D 120-P2-T Encoder General Description:
Trans-Cal Industries has designed a low cost altitude reporting system that will meet and satisfy all the requirements of TSO-C88. The system is completely independent of the pilot's altimeter and consists of a temperature compensated pressure sensitive dual aneroid capsule, associated mechanical linkages and an encoder module. The encoder module is an optical type utilizing Gallium Arsenide (GaAs) light emitting diodes, a code disc, solid state detector and associated electronics.

Note: The D 120-P2-T Series Encoders are now built to order only. Please allow 6-8 weeks ARO.

General Specifications:

TSO-C88...................	This digitizer conforms to the applicable requirements of Technical Standards Order C-88 for combination devices.
Range.......................	The digitizer has an active code range of -1000 feet up to +35,000 feet.
Code Input...............	The digitized altitude output format is in accordance with US national standards for common system component characteristics for the IFF Mark (SIF)/Air Traffic Control Radar Beacon System SIF/ATCRBS and the international (ICAO) standard code for SSR pressure altitude transmission.
Accuracy.................	The digitizer reproduces the pressure altitude input in digital form with a tolerance of +/- 75 feet, measure at the transition points against a NIST traceable standard, or is matched within +/- 125 feet of the primary flight altimeter. Units operating in excess of 30,000 feet must be factory matched to the primary flight altimeter.
Identification...........	The following is legibly and permanently marked on the nameplate: a. Trans-Cal Industries, Inc. Van Nuys, CA 91406 b. Automatic pressure altitude digitizer equipment c. Range (as applicable) d. Model (as applicable)
