HT DH Telemetry – 32mm – Internal PSU

Description

The NSE Wireline Telemetry System is used for communication via wireline or powerline. The system consists of two main components: topside unit and one or more downhole modems.

The NSE Wireline Telemetry System operates as a transparent link between the topside user interface/applications and the electronics located in the downhole tool. Serial commands sent from a computer to the topside modem are modulated and superimposed on the power cable. This signal is demodulated and converted back to conventional serial commands (TTL or CANBus) in the downhole modem.

The modems are designed to communicate over wire- or powerlines. Even if monoconductor wireline is the main use, the versatility of the system has made it popular in other applications such as coiled tubing and subsea backup communication system.

NSE Wireline Telemetry Systems are deployed worldwide and cover all applications from power tools, such as tractor and strokers, to low power sensor and data acquisition tools. The reliability of the link allows data transfer in very noisy conditions over difficult cables and the system will optimize data rates for the given setup.

The system requires very little user interaction. In most cases the modems will autotune to the correct gain and frequency settings for a cable. During operation the system is continuously adapting to the conditions on the line in order to optimize the signal to noise ratio.

The system is addressable so several down hole modems can communicate with one topside modem and has a broad input voltage range.
