Position Transmitter

The Position Transmitter, SG4-20LA, is a two wire electronic transmitter that converts resistance input into current output. When coupled to any rotary/reciprocating device, the transmitter picks up the travel of the rotary/reciprocating device and provides feedback of rotary or linear displacement via 4-20 mA signal. If this signal is supplied to the control room or to an indicating unit, such as ammeter, the current shaft position is monitored. The Position Transmitter has excellent linearity and repeatability. It is easy to install and provides an excellent price and performance ratio. The transmitter is configured to suit various shaft rotations or lifts and feedback signal is selected between 4 ? 20 mA or 20 ? 4 mA for a given movement of rotary/reciprocating device.
