphragm to form a single crystalline structure.
The sapphire sensor element is then molecularly bonded to a Titanium alloy sub-diaphragm. This enables the sensor to endure higher over- pressures and provides superb corrosion resistance. The sensor exhibits virtually no hysteresis and excellent long-term stability.
With outstanding insulation properties, the sapphire substrate allows the sensor to operate over a very wide temperature range without loss of performance.
