Static Strain Digital Indicator PSD-704

Introduction of the strain amplifier to amplify the signal from strain gage, transmit and indicate it, and the strain generator to calibrate the equipment connected with strain gage applied transducer, such as load cell, ressure sensor, etc.

Features

・Indicator for strain gage or strain gage applied transducer
・Check strain gage based transducers in mV/V.
・Measure I/O resistance of strain gage based transducers. Insulation resistance between main body and each cable wire is also available.
・Applied RS-232C interface as a standard.
