Your reliable guard against vibration overexposure.

The HAV-Sentry system has been developed to provide real-time alerts based on vibration perceived by user’s hand, preventing overexposure and driving the formation of robust control measures.

Designed in accordance with ISO5349 & ISO8041 standards, aiming for continuous improvement.

Sleek and unobtrusive, compatible with most protection gloves.

The tough and stretchy liner glove can be used underneath or without protection gloves. Simply remove the embedded electronics to replace it.

System Components

Aegis

The Aegis represents the textile embedded sensing and control units, housing the measurement, alerting and control systems. Vibration, grip strength and hand orientation data is continuously acquired for live exposure alerts and online visualization, analysis and reporting.

Gauntlet

Aegis units come pre assembled in an ambidextrous, breathable and moisture wicking liner glove. When dirty or worn out, the glove can be washed or replaced by following the disassembly and assembly procedures.

ID Tag

A Bluetooth Low Energy tag, storing user and company identification numbers. Tags are individually assigned to each operator and used to pair with the Aegis device at the start of each shift.

Docking Station

The Aegis is connected to the Docking Station for charging, data transfer, system checks and firmware updates. Up to 5 devices can be connected simultaneously via the provided USB cables.

Dashboard

The HAV-Sentry Dashboard is a secure, cloud based, online platform designed for data visualization, analysis and risk assessment reporting. Operator specific A(8) exposure trend, grip strength, hand orientation, vibration peak and RMS amplitudes are displayed at 1Hz for each monitoring instance.

  1. The whole measurement chain needs to be checked before and after a sequence of measurements. What is the system’s method of calibration?

The accelerometer is factory calibrated and requires no further verification. Aegis device’s health, including the data acquisition chain, is checked automatically at each connection to our Docking Station.

  1. Does the unit require periodical calibration?

No. The units only get sent back under warranty conditions for major reworks or issues that cannot be resolved remotely. Firmware updates are occurring while connected to our Docking Station.

  1. Do you have a verification system for “rough handling”?

Through the data collected from sensors (accelerometer data, grip strength, hand orientation), we can estimate ”rough handling” of the device. If data acquisition is not active, we will rely on physical evidence to determine ”rough handling”.

  1. Is the data collected for each x, y, z axis and measurement duration?

Yes. The cloud-based Dashboard stores collected data under secure client accounts. Exposure information is available for visualization and download as x,y,z RMS and PEAK amplitudes, as well as exposure value A(8) and duration.

  1. Can the system display measurement overloads?

Yes, if something is wrong with the data acquisition system, damage has been incurred to the sensors, or environmental conditions are overloading the system, the Aegis will display an error alert and request connection to the docking station for further diagnostics.

  1. Is the transducer measurement range wide enough to cover the types of tools being measured?

The sensitivity of the accelerometer is +/- 32g amplitude and perceives vibration up to 2000Hz, covering the range of most power-tools.

  1. Does it start recording within 0.5 seconds of the measurement starting?

Data recording has already started when the user starts the task during which he is exposed to vibration. Continuous data recording begins after the user has logged in with the unique ID tag, at a time when the user is not being exposed yet.

  1. Does the system prevent against “fake” exposure due to normal body movements?

Data on user’s normal working pattern (walking, standing, waving, normal hand movements) is being recorded at all times after user login. However, monitoring of vibration exposure, i.e. accumulating A(8), starts only when acceleration has passed 6Hz and stops when it’s below 6Hz, thus preventing the user from faking vibration data through hand movements.

  1. Does the device have minimum enclosure specification to keep dust and water out?

Yes, the device is IP64 rated.
