The Sensor body is made from 304 Stainless Steel and the cap is 316 Stainless Steel. The float is NBR 
(Nitrile) which is good in Oil, Diesel, Petrol, most spirits and water based products (SG: 0.7 to 1.5). 

The standard cable is Polyurethane sheathed and 6.0m in length and supplied with a 1” fitting.

 

Supplied as standard: N/C (Float Down 

 Contact Closed). 

Supplied on request, reversed float N/O (Float Down 

 Contact Open, closed on float rise).
