This is a Total Transducer Assembly from the SCADC family of Air Data Computers. There are two similar Transducers for precision pressure measurement; the Static Transducer Assembly (STA) and the Total Transducer Assembly (TT A). Both use Solartron oscillating cylinder transducers and the inherent vibration immunity of this type of transducer makes it an ideal choice for rigorous aircraft environments.
Many thousands of these transducers have been produced for military aircraft programs over the
past decade. Transducer frequency output measurement is accurately performed on the
Transducer Interface Module (TIM). One of each device is fitted to each of the CPU-140A, CPU-141A and CPU- 142A variants, three Transducers are fitted to the to the CPU-143A and four to the CPU-152A.
