Model 4004 is a 4 digit (-1999 to 9999) LED Load Cell Indicator designed for mV inputs from load cells, strain gauges and strain gauge pressure transmitters.
The stable bridge excitation voltage includes sense feedback to compensate for line variations. The precision measuring front-end circuit ensures high accuracy and stability.
A digital filtering feature allows for stable displays in noisy systems. Options include programmable analog output, alarm setpoints up to 4 relays, peak or valley hold, RS232 or RS485 communications, plus more.
A feature of this programmable indicator / controller is the calibration method. The instrument may be pre-calibrated without load cell connections for zero and full scale values, and then on-site calibration may be done for deadweight offset and span calibration (single point test weight trim).
This instrument meets CE and C-Tick EMC and EMI and Low Voltage directives.
