SG-1K-KA | SG-2K-KA | SG-1K-EK | SG-2K-EK Strain Gauge Amplifiers
Single or Dual channel strain gauge amplifier as plug-in unit or euroboard
About the SG-1K-KA | SG-2K-KA | SG-1K-EK | SG-2K-EK Strain Gauge Amplifiers
The single/dual channel strain gauge amplifier in a 19“-plug-in module is designed for installation into a 19“ rack and allows supply and signal amplification of 1 or 2 strain gauge transducers. The connection of the transducers, which should have a full bridge resistance greater than 300 ohms, can be done in 4-wire technology or, by using of a long connection cable or a variable length of connection cable, in 6-wire technology. For further evaluation standard analogue outputs / channels are available. For additional measuring value presentation, option –DA offers a 3 ½ digit display/channel. The amplification of the amplifier can be adapted by an internal precision resistance. The potentiometers Z(x) (Zero) and G(x) (Gain), which are accessible via the front, allow a calibration correction for each channel.
By means of an internal dip counter / channel (-2K-), a change of the potentiometer Zx (zero) range can be achieved. To allow a zero range shift, a basic load / tare can be suppressed electrically with a resistance.
