Signal Converter System

Advanced sensor system for use with RPM and SPM pump speed indicators

The Forum Signal Converter measures rotary table RPM and pump SPM without the use of a generator. Permanently mounted, oil-tight proximity switches perform SPM sensing. A magnetically activated probe mounted near the rotary table or next to an object that rotates in proportion to the table senses RPM. The system includes an Electronics Module, Cables, Mounting Hardware, and Sensors.

A microprocessor-based control box outputs pulse and analog signals for use by pump speed indicators and other devices, including:

  • RPM and SPM electric meters
  • Drilling recorders
  • Electronic circular recorders
  • Digital pump stoke counters
