Overview

Introducting the smallest, lightest and lowest power consumption altitude encoder, the Nano.

The SSD120-35N-RS232 is an all solid-state Altitude Encoder. This device provides a rugged and reliable means of measuring air pressure and converting this measurement into the ICAO parallel data for Pressure Altitude Transmission.

This unit also provides altitude data on two asynchronous RS232 outputs. The serial data protocol is individually selectable for each output and is commonly used to provide pressure altitude data to GPS, Auto-Pilots, Transponders and other navigation devices.

Resolution of the serial altitude data may be set to 100 feet or 10 feet. A data protocol offering one-foot resolution is available, as well as one protocol offering altitude data in meters.

Featuring:
  • The Best Warranty in the business: 42 months manufacture direct replacement. If your Trans-Cal encoder experiences a warranty covered failure, we will replace your unit with a brand new unit with a new 42 month warranty.
  • Average MTBF: 9.7+ years. That’s right: Trans-Cal encoders are among the most reliable on the market, commonly providing reliable service for over 10 years.
  • Pin for pin replacement for most other manufacturers encoders.
