Position Transmitter

SG Process Control Instruments offers a position transmitter, Model SG4-20LA. This 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 can be monitored. The position transmitter has excellent linearity and repeatability. It is easy to install and provides an excellent price and performance ratio. The transmitter can be configured to suit various shaft rotations or lifts and feedback signal can be selected between 4-20 mA or 20-4 mA for a given movement of rotary/reciprocating device. Technical specifications: operating voltage ? 24 V DC; output signal 4 to 20 mA; travel (min/max) ? 0-60?/0-90?; linearity error ? ?1%; working temperature ? up to 80?C; housing ? aluminium alloy (LM 6); protection class ? weather proof; cable gland ? PG-11; and dimensions (L x W x H) ? 90 x 75 x 130 mm.
