For SME-TR/TRD (Outdoor Mount) transmitter. Visit our product page to learn more about the full features.
To give guidance and highlight good practices when preparing Rheonics sensor cables with a crimp of length 8mm and terminal diameter 1mm. The terminals of the SME-TR/TRD are rated for wires of 0.2 - 1.5 mm2 i.e. AWG 24 - 16.
1. Tools and BoM list
Crimping tools are used to deform materials and create connections. To connect wires together or to other connectors, crimping is commonly used in electrical work.
A wire cutter or cable cutter is a tool that cut wires and cables in a safe manner without damaging the insulation or conductors.
A Measure Tape is a tool used to measure length.
Wire strippers are portable handheld tools used by workers, especially electricians, to remove the protective coating of electric wires for replacement or repair.
Tool used to cut wires or cables.
A durable, permanent connection can be created by joining conductive metal elements with solder. Soldering machines are essential tools for building, modifying, and repairing electronics.
Heat guns are devices that emit a jet of compressed air toward a particular point or surface.
Correct ferrule size must be selected based on the gauge of the wire, as a standard Rheonics uses ferrule with a pin length of 8mm and diameter of 1mm.
Solder wires are wires with a low melting point, used to create joints using a soldering iron.
Heat shrink tubing is a common element in most electrical installations that protects wires from moisture, dust, abrasion, and sharp objects that might otherwise damage them.

5. Cable gland installation
It is important that the metal shield from the cable is in contact with the cable gland so the electronics housing is connected to the sensor cable shield like in figure 20.

7. Properly usage of crimpers
Your crimping tool should have a nest for inserting the terminal. After inserting in the correct slot, squeeze the crimp tool firmly and release it to get a long-lasting, tight fuse.
We recommend crimping the ferrules on two sides instead of 4 sides as they work better with the terminals on the SME.
The grounding in the SME TR/TRD is achieved with the ground lug shown in figure 26.
