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.

Two 1-byte numbers (x0, 0y) are determined on the basis of this value. X0 becomes 0x (push 4 times), and ...
