Series AP50XX In-Line Amplifier from Stellar Technology

The Stellar Technology Series AP50XX in-line signal conditioner offers many options for those customers requiring high level output where application temperatures or physical size constraints do not allow having signal conditioning at the point of measurement. The AP50XX can be placed in-line anywhere between the transducer and the data acquisition system.

New DIN-Rail Amplifier for use with LVDTs

The new Series AP5104 is a convenient DIN-rail Amplifier for use with 4-, 5-, or 6-wire LVDT’s (linear variable differential transformer). The AP5104 provides regulated AC excitation with remote sensing capability for cable runs exceeding 20 feet. The AP5104 produces filtered analog outputs of ±0-5Vdc, ±0-10 Vdc, 4-20 mA, 4-12-20 mAwhich are field-selectable via the front panel.

New DIN-Rail Amplifier for use with DC Strain Gage Transducers

The new Model AP5101 is a DIN-rail mounted single channel Amplifier which provides variable excitation and signal conditioning for standard DC-excited strain gage transducers, including those for pressure, force, torque, and load. The AP5101 provides up to 10V output or 4-20 output with transducer signals from 10mV to 10V, and incorporates a DC-DC converter to insure that the output is electrically isolated from the supply. The unit accepts both uni-polar and bi-polar input signals and can produce corresponding uni-polar or bi-polar voltage outputs.

In-Line Amplifier for DC Strain Gage Transducers

The new Series AP5201 In-Line Amplifier from Stellar Technology is a low cost, easy-to-use, general purpose signal conditioner. This single- channel unit is ideal for DC-excited strain gage pressure transducers, load cells, and torque transducers.

AP5201 features an advanced analog design which solves the problem of measurement inaccuracy caused by high electromechanical noise. The AP5201 provides filtered analog output of ±5Vdc, ±10Vdc, or 4-20 mA, which is field-selectable by the user. Zero and span adjustments are made through coarse rotary switches and potentiometers. This in-line amplifier will accommodate a wide range of full-bridge DC strain gage sensors with bridge resistance for 120 to 10K Ohm.
