Run the cable attached to the transformer unit in through the access hole that is equipped with the cable clamp and terminate it as specified on the interconnection diagram.

2.2.4. Completion and Inspection.

After the electrical connections have been completed, slide any excess slack back into the conduits so that the installed wiring is not in contact with the components mounted on the analyzer chassis.

Remove the three foam strips that are taped to the inside of the analyzer door and use them to stuff the conduit openings. It is important that these openings be as well sealed as possible.

Check to see that the temperature control printed circuit board, and all vacuumtubesarefirmlyseated intheirrespectivesockets.

Close and latch the control panel. There should be no further need to have access to the interior of the analyzer. All controls and adjustments are arranged sothattheycanbemanipulatedwithoutdisturbingthedelicatetemperature equilibriumoftheinstrumentinterior.

Note #1: Itisabsolutelynecessarythatallconnectionsandcomponents in the gas control system ahead of the measuring cell be leak

free. Toward that end TAI has tested the integral sampling system under pressure with a sensitive leak detector and certifiesthattheanalyzerisleakfree.

Note #2: Use no solder connections in the system. Soldering fluxes outgas into the sample lines and produce erratic output readings. Acid type soldering fluxes actually attack and permanently change the characteristics of the detector cell measuring elements.

Note #3: All sample system tubing should be new and clean. Many gases and vapors are absorbed by dirt or oxide coatings on tubing walls. These gases and vapors are released as the ambient temperature rises. Because of the high sensitivity of the analyzer, this absorption-desorption phenomenon can

212R specifications

Teledyne 212R is a state-of-the-art underwater acoustic modem designed for robust communication in various marine environments. This advanced device is based on established principles of underwater acoustics and modern digital signal processing technologies, making it an optimal choice for applications ranging from oceanography to underwater robotics.

One of the standout features of the Teledyne 212R is its high data transmission capabilities, allowing for reliable communication at distances of up to several kilometers depending on environmental conditions. The modem supports various data rates, enabling flexible adaptation to the needs of different applications. This versatility makes it suitable for both low-bandwidth telemetry and high-data applications, such as video streaming from underwater drones.

The Teledyne 212R employs advanced modulation schemes that enhance its performance in challenging conditions. These modulation techniques, combined with sophisticated error correction algorithms, ensure the integrity of data transmission even in noisy environments. This resilience is crucial as it enables the modem to maintain communication in the presence of marine life, background noise, and varying temperatures.

Another remarkable characteristic of the Teledyne 212R is its compact and rugged design. Built to withstand harsh marine conditions, the modem is encapsulated in a pressure-resistant housing, making it suitable for deep-sea operations. Its durability ensures longevity and reliability, reducing the need for frequent maintenance or replacement, which can be costly in remote underwater settings.

Moreover, the modem features an array of integrated sensors that allow for real-time environmental monitoring. This capability can be pivotal for research organizations studying marine ecosystems or for oil and gas companies conducting underwater surveys. The ability to collect and transmit environmental data alongside operational data streamlines data-gathering efforts.

Ease of integration is another key aspect of the Teledyne 212R. It is compatible with a multitude of existing marine technologies and communication protocols, allowing for seamless deployment in diverse systems. This adaptability is essential for users requiring collaborative operations across multiple platforms, such as Autonomous Underwater Vehicles (AUVs) and remotely operated vehicles (ROVs).

In summary, the Teledyne 212R combines high-performance data transmission, advanced modulation techniques, rugged design, and environmental monitoring capabilities. This makes it an essential tool for anyone engaged in underwater research, exploration, or resource management, establishing it as a go-to choice in the field of underwater communication.
