Gauge Carrier
TORNADO gauge carriers are designed for long term reliability with pressure testable metal to metal seals and can be configured for single, dual and Y-splice gauges. Materials are available to meet any type of downhole environment, such as 4140, 4150, 13CrL80, SN95, 1925 or Super 13 Chrome. The carrier is machined from one solid block of material and complies with API 5CT guidelines.
Permanent Downhole Cable
The standard cable that TORNADO uses is suitable for high pressure, high temperature environments. The cable has ¼-inch outside diameter steel outer cable and can be either SS316 or Alloy825. Other features of this cable include:
Max. pressure up to 20,000 PSI
Temperature rating up to 150˚C or 200˚C based on material and environment
Tensile rating >1 tonne typical
Conductor 18AWG stranded wire

Cable Protectors
Cable protectors are used across the tubing joints to protect the cable from mechanical damage. Customers can choose from iron cast or cannon style protectors. Iron cast protectors are recommended due to their exceptional longitudinal and rotational slippage resistance (Longitudinal > 5 tonnes, Rotational > 3 tonnes), and crush resistance (̴ 4 tonnes).

Cable Head & Cable Splice
The cable head and cable splice have multiple metal to metal seals and are pressure testable in the field. The cable head has rotation and vibration protection built in. The specifications are:
• ¼” Tube cable with max OD 0.875”
• SS316 / Inconel 718
• Pressure Rating 25,000 PSI
• Temperature Rating 0 to 200 °C

Wellhead Outlet
The wellhead outlet is a device that is used to connect downhole cable to the surface data acquisition system. Its primary purpose is to provide wellhead pressure control upon cable termination. It has metal to metal seals, accepts one conductor and can accommodate most flanged connections.
TORNADO Software
SmartWatcher software allows for system configuration and diagnostics. It has full Modbus support and displays data in real time as needed. Data can also be downloaded from an SD card and flash memory.
