The Radnoti 159901A transducer operates on the principle of converting picofarad capacitance changes into an amplified DC output voltage by means of a patented circuit. The transducer consists of a stiff beam suspended between two capacitor plates. This forms a differential capacitor. Using this principal, the beam can be exceptionally stiff, approaching the ideal of measuring force without motion. The linearity is within +1% with a high DC voltage output and freedom from drift.
The transducer comes with an integral short, rigid mounting handle. The transducer has a short tissue mounting rod with a groove that projects from the front. The transducer is equipped with a transparent, removable plastic shield that helps to prevent buildup of salts (i.e. corrosives) which may otherwise tend to accumulate on the transducer rod and migrate into the transducer circuit.
The transducer is supplied with an amplifier with an output which connects to any PowerLab system.
