The series AP5202 is an in-line DC amplifier. It is designed to provide variable bridge excitation and signal conditioning for the following Stellar Technology products:

• Strain gauged mV/V pressure transducers
• Load cells
• Force sensors
• Reaction torque transducers

Series AP5202 Product Information

The AP5202 provides up to 10V output or 4-20 mA output with transducer signals from 10 mV to 10V. This in-line amplifier accepts both uni-polar to bi-polar input signals and can produce corresponding uni-polar and bi-polar voltage outputs. Current outputs are uni-polar. The series AP5202 provides variable transducer bridge excitation of 3V to 10V.

The following are also provided:

  • Excitation
  • Coarse gain
  • Fine gain
  • Fine zero adjustment

In addition, the capability of connecting remotely to an internal shunt calibration resistor is provided. All connections are made using screw-terminals mounted inside the AP5202’s durable aluminum enclosure. The aluminum enclosure has an IP65 ingress protection rating.
