E-TX-21-0014 Rev IR  Installation Manual, TXA201 Triaxial Accelerometer 

 

1  GENERAL 

1.1  Purpose 

This manual provides Installation Instructions for the TXA201 Triaxial Accelerometer, 

including information on mounting, testing, and physical and electrical interfaces.  
The TXA201 measures accelerations along the longitudinal, lateral and vertical axes of 

the aircraft. It does not measure angular acceleration rates.  
The unit is designed to meet ARINC 542A mounting specifications and is sealed to 

prevent moisture incursion. 
This accelerometer may be utilized as an input to flight data recorder (FDR) systems such 

as the Curtiss Wright Fortress Recorder.   
The accelerometer utilizes a 

micro-electromechanical system (

MEMS) device that 

converts gravitational and inertial forces into an analog direct-current (DC) voltage output 

for each of the three axes (vertical, longitudinal, and lateral).  The equipment includes a 

voltage regulator to provide a controlled input to the device and circuitry to scale the 

output of the device to match the range expected by the FDR.
