Explosion-proof biopotential Sensors

Explosion-proof biopotential sensors are galvanically isolated, high-performance differential biological potential amplifiers optimized to measure a wide variety of biological signals such as ECG/EKG, EMG, EOG, and EEG recordings.

The biopotential sensor can be used to process biosignals from a variety of functional areas such as:

• Autonomic and sympathetic nervous system function

• Cardiovascular disease and myocardial dysfunction

• Muscle activation and fatigue

• Evoked responses

• Heart rate variability/arrhythmia

Ex Biopotential Sensors are supplied with Shielded Lead Wires and Disposable ECG Electrodes, making them suitable for human connection.

Key Features

• Connects directly through USB connection with a Windows-based laptop or desktop computer

• Electrical isolation from power-line (mains) circuitry to guarantee subject safety

• A low-noise, high-gain differential amplifier specifically designed for biological signal measurements

• Suitable for human connection

The biopotential sensor is first connected to shielded lead wires, which are then attached to the skin surface using disposable ECG electrodes

To use the biopotential sensor, connect it to the USB port or USB hub of a Windows laptop or desktop computer.

The Ex Biopotential Sensor is connected through an industrial USB 2.0 connector to an the intrinsically safe barrier Ex USB 2.0.

A green LED on the connector housing indicates the transducer is receiving power and is ready for use

The Ex Biopotential Sensor has a “hot-plug” function which allows it to be connected and disconnected without stopping, shutting down or rebooting the system.
