Wireless Vibration, Ultrasound and Temperature Sensor Datasheet

Explore the Wireless Vibration, Ultrasound and Temperature Sensor Capabilities

Device Overview

Introducing NCD’s Wireless Vibration, Ultrasound and Temperature Sensor. Engineered for industrial predictive maintenance. They track 3-axis acceleration, vibration severity (RMS/Peak), temperature, and RPM. By capturing data up to 25.6kHz, they help detect mechanical faults (e.g., bearing wear, imbalance) before unexpected machine failures occur it also integrated ultrasound capabilities to capture high-frequency acoustic emissions.

This addition is critical because ultrasound detects the earliest stages of friction, lubrication starvation, and potential leaks long before detectable vibrations or temperature spikes occur. By combining both technologies, the sensor provides comprehensive visibility across the entire equipment degradation curve, allowing your team to identify and resolve anomalies weeks or months earlier than relying on vibration analysis alone.

Features:

  • It Helps to Detect: Misalignment, Looseness, Imbalance, Bearing wear, Gearbox wear, Lubrication.
  • Senses Vibration, Ultrasound and Temperature.
  • Analyzes On-Device: FFT, Time-Domain Data, Overall, RPM, Uptime.
  • Always-Listening Mode: Stays on to capture machines that cycle on and off.
  • Small & lightweight for ease of installation.
  • IP67 rated sealed enclosure for dust &
    moisture protection.
  • D-cell battery for long-lasting operation.
  • A versatile user-configurable sample rate for slow or fast-running machines.
  • In-Built Machine Learning optimizes power consumption.
  • Asset On-Time Calculator automatically tracks operational status.
  • Hardware Accelerator enhances vibration sampling accuracy.
  • Configurable Sample Rate – 100Hz to 25.6KHz
  • Available Wireless Transmission Frequencies – 900Mhz, 868Mhz, and 2.4Ghz
  • Supports MESH networking via DigiMesh
  • Fully open Node-RED library for configuration and data ingestion
  • No Monthly Cost.
  • Total Data Owner Ship.

Status LED

The Status LED is used to indicate errors or other sensor diagnostics.

LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.

LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.

LED blinks thrice – MCU is having issue communicating with the radio module.

Power Requirements and Expected Battery Life

Power Requirements

This device is Powered by a single D-cell (LR20) battery

While changing the batteries:

  1. Turn off the sensor
  2. Only use a new D-cell battery (obtain one from NCD, as it has a built in supercapacitor, this is not a regular battery).
  3. Make sure to align the connector in the proper orientation (this will assure you match the polarity)
  4. The battery should not be replaced in fire-risky areas
  5. Do NOT install a rechargeable battery
