Incorporating the Series 3000 perfomance along with updated controls and ease of use features, the Model 3778 AC Strain Gage Panel Instrument interfaces with most manufacturer's mV/V full bridge sensors which incorporate transformer coupling of the sensor - as in the case of rotary transformer torque sensors. The 3778 delivers a stable, repeatable and accurate result with a digital display and a dynamic, selectable hi-level analog output signal for front end use with a PLC, Computer or Data Acquisition system.
The 3778 incorporates setup controls and adjustments behind the front panel for user configuration of the connected full bridge sensor - Excitation Level, Gain, Zero, Analog Filter settings, Voltage Outputs of ±5 VDC or ±10 VDC, and 4-20 mA output, Display trimming, Phase and Symmetry. The 3778, with its stable display and selectable amplified signal, includes an independent - high response - analog signal for dynamic applications.
• True Analog Operation using regulated, remote sensed excitation voltage
• + CAL, - CAL and TARE controls for ease of calibration and commanded analog "zero" capabilit y
• Selectable gain from 0.5 to 5.0 mV/V with wide zero control
• Slow, Medium and Fast amplified analog output response filter - selectable for the application
