100 PSI-A-DO

Overview

The Amphenol All Sensors Corporation 100 PSI-A-DO is a board-mount absolute pressure sensor utilizing proprietary surface mapping technology. It features a 6-SIP package with a 0.19-inch (4.8mm) port and delivers a 12-bit digital serial output, supporting 14-bit high-resolution mode. The device operates within a 0 to 100 psi range and offers accuracy between 0.1% and 0.25% full scale. It provides SPI and MICROWIRE/PLUS compatibility alongside a bidirectional TTL asynchronous interface at 9600 or 19200 baud.

Feature Summary

• Generates fully digital output using proprietary surface mapping technology to minimize temperature and pressure errors.
• Supports multiple communication protocols including SPI, MICROWIRE/PLUS, and bidirectional TTL asynchronous modes.
• Features high-resolution 14-bit output capability with superior offset, span, and linearity characteristics.
• Allows host querying of model information, pressure range, and serial number via command set.

Applications

• Industrial instrumentation
• Medical equipment
• Factory automation systems

Procurement Notes

Verify component status as the 100 PSI-A-DO is listed as obsolete in public records. Confirm availability through authorized distributors or surplus channels. Ensure the replacement strategy accounts for the discontinued status by evaluating compatible alternatives from the same manufacturer series. Validate that the specific package type and interface requirements match the target application design before procurement.

Selection Notes

Select this component for applications requiring absolute pressure measurement in non-corrosive environments such as air or dry gas. The digital output eliminates analog signal conditioning needs. Consider the 6-SIP package size and 0.19-inch port dimensions for mechanical integration. Verify that the host system supports the required SPI or MICROWIRE interfaces for proper data acquisition.

Part Context

This part belongs to the ADO series of digital output pressure sensors from Amphenol All Sensors Corporation. The series is designed for board-mount industrial applications. It shares functional similarities with other models in the GA142 family but is distinguished by its specific 100 psi range and digital interface capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status of this specific model. Evaluate other models within the Amphenol All Sensors digital pressure sensor portfolio for potential cross-replacement based on interface and range compatibility.
