AV Sensors is pleased to introduce the The CHT-1230 UAV Series is a rugged, temperature-compensated, millivolt-output pressure sensor engineered for high-accuracy airspeed, altitude, and environmental pressure measurement in advanced drone and UAV platforms. Built on Advanced Sensor Ceramic Hybrid Technology (CHT), the sensor integrates a high-stability silicon MEMS die with a ceramic hybrid substrate containing laser-trimmed thick-film resistors for tight calibration tolerances, excellent repeatability, and long-term reliability.
Key Performance Ranges
2 psid differential — optimized for airspeed and pitot-static sensing on fixed-wing, rotary, and VTOL drones.
15 psia absolute — ideal for altitude, cabin pressure, and environmental reference sensing in avionics systems.
Environmental & Accuracy Characteristics
Wide Compensated Temperature Range: −20 °C to +80 °C
Accuracy: ±0.25 % Full Scale (typical) over the compensated range
Response Time: < 1 ms, supporting real-time control loops and flight stabilization
Thermal Stability: minimal drift across extended mission durations
Drone System Advantages
The CHT-1230 UAV Series combines precision MEMS die performance with a rugged ceramic hybrid structure, ensuring consistent operation under rapid altitude transitions, high vibration, and wide thermal swings. Its fast response time and tight interchangeability make it ideal for UAV applications such as:
Airspeed and angle-of-attack measurement
Altitude and barometric compensation for flight control
Cabin or payload bay pressure regulation
With its robust design, precision performance, and broad environmental capability, the CHT-1230 UAV Series enables drone manufacturers to achieve more stable flight, faster control response, and lower maintenance across diverse operational conditions.
