The T-Chain is a long electrical cable containing temperature sensors and possibly other sensors at specific intervals. The RS 232/485 T-Chain is intended to be connected to customer-supplied power and host logger systems. T-Chain will emit calibrated measurements via RS232 or RS485. Every T-Chain is constructed on a semi-custom basis with the sensors pre-built and then positioned on the T-Chain according to customer requirements.

QUICK SENSOR DESCRIPTIONS
Temperature Sensor Nodes are molded onto the T-Chain. The thermistor is exposed to the water and located within an Inconel protective tube. This allows for fast response time, high accuracy and resolution of temperature.
Dissolved Oxygen sensors are plugged onto the T-Chain at customer specified locations. The oxygen sensor is an optode that measures lifetime-based luminescence quenching of fluorescence.
PAR sensors are plugged onto the T-Chain at customer-specified locations. These sensors use the Li-Cor LI-192SA Underwater Quantum Sensor. Pressure Sensors are plugged onto the T-Chain and are typically located at the lower end of the T-Chain. Multiple sensors can be installed on a T-Chain, but typical T-Chains only have one. Other sensors are available for the T-Chain. The Turner Designs, Cyclops-7 Sensors can be plugged onto the T-Chain.
