The Model 3560 Voltage Conditioner is a general-purpose instrument for conditioning, displaying, and monitoring the signal received from a DC-to-DC LVDT, potentiometer-type sensor, or other external two-wire voltage source, either floating or grounded. The input signal may also represent output from some other instrument or instrument system. ±12 V excitation is supplied for sources that require it.
Differential inputs, generous common-mode range, and excellent common-mode rejection eliminate ground-coupling errors and other problems normally associated with off-ground signal sources. Chopper-stabilized DC amplification with active low-pass filtering yields smooth and stable measurement of the true average value of the input variable, even in the face of substantial dynamic content.
Simple two-point "zero and span" calibration is provided for applications where the measured quantity is an analog of the received voltage input. For direct voltage measurements, no calibration is required.
The 3560 offers all standard 3500 Series features, including
- selectable digital smoothing
- custom 15-segment linearization
- HI/LO limit monitoring with logic I/O
- scalable analog output
- analog +peak capture
- automatic tare offset
- digital track and hold
- either single-node (RS232) or multinode network (RS485) communications
The instrument can be completely set up and operated either through the front-panel keypad or via simple mnemonic commands received from an external computer or terminal through the RS232/RS485 Interface Port.
