Airpax

Airpax is a specialized American manufacturer of precision sensing and circuit-protection components, with a product heritage built in Cambridge, Maryland and now part of Sensata Technologies. The brand is widely recognized for its magnetic and variable-reluctance speed sensors — gear-tooth pickups used for tachometry, overspeed protection, and rotational speed feedback on diesel and gas engines, turbines, and marine propulsion systems — alongside its hydraulic-magnetic circuit breakers and AP-series power switches. Airpax components serve telecommunications, marine, power generation, off-highway, military, and industrial automation markets where reliable speed detection and circuit protection are critical to safe operation. Manufacturing is carried out in ISO 9001- and ISO 14001-certified facilities, with RoHS-compliant product lines. Seven Star LLC supplies genuine Airpax speed probes and sensors to industrial and marine operators across Oman and the wider GCC, helping engineering teams maintain accurate speed monitoring and engine protection on critical rotating equipment.

Frequently Asked Questions

What sensing technology do Airpax speed probes use?

Airpax speed probes use magnetic and variable-reluctance gear-tooth sensing, generating a pulse signal as ferrous gear teeth pass the probe tip for accurate tachometry and rotational speed feedback.

Are Airpax speed sensors suitable for marine and generator applications?

Yes, Airpax sensors are widely used on marine propulsion systems, diesel generator sets, and gas engines for overspeed protection, tachometry, and governor speed feedback.

Can Airpax sensors withstand harsh industrial environments?

Airpax sensors are built for rugged duty, with rated housings and manufacturing under ISO 9001 and ISO 14001 quality systems for reliable operation in vibration, temperature extremes, and industrial contaminants.

Do Airpax speed sensors integrate with PLC and SCADA systems?

Yes, Airpax speed sensor outputs are compatible with standard PLC, governor, and SCADA speed-monitoring inputs used across industrial and marine control systems.

What else does Airpax manufacture besides speed sensors?

Airpax also manufactures hydraulic-magnetic circuit breakers and AP-series power switches used for equipment protection across industrial, military, and telecommunications applications.
