Designed for reliable operation in extreme conditions, Hawkeye IS detects plunger arrivals from up to three feet away, and operates within a temperature range of -40°F to +158°F. Extensive testing has proven that even a slow-moving, non-ferrous plunger won’t slip by the eye of Hawkeye IS.
For utmost accuracy, Hawkeye IS allows the user to adjust sensitivity levels easily with a built-in seven setting dial. Lower sensitivity to eliminate false detects caused by nearby equipment or tools. Raise sensitivity to increase visibility of a plunger that doesn’t fully enter the lubricator, or to detect well movements caused when a non-ferrous plunger enters the lubricator. Hawkeye IS operates over a wide range of voltages, simplifying inventory management.
Hawkeye IS is protected by a rugged watertight aluminum enclosure filled with hardened epoxy. Built-in mounting slots support a standard hose clamp for easy and secure installation. Hawkeye IS features a ½” NPT port that enables use of either a Teck connector and armored cable, or a standard cable gland and instrumentation cable. Captive screws in the enclosure lid ensure no lost time searching for fallen screws in snow or mud.
Hawkeye IS is designed to be extremely low power. On average, Hawkeye IS draws less than 700 uA of current, fitting into all power budgets.
Hawkeye IS operates as a normally open dry contact. Simply connect the three wire interface to ground, signal, and power, and Hawkeye IS is ready to detect any plunger. Hawkeye IS uses a modern magnetic sensor chip as opposed to a traditional coil. This chip allows Hawkeye IS to detect slow-moving, or even static, plungers. Due to this magnetic sensing “eye”, the plunger does not have to fully travel past Hawkeye IS to be “seen”; allowing a wider range of mounting locations. This unique design provides additional advantages including the ability to control the sensitivity and provide a clean two second switch closure.
Hawkeye IS can be securely fixed to the lubricator or wellhead with a standard hose clamp through built-in clamp slots on the enclosure. Hawkeye IS may be left in the default sensitivity position, or adjusted to accommodate different types of plungers and lubricators, and adapt to an individual well’s conditions.
