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.

• 165 meter maximum depth

Temperature sensors are permanently molded onto the T-Chain temperature string at customer specified locations. A large number of temperature, and other sensors, can be installed on a single T-Chain. The temperature sensor thermistors are well thermally connected to the water and exhibit very rapid time response. The temperature sensors are much more than simple potted thermistors. Each sensor contains not only a thermistor, but also complex circuitry, all of which is hermetically sealed in a waterproof containment. This design gives the T-Chain very good resistance to water and extreme longevity.

The T-Chain consists of a single polyurethane sheathed cable with a Kevlar core, which maintains strength because the core is never broken. The electrical cable is specially manufactured for PME and features a very thick overall polyurethane jacket, teflon jacketed highly stranded wires, and interior Kevlar core. These features give the T-Chain its very good resistance to abrasion, tension and flexure. Only the highest quality materials and techniques are combined to give the T-Chain its very good performance in difficult situations.
