The AT/14 is based upon the A/124 single axis voltage accelerometer and maybe considered as an alternative to the A/131 or A/134. However, the latter by virtue of being a grouping of single axis devices, are repairable and in addition the physical separation of the cables leads to visible signal axis traceability. LT17 Signal Lead: The AT/14 requires a three core screened cable. LT17 cable comprises three screened cores, anti_microphonic, wrapped in an FEP outer sheath. Overall dia is 1.7mm. Termination may comprise three separate coaxial connectors or a triaxial connector (3S).
