Cooper Instruments DCM433 Specifications
DCM 433/437 - CURRENT BRIDGE AMPLIFIERS
he DCM series provides adjustable excitation voltage and
signal amplification for any strain gage transducer. The
T
DCM 433/437 provide on-board low pass filtering to eliminate noise
problems commonly associated with strain gage load cell signal
conditioners. The DCM 433/437 provides a 4-20 mA output.

BRIDGE AMPLIFIER
DCM 460/465 - VOLTAGE BRIDGE AMPLIFIERS
he DCM series provides adjustable excitation voltage and
signal amplification for any strain gage transducer. The sig-
T
nal gain may be adjusted from 40 to 1000 making it the ideal unit for
application where a digital readout or serial link is not required. The DCM
460 and 465 both provide up to a 0-10 Vdc output, while the DCM 460
offers greater bandwidth for faster settling time.
