Introducing the SSD120 series of Transducers from Honeywell, specifically the SSD120-120N-RS-232 and SSD120-30N-RS232 altitude encoders. These transducers are designed for use in aviation and aerospace applications, offering reliable and accurate altitude measurement up to an impressive altitude of 30,000ft.
The SSD120-120N-RS-232 is a 120-pulse transducer, delivering 120 pulses per revolution. It operates on a 10-30Vdc input voltage and features an RS-232 serial output. This transducer is ideal for use in general aviation aircraft, providing precise altitude information for flight instruments and systems.
The SSD120-30N-RS232, on the other hand, offers a 30-pulse output per revolution. It also operates on the same 10-30Vdc input voltage range and features an RS-232 serial output. This transducer is suitable for use in larger aircraft or more demanding aerospace applications, where a higher pulse rate may be required for more detailed altitude information.
Both transducers in the SSD120 series are designed to be robust and reliable, with a rugged construction that can withstand the harsh environments found in aviation and aerospace applications. They are also calibrated at the factory to ensure accurate and precise altitude measurement, making them an essential component for any flight system.
In summary, the Honeywell SSD120 series of Transducers, including the SSD120-120N-RS-232 and SSD120-30N-RS232 altitude encoders, offer reliable and accurate altitude measurement for aviation and aerospace applications. With their impressive altitude range, RS-232 serial output, and rugged construction, these transducers are the ideal choice for any aircraft or aerospace system requiring precise altitude information.
The SSD120-120N-RS-232 is a pressure transducer with an integrated temperature sensor. It offers a measurement range of -40 F to 257 F and a high accuracy of 0.125% of full scale.

Pros:1. Wide measurement range allows for use in various altitude applications.
2. RS-232 communication provides ease of data transfer and compatibility with various data acquisition systems.
3. High resolution ensures accurate altitude readings.
Cons:1. Limited voltage range of 10-30VDC may not cover all power requirements.
2. RS-232 communication may not be the best choice for long-distance or high-speed data transfer applications.
Ending Conclusion:Both the SSD120-120N-RS-232 transducer and the SSD120-30N-RS232 altitude encoder offer unique features suitable for specific applications. The transducer's integrated temperature sensor and wide measurement range make it a versatile option for pressure and temperature measurement. The altitude encoder's high resolution and wide measurement range make it an excellent choice for altitude measurement applications.
However, the limited voltage range and use of RS-232 communication may be a concern for some applications. If your application requires a wider voltage range or faster data transfer, you may want to consider alternative transducers or encoders with different communication protocols.
Recommendation:If you're looking for a pressure and temperature measurement solution with an integrated temperature sensor and RS-232 communication, the SSD120-120N-RS-232 transducer is a solid choice. On the other hand, if you need an altitude encoder with high resolution and RS-232 communication, the SSD120-30N-RS232 altitude encoder is an excellent option.
When making your decision, consider the specific requirements of your application, such as measurement range, accuracy, voltage requirements, and data transfer needs. This will help ensure that you select the best transducer or encoder for your project.
