tiltmeter

Electrolytic tiltmeters use a conductive fluid bubble and tend to have higher resolution—often sub-arc-second—making them suitable for ultra-slow movements like creep in retaining walls. MEMS units measure acceleration due to gravity and are more robust against shock and vibration, plus they cost less. If you’re monitoring dynamic events or need a wide measurement range, MEMS is the practical choice. For static, high-precision applications, electrolytic still leads.

Most of our tiltmeters output voltage (e.g., 0-5V) or 4-20mA, which interfaces with common loggers like Campbell Scientific or Datataker. We also offer RS485/Modbus versions for digital networks. Just give us your logger input specs when ordering, and we’ll configure the output accordingly.

You can use magnetic mounting pads if the beam surface is flat and unpainted, or weld-on brackets for permanent attachment. We supply brackets with mounting holes sized for M6 or M8 bolts. Leveling screws on the bracket let you zero the sensor during setup. Beam tiltmeters are often paired with our weatherproof junction boxes to simplify cable management.

For standard modifications like a different cable length or connector, we usually ship within two weeks from our factory or a regional distribution hub. Fully customized build-to-order units—say, a specific range and temperature grade—may take 4-6 weeks depending on current workload. We’ll give you a firm lead time when you place the order.

Yes, every tiltmeter leaves with a factory calibration certificate traceable to NIST. We use gravimetric tilt fixtures for verification. If you need an accredited ISO 17025 certificate, that’s available for an additional cost and slightly extends lead time.
