190 Position Transmitter

The Model 190 Position Transmitter is a device that uses movement of the valve stem to provide a 4-20mA analog signal proportional to the valve position. The signal increases as the valve opens. It consists of an adaptor threaded into the center port of the valve bonnet, a rod threaded into the main valve stem, a stem seal, and the transmitter unit. The position transmitter is linear, linked to the indicator rod with with a stainless steel cable.The unit requires a user-furnished VDC power supply (typically 24VDC). It may be installed on virtually any OCV control valve, and can be done so without any disassembly of the valve itself.

  • Provides 4-20mA signal, proportional to valve position.
  • Installed without disassembly of valve.
  • Enclosure is weatherproof NEMA 4 (IP – 6S)
