Simple Sensor Transducers Improve Learning

BIOPAC offers a wide range of high-quality, precision transducers for life science education and research data acquisition supporting human and animal experiments. These transducers connect directly to Biopac Student Lab MP3X or MP45 systems and feature Simple Sensors that help ensure correct connections, reducing equipment error and providing an enhanced classroom experience. When used with Biopac Student Lab (BSL) electrodes, software, and other accessories, these transducers are a key element in complete life science teaching or research system.

Transducers are available for a wide array of life science signals for human or animal studies, and can be purchased separately or bundled as a transducer accessory (TA) pack in order to perform additional BSL lessons.

Biopac Student Lab Simple Sensors connect directly to the “CH” analog input or output on MP36/36R, MP35, MP30, or MP45 data acquisition units.

  • There is only one way to plug Simple Sensor connectors into the MP3X or MP45, so you don’t have to worry about plugging items in upside down or into the wrong socket.
  • SSL Transducers are DSUB 9m for analog input and DSUB 9f for output and feature a 3-meter cable.
