Description
The CALEX 161MK Bridgesensor is a complete signal
conditioning system on a card designed expressly for single,
half or full bridge transducers.
The 161MK consists of a high performance instrumentation
amplifier, user-adjustable active filter, high stability bridge
supply and reference regulator in a state-of-the-art hybrid
circuit. The hybrid circuit 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.
An on-board trimpot with an adjustment range from +4 to
+12VDC simplifies changing the bridge supply voltage.
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 cut-off frequency. In addition, the board allows for
mounting a quarter bridge completion resistor. Two close
tracking 20k ohm half bridge completion resistors are also
included in the hybrid circuit.
Compact, complete and convenient
Easy access to all trim adjustments
Simplifies single and half bridge applications
Eliminates additional wiring with bridge
balance trimpot
Remote sensing minimizes effects of bridge
supply lead resistance
Adjustable filter frequency
Calibration resistor for push-button calibration
