SETRA WEIGHING SYSTEMS: Mass Monitor™

The Mass Monitor Series consists of a moment-insensitive load cell module and circuit board. The load cell is available in any weighing capacity from 200g to 50kg, delivering weight measurements as acute as 2ppm with a linearity of 10ppm.

The circuit includes a display connector and a bidirectional RS-232 serial data interface. The self-contained load cell can easily be installed in a scale base or other weight-supporting structure, using only three bolts.

A display board using a six digit LED is available and may be used as an integral part of the Mass Monitor package or for testing purposes only.
