Extending Temperature Sensors (SN100)

The temperature sensor (SN100) comes with a standard 50' (15m) cable. You can extend this cable up to a maximum of 150' (45m) total which is a 100' extension (30m). 

To extend the temperature sensor you will need two things:

1. Appropriately rated 2 conductor cable
2. Outdoor / Waterproof method for splicing cable
   1. Waterproof Connector Kit
   2. Waterproof Splice Kit

Extension Methods

To extend the existing wire sensor, there are two methods.

1. Pre-made Extension with Connectors

The first is to contact Altrac for an extension cable or extension kit. We have pre-made lengths of cable with waterproof connectors. Also we offer an extension kit which includes 500' of wire with connectors and crimpers to make your extension any custom length. 

2. Waterproof Splice

You can use waterproof splice connectors to extend the propane cable. Whatever you use should be waterproof. DO NOT USE UNSEALED BUTT CONNECTORS!

Step 1: Cut the cable anywhere between the probe tip and the connector. If you are pulling the wire through a tube/pipe it usually makes sense to cut close to one of the two ends.

Step 2: Connect the wires color to color on both sides of the extension

Step 3: Connect the drain wire on both sides of the extension

Splice Recommendations

1. DryConn Connectors (silicone filled)

2. Solder and heat shrink
