ACT20P Bridge: Strain Gauge Signal Conditioner
15/06/2009 - Weidmuller’s NEW “ACT20P” range of signal Isolators now contains a strain gauge signal conditioner. The ACT20P-Bridge combines small size with state of the art technology providing simple programming, non interacting calibration points plus front panel or external tare function all housed in a small 22.5mm wide housing.
Using a 16 bit A/D converter, the ACT20P-Bridge will provide 4 switch selectable input ranges of 0-+/-10,20,30, & 50mV, and proportional analogue output of between 0 & 22mA with loads of <600O, and 0-+11V with loads >1k O. Accuracy is stated as better than 0.05% and has a temperature range of -40 - +70 deg C with temperature drift better that 50ppm.
Calibration is performed via front panel pushbuttons mounted under front label. Recalibration can be performed on either Zero point or Full scale without disturbing the other calibrated point.
With a fast input / output response down to 120mS ( 10-90% at 65mS) this unit will suit many weighing, force or strain gauge applications requiring accurate, high speed signal transfer either stand alone, or interfacing to a PLC/ controller providing the field supply and mV conversion.
The ACT20P-Bridge operates from a 12-60Vdc power source, with a built in precision power supply capable of driving 4 x 350 Ohm load cells with selectable 5 or 10Vdc excitation.
Our ACT20P Bridge exceeds all new CE requirements for noise immunity testing to EN61326-1:2006 ensuring accuracy and repeatability in the noisiest environments.
The ACT20P range is housed in the “NEW” ACT20 housing with a width of 22.5mm, height of 112.4mm & depth of 92.4mm. This includes removable coded connectors avoiding connection errors, and a high isolation voltage of 4kV.
The ACT20P range, will provide customers with an outstanding range of premium specified product to meet the most demanding applications whilst providing customers with further Weidmuller quality.
