LOW COST 12 VDC POWERED AMPLIFIER / CONDITIONER MODULE

MODEL TMO-1

The TMO-1 Module provides low cost dedicated conditioning for one bridge type load or pressure sensor. Several units can be powered from a common power supply. The TMO-1 requires a 12 VDC input source. The units provide balance and span adjustment via precision 10 turn pots. Full scale output is specified at plus or minus 8 VDC. The TMO-1 provides a floating shunt calibration circuit which applies calibration at the transducer, thereby eliminating errors due to line losses. The factory set band-width is 220 Hz. The TM0-1 can be ordered with a 2200 Hz bandwidth for dynamic applications and a 2.2 Hz or 22 Hz to improve stability in applications where noise is an issue.
