In our product line we offer a couple of sensors which use a piezo-electric crystal to deliver a voltage to the PowerLab. These are the MLT1010 and MLT1012/ST Pulse Transducers, the MLT1132 Respiratory Belt Transducer and the MLA93 Tendon Hammer.
Due to their nature these devices can't be repaired.
