Description
The CALEX 160MK Bridgesensor is a complete signal
conditioning system on a card designed expressly for either
half or full bridge transducers. The 160MK consists of a high
performance instrumentation amplifier, a user adjustable
active filter, high stability bridge supply and reference regulator
in a state-of-the-art hybrid circuit, which is mounted on a PC
board mounting kit containing all of the required external
circuitry, trimpots, etc., so that only point to point wiring need
be made to the inputs, outputs and power to have a complete
signal conditioning system up and running.
The mounting kit provides coarse and fine gain adjustment
trimpots along with input and output offset adjustments, DIP
switches for setting the bridge supply output and active low
pass filter cutoff frequency.
Application of the 160MK is easy by following the detailed
applications information that is included with this data sheet
and full engineering specifications allow easy and complete
worst case analysis.
Compact, complete and convenient to use
Easy access to all trim adjustments
Half Bridge applications made easy by Internal
Completion Resistors
On card Bridge Balance Trimpot eliminates
additional wiring for Three Wire applications
Changing Bridge supply voltage is easy using
on board trimpot with adjustment range from
+4 to +10 VDC
Bridge supply lead resistance effects can be
ignored with built-in remote sensing
Filter frequency can be changed with the flick
of a DIP switch
Worst Case design is simplified with fully specified
engineering specifications. No phone calls, no
letters, it鈥檚 all right here
