IntroductIon
The MVD 100 measuring Amplifier is designed to control forces, loads, pressures, etc. in connection
with analog sensors, predominantly with DMA transmitters. After conditioning the actual value
signal, the device is digitally assisted by a processor (MSP 430/TI). A total of 3 switching thresholds,
which include hysteresis, switching performance, and pick-up delay, can be programmed and
generated.

descrIptIon
Low drift precision operational amplifiers are used to amplify the sensor voltage to a level which can
be processed by the processor’s own A/D converter. The digitalized actual value is then compared
with several set values. Switching signals are triggered if the actual value coincides with, or exceeds
any of these set values. The relevant set values are entered via a keyboard with LCD display which
can be plugged into the amplifier’s PCB. This control unit may remain connected or be removed
from the amplifier after programming since it does not affect the amplifier’s function.
