Single-Axis Accelerometers That Fit Your Monitoring Setup
Accelerometer（single-axis）
Most geotechnical monitoring projects don't need a sensor that does everything. A single-axis accelerometer often gets the job done without extra noise or cost. At Kingmach, we keep a practical range of these sensors because we know that for tasks like bridge pier tilt or retaining wall vibration, one direction is usually the one that matters. Our catalog covers standard models, but if your project has unusual mounting or output requirements, we can adapt the design. With distribution partners across several continents and an engineering team that actually responds to technical questions, we're set up to support integrators and field engineers from pilot studies through long-term deployment.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach's single-axis accelerometers are built for the kind of repetitive, long-duration measurements that civil and mining engineers rely on. The sensing element is a MEMS chip housed in a rugged stainless steel or aluminum case, with standard output options including 4-20 mA, 0-5 V, or RS485. Sensing range choices usually span from ±2 g to ±200 g, so you can pick a model that matches your expected motion level—micro-vibrations near a heritage structure or higher shocks from blasting. The IP67 rating on most models keeps them dry in outdoor trenches or wet boreholes. A standard cable length of 5 meters is included, but we'll ship with longer cables if you ask. Temperature compensation from -20 °C to +80 °C keeps the zero offset drift under 0.5 mg/°C, which matters when you're comparing data across seasons. In the field, people often use these accelerometers on structural beams, around dam abutments, or in slope inclinometer arrays. Because we handle everything from PCB assembly to final calibration in-house, we can provide small custom runs—like a different connector, a higher excitation voltage tolerance, or a specific mounting bracket—without delays that would throw off a project timeline. For larger orders, we maintain a 2-4 week lead time and ship via air freight with tracking.

FAQ
Common technical questions
How do I choose the right measurement range for a single-axis accelerometer?
Think about the maximum g-level you expect plus some safety margin. For ambient vibration on buildings, ±2 g or ±5 g is typical. For rotating machinery or construction impacts, you might need ±50 g or ±100 g. Kingmach can supply any of these ranges, and if you're not sure, our engineers can look at your application and suggest a starting point.
Can I get these accelerometers with a different output signal than what's on your datasheet?
Yes, that's a common customization. While our standard outputs are 4-20 mA, 0-5 V, and RS485, we can adjust the analog output scaling or add digital protocols if you have a specific data logger requirement. Just let your sales contact know before ordering.
What kind of mounting options do you provide for single-axis installations?
The thread on the base is typically M6 or 1/4-28 UNF, and we include a set screw for flat surfaces. For curved surfaces like a pipe, we offer optional magnetic bases or strap clamps. If you're bonding the sensor directly, we recommend a flat, clean surface and a cyanoacrylate adhesive.
How do these accelerometers hold up in long-term outdoor use?
Our stainless steel units with IP67 seals have been running in field installations for years without moisture ingress. The main thing to watch is the cable entry—keep the cable loop so water doesn't track down. We also pot the internal electronics to cut vibration-induced fatigue on solder joints.
Do you provide calibration certificates with the sensors?
Yes, each sensor ships with a traceable calibration certificate showing sensitivity, frequency response, and linearity. We also offer annual recalibration services if you send the unit back to us.
