API Coupler Proximity Switch

API Coupler Proximity Switch

The API Coupler Proximity Switch can be fitted to both our liquid and vapour API Coupler. This switch indicates when the lever is in the open and loading position. It can be fitted to API Coupler Models on various loading arms. These include the 750, 750-LR. As well as that, it can also be fitted to a Bottom Loading Arm Model 2454.

We can offer loading arms equipped with electrical components to signal many different positions or conditions. Signals can be given with the use of either electro-mechanical micro switches or proximity switches. Both types have ATEX certification.

We offer three types of proximity switches: Electrical signal for open/close 504 Model loading valve detection, Connection for the C-3659 model dry-disconnect coupling and the connection of the C-3682 model vapour return coupler.

For other loading arm accessories, please head to the bottom of our loading arm page where you can find a range valves, accessories and signal switches which are all compatible with our loading arms.

API Proximity Switches: 

Electrical signal for open/close 504 Model loading valve detection:

It signals when the loading valve gets opened by the lever. It can be realized with a EEx-d microswitch or a EEx-ia proximity switch.


Connection of the C-3659 model dry-disconnect coupling:

It is used to signal the API RP 1004 female part being connected to the respective male and the operating lever being turned in loading position. This signal is used on 740/750 or 2454-BC bottom loading arms. It is realized only with a proximity switch.
