SIG-501 MWD Flow Simulator is designed to verify your MWD string and Sigdrill system functionality before deployment. The simulator provides pump flow on/off states via the 0 to 5V EFS system line. It also simulates pressure pulses to your MWD Sigdrill system via a 4 to 20mA current loop.

A power switch, a flow-state switch and LED indicators (power, pump/flow state and pulse line status) are integrated into the simulator. The hardware is of high-quality construction, and includes a heavy-duty Pelican case, MIL-type connectors and rugged over-molded cables. An MWD tool 5C programming cable is available separately.
