SGT

Strain Gage Transmitter

Description

The Mode SGT, Strain Gage Transmitter, converts strain gage input to 4-20 mA or any other

standard process current or voltage output.

Typical applications include pressure transducers, load cells, and stress-strain measurements.

Output noise or ripple is less than 10 millivolts peak-to-peak, making the SGT ideal for computer

interface applications.

Complete isolation – input, output, and power input – makes it possible to apply the SGT to

virtually any input source, grounded or ungrounded, without interface problems.

The adjustable excitation source, high input impedance, complete isolation, and stability of the

SGT simplify the process of interfacing a strain gage or process control. An optional push-button

calibration feature makes it possible to increment the strain gage a fixed amount equal to a

known output for a quick system check. Errors caused by signal noise are minimized by the

120 dB (1,000,000:1) of common mode rejection.

For multichannel application, the SGT is available as a compact plug-in card module in our

standard 11-position relay rack or a 5-15 position card rack for surface mounting. An explosion-

proof housing (EX) is also available.

Features

·        Provides gage excitation. Adjustable and regulated gage excitation is provided on the SGT.

·        Complete isolation. The SGT has complete input, output, and power input isolation.

·        High input impedance. High input impedance of 10 megohms is standard to simplify interfacing.

·        Standard outputs. The unit has standard output ranges of 1-5 mA, 4-20 mA,  10-50 mA or voltage.

·        Temperature stable. The SGT has temperature stability +/-0.005%/๐F over a range of -20๐F to +180๐F.
