Cable-powered vibration sensor

Vibration & recording specifications

Configure recordings remotely from the dashboard. The current sensor captures X, Y and Z together and also measures internal temperature.

Vibration range

Selectable ±2, ±4, ±8 or ±16 g

Sampling rate

12–3,200 samples/s

Recording length

32–8,192 samples per axis

Channels

X, Y and Z vibration; internal temperature

FFT frequency range

Up to 1,600 Hz at 3,200 samples/s; the measured response also depends on the sensor and mounting

Analysis on the M4

Time waveforms, FFT spectra, waterfall plots and sample export

Processing options

Acceleration in g or velocity in mm/s; averaging and high-pass filtering

At 3,200 samples/s, 8,192 samples cover 2.56 seconds with 0.391 Hz FFT bin spacing. At 400 samples/s, the same sample count covers 20.48 seconds with 0.049 Hz bin spacing. Sampling rate is distinct from usable measurement bandwidth.

Peak & Instant capture

Peak mode

With external power, repeated recordings are evaluated during each interval. The retained recording is downloaded at the interval end if it qualifies for the configured threshold.

Selection channel

Peak mode evaluates Z-axis vibration activity and retains the corresponding X, Y and Z recording.

Instant mode

A recording is made at the scheduled time. Optional retries can add attempts when the threshold is not met.

Between recordings

On DC power, the radio stays awake. After an Instant recording is downloaded, measurement waits in standby for the next request. Peak mode repeats recordings through the interval.

Manual recording

REC requests an instant recording.

Download threshold

Select None to download recordings without threshold filtering. A threshold can exclude recordings made while the machine is idle.

Peak mode retains a recording from the interval, rather than a continuous history of every capture. Set the interval and recording duration around the machine’s operating cycle.

Power & mounting

Supply

24 V DC nominal; 6–60 V DC input

Current

10 mA maximum

Connector

3-pole M8 for DC power; signal contact unused

Backup

One CR2032 coin cell for short-term fallback; the sensor sleeps between wake-ups while external power is absent

Mounting

M3 screw, magnetic or selected epoxy mounting

Power cable

Matching M8 cable, with 5 m and 10 m options

Antenna clearance

Keep the 80 mm area shown in the mounting drawing clear of metal

Mount rigidly to the measurement surface and secure the cable so it does not load the sensor. Follow the installation document for connector wiring, antenna clearance and sealing.

Wireless data connection

Measurement data travels over the iQunet sub-GHz radio network. The M4 receives recordings through a compatible iQunet radio interface and stores them locally. Select the matching radio band for the sensor and network hardware.

8A radio

868 MHz band

9A radio

915 MHz band

Network hardware

M4 with compatible iQunet radio interface; existing installations may use the original USB Base Station

Radio coverage

Typically up to 50 m in plant conditions; layout and placement affect coverage

Coverage extension

Compatible iQunet Repeater

M4 data access

Browser analysis, OPC UA, MQTT, GraphQL and OpenAI MCP

IVIB161410-24V-PWR · 8A / 9A · D1636 specification

Measurements

Three-axis vibration and temperature

Dimensions

57 × 47 × 14 mm, excluding the M8 connector

Weight

40 g

Enclosure

IP68

Operating temperature

−20 to +85 °C

Power

24 V DC nominal; 6–60 V DC input

Backup cell

One replaceable CR2032

Earlier catalogue versions list 35 g, IP65 and −20 to +70 °C. Use the documentation for the installed model; the original product release specifies server software 1.3.1 or later.
