ZET 410, ZET 411: small amplifiers with great capabilities! |
|
These amplifiers are designed to amplify and transmit signals to a measuring device (ZET 210 module) from resistive circuits measuring the relative deformation, twisting and bending moments, forces and other parameters, as well as to power the connected sensors.
A preamplifier is used as a signal amplifier in the processing and control systems of various devices and actuators. It is used in industry as well as laboratory and mobile research.
You can connect passive (resistive) sensors and sensors on integrated circuits (miniature accelerometers, sensors of magnetic and electric fields, etc.) to the amplifier. Select an amplification factor (fixed at 1, 10, 100 or 1,000) using the switches located on the front panel of the amplifier.
What makes the ZET 410/411 amplifier unique is that you can connect almost all the known types of sensors of physical magnitudes to electrical. The amplifier is powered from a USB bus of a PC or from a 5 V external power source, which makes it a truly multipurpose tool in designing computer measurement systems using ADC and DAC modules.
