The Model 9004 and Model 9244 are Miniature space saving 92 x 92 x 26 mm DIN-rail mount programmable Load Cell Transmitters. Configuration and field calibration is done via a notebook or desktop PC using the user-friendly software available from our website. Complete 3-way isolation is provided between power supply, input and output.

The transmitter is designed for mV inputs from loadcells, strain gauges and strain gauge pressure transmitters. The stable bridge excitation voltage powers up to four load cells and includes sense feedback to compensate for line variations. The precision instrumentation op-amp front end circuit ensures high accuracy and stability. The adjustable digital damping feature allows for a stable output in noisy systems. The isolated analog output is configurable for industry standard voltage or current signal.

Options include one or two alarms, remote tare / zero and RS 485 output. The RS485 communications option allows interfacing to remote computers and SCADA systems using ASCIIbus or DIGIbus. Up to 32 transmitters can be linked on the same RS485 bus (using our Model 7000 comms converter).

A feature of this programmable transmitter is the calibration method. Pre-calibrated ranges can be allocated zero and full scale values and these can be adjusted on site via a notebook to allow for tare offset and test weight trim. This product meets EMC directive 89/336/EEC and Low Voltage directive 73/23/EEC.

Model 9244

This transmitter is the same as the Model 9004, but offers a 8-30 VDC isolated power supply instead of 95-265V AC/DC.
