About the A750-150 & C750-150 Series 

– Black Diamond single-axis inclinometers for maximum precision in harsh environments

The A750-150 and C750-150 are part of the Black Diamond Tilt Sensor Line and represent the highest-precision models in this family. Both are rugged, high-performance single-axis tilt sensors engineered for top performance in extreme conditions. Their fluid-damped mechanism provides excellent noise and disturbance rejection under shock and vibration, ensuring a very stable output characteristic.

A750-150 vs. C750-150 (quick difference)

• A750-150: focused on 0–5 V output with a +9 to +18 VDC supply.
• C750-150: adds a 4–20 mA option (0–5 V also possible), ideal for long cable runs and industrial integration; +20 to +30 VDC supply.

Both series are available with a 6-pin connector, pin terminals, or flying leads. An internal temperature sensor is optional, and both are RoHS compliant.

Key benefits at a glance

• Single-axis precision tilt measurement with 1 µrad resolution/threshold
• Fluid damping for stable readings in vibration-prone applications
• Tilt ranges (examples): ±1°, ±3°, ±14.5°, ±30°, ±60°, ±90°
• Rugged & outdoor-ready: IP66, operating −40 to +80 °C, 1500 g shock (depending on model/spec)

Typical applications

Ideal for precise tilt and attitude monitoring, such as:

• High-precision geotechnical monitoring
• Oil & gas (e.g., riser tilt monitoring)
• Bridge sag & sway monitoring
• Dam monitoring
• Structural analysis
• Platform leveling

Selection recommendation

• Choose A750-150 if you prefer a classic 0–5 V analog output and a lower supply voltage.
• Choose C750-150 if you need 4–20 mA (or 0–5 V) for robust industrial wiring and long cable distances.

Black Diamond Series

Black Diamond tilt sensors are cost-effective, high-precision inclinometers, developed to provide higher accuracy than comparable MEMS devices. They are intended for geotechnical monitoring applications including bridge deflection and movement, deflection measurement, platform leveling, and structural analysis.
