Calibration Instruments

The GJX-3 Vibration Calibrator combines a sine signal generator, power amplifier, standard transducer, and shaker in a single compact unit. It offers high accuracy, small size, and easy operation suitable for both laboratory and on-site use.

The GJX-5i Vibration Sensor Calibrator can calibrate various types of vibration sensors, including piezoelectric accelerometers, magnetoelectric speed sensors, and eddy current sensors. It is also suitable for calibrating vibration test instruments, vibration monitoring systems, and data acquisition systems composed of these sensors.The calibrator can internally generate standard sinusoidal signals at eight frequencies: 10, 20, 40, 80, 160, 320, 640, and 1280 Hz. Additionally, it supports a variety of signals from an external signal generator, including sine waves and swept signals with continuously adjustable frequency.The amplitude of the generated vibrations can be adjusted using a potentiometer and is displayed digitally. The GJX-5i can operate in both **vertical and horizontal directions.

The PCE-VM 31-HAWB Condition Monitoring Human Vibration Meter is designed for measuring human vibration at the workplace. The Condition Monitoring Vibration Meter can calculate hand-arm vibration measurements according to ISO 5349 and whole-body vibration measurements according to ISO 2631. Each sensor consists of a triaxial vibration meter that captures acceleration, velocity, and displacement measurements.

In addition to human vibration measurements, the vibration meter or vibration analyzer can measure the vibrations of machines. The vibration analyzer also supports TEDS, which means it can detect and identify TEDS-capable sensors automatically. Overall, the device comes with 4 independent measuring channels.

The measured data can be displayed as interval, running, or maximum RMS (MTVV), as well as estimated vibration dose value (eVDV), vector sum, peak, and maximum peak. Acceleration can also be displayed as FFT with up to 125 lines. The internal flash memory of the vibration analyzer can store up to 10,000 measurements or up to 1,000 FFTs, each with date, time, and a comment. Measured data can also be transferred to a PC via the USB 2.0 interface.

Heavy-duty side-entry constant current accelerometer with 3 isolated AC outputs (X, Y, and Z axes) and temperature. Made from robust stainless steel throughout for long-term vibration analysis in harsh environments. Internal electronics are isolated to minimize noise with increased bias voltage stability. Sealed to IP67 and includes 5-pin M12 connector and ¼"-28 UNF, M6, or M8 mounting bolt. Ideal for any application where vibration in all three spatial axes and temperature need to be measured.

General-purpose, top-entry velocity transducer with DC output. Made from robust stainless steel throughout for continuous vibration monitoring in harsh environments. Internal electronics are enclosed in a Faraday cage and isolated to minimize noise. Sealed to IP67 with industry-standard two-wire 4–20 mA output proportional to sensor range that can connect directly to PLC, DCS, and other industrial controllers. Includes 2-pin MS connector and is available with a wide range of mountings.

A must for legacy machinery and critical “it-can’t-fail” systems, the ALTA® Wireless Sensors** use an accelerometer to continuously measure vibration, speed, duration, and frequency across all three axes. Excessive vibration often indicates failing machine health, overdue maintenance, or structural damage.Monnit's vibration sensor alerts you via **text, email, or call** if an asset moves more than expected. The sensor is highly configurable, with measurement intervals as low as **one minute.

Business- and Industry-Ready Sensors

Installed within 15 minutes, these vibration sensors come in enterprise- or industrial-grade models, each offering options to suit common needs:

Enterprise options: On/off switch or line power with battery backup (and on/off switch)

Industrial options: Solar power with rechargeable battery and high-gain leaded puck

Deploy one of these vibration meters to track vital machinery or structures within your facility.

HThe WiVibX is a miniature machine monitoring device that measures triaxial vibration, bearing condition, and temperature on rotating and reciprocating plants. It communicates via a standard gateway using Bluetooth BLE for reliable connectivity and long range. The gateway interfaces to standard Ethernet and Wi-Fi networks.Acceleration and velocity overall values together with high-resolution spectra are available. The inbuilt HFE (high-frequency enveloping) function provides a clear indication of bearing condition and wear. Temperature measurement is also incorporated.

Common machine issues can be tracked such as:

•   Unbalance
•  Misalignment
• Looseness
• Early bearing wear
• Electrical problems
