Cyclops

Cyclops detects every plunger arrival using digitally filtered sensing, optimizing your well cycle after cycle. That reliability eliminates the missed arrivals and false detections that used to disrupt cycle timing and trigger unnecessary site visits.

Cyclops plunger arrival sensor

Cyclops detects a plunger's arrival in the surface equipment using Geomagnetic Sensing Technology, reading the change in the earth's magnetic field as the plunger passes, and signals any standalone controller, RTU, or PLC to advance to the next phase of the cycle. It's built for simple, plug-and-play installation and maintenance-free operation in the field.

Up and running immediately

Plug-and-play installation means Cyclops starts delivering dependable detection right away.

More dependable cycle timing

Consistent, accurate arrival signals mean fewer disruptions and better optimization over the life of the well.

Avoid unnecessary site visits

Reliable detection means fewer trips out to investigate arrival-sensor issues or swap sensors.

Better diagnostics, right from the field

Software diagnostics identify weak arrival signals, mounting issues, or magnetic interference, giving you a clear read on the problem before you act.

Frequently asked questions

What you need to know about Cyclops.

What is Geomagnetic Sensing Technology?

Cyclops uses a magnetometer and microprocessor to read the earth's magnetic field, detecting the change created as a plunger passes rather than relying on an induced current the way older sensors do.

Will Cyclops detect a non-ferrous plunger?

Cyclops directly detects ferrous plungers. For non-ferrous plungers, the sensor can be mounted higher on the lubricator to detect movement of a ferrous spring, anvil, or trigger rod when the plunger arrives.

What's the difference between Cyclops IS and Cyclops ExP?

Both variants use the same proven sensing technology and provide the same type of arrival output. Cyclops IS is designed for intrinsically safe installations. Cyclops ExP is housed in a certified explosion-proof enclosure.

How is Cyclops powered?

Cyclops runs on 5V to 24V DC with a typical current draw of 0.77 mA, and a wireless solution is also available.

How do I see what Cyclops sees in real time?

Use the Link adapter to connect Cyclops to Vision, ETC's free device management software, to view live readings, diagnose environmental disruptions, and troubleshoot right at site in real time.
