Universal four-channel amplifier and power supply unit for strain measurement sensors with configurable gain and excitation voltage.

RL-S039 allows the user to connect strain-gauge sensors to any data acquisition and vibration control systems.

Every channel is equipped with a noise filter, and the amplifier provides programmable bridge offset nulling and shunt calibration.

RL-S039 protection system automatically decreases current to prevent short circuit or excitation overload.

Easily connect the amplifier to your network using USB or Ethernet, and then configure and control RL-S039 via TestUp.
