Performance

The ASC TS-91V1 and TS-91V5 are uniaxial MEMS capacitive tilt sensors engineered for precise inclination measurements in demanding applications. They use highly sensitive low-g MEMS accelerometers to detect static acceleration caused by gravity. With a resolution of 0.005° and long-term bias stability of 0.1° per year, both sensors ensure reliable performance over extended periods .

They provide a nominal full-scale output of ±2 V for ±90° tilt, with linear response within ±15°. Operating from a wide supply voltage (+6 to +36 VDC), they consume just 2 mA per axis, making them highly energy efficient. Both models withstand shocks up to 5,000 g and provide stable operation from −40 °C to +120 °C.

Usage conditions

The TS-91V1 features a lightweight anodized aluminium housing (IP67), ideal for compact or weight-sensitive systems. The TS-91V5 offers stainless steel housing with IP68 protection, making it robust enough for marine, construction, or other harsh outdoor environments.

Applications

• Crane safety systems
• Building and construction machinery
• Solar tracking systems
• Ship navigation and posture measurement
• Bridge monitoring
• Track alignment and railway maintenance
• Wheel alignment systems
• Truck chassis levelling
• Machine tool angle positioning

Advantages of choosing these sensors

The ASC TS-91V1 and TS-91V5 offer engineers flexibility: a lightweight aluminium version for compact and mobile setups, and a rugged stainless steel version for maximum durability. Both deliver high precision, long-term stability, and reliable analog output.
