The SG1000B position monitor is designed to sense the position of both linear and rack-and-pinion driven slide gates. Housed in an explosion-proof enclosure, the SG1000B is typically used to measure the position of a process that has a repetitive linear movement, providing independent and accurate feedback via a 4-20 mA signal. To achieve this measurement the SG1000B uses a telescopic-arm to convert linear movement into an angular movement and measures the arm's angle to determine the process's linear position.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the SG1000B. It can display the 4-20 mA signal in any user units, including as a percentage between fully-closed (0%) to fully-open (100%) allowing the gate or valve to be accurately positioned when regulating the flow of a product or mixing products. The PM500 has options of two or four relays which are fully programmable and there is also a 2-channel, 16-bit 4-20 mA programmable output option for mirroring the 4-20 mA signal to a PLC.

• Works on rack and pinion or linear driven gates
• Ideal for product proportioning
• Precisely measures repetitive linear movement
• Retains monitored gate position in the event of a power loss
• Interface with PLC or use the optional PM500 Process Meter as a remote display unit
• Class I, Div I (C, D) Class II, Div I (E, F, G)

The SG1000C is housed in a compact and rugged explosion-proof, NEMA 4X enclosure, the SG1000C is an encoder-based position sensor providing a 4-20 mA output and is used to measure processes that have a repetitive single turn clockwise or counterclockwise rotary movement.

Once programmed, the SG1000C outputs a 4 mA DC signal when the encoder is at the beginning of its rotation (0 degrees) and outputs a 20 mA DC signal when the encoder is at the full turn position (359 degrees). When the encoder is at any position (between 0 degrees and 359 degrees) the SG1000C outputs a signal that is proportionally between 4 and 20 mA. Typically the SG1000C is used to sense the chute position of a rotary grain distributor enabling the end-user to very accurately monitor shaft position, ensuring accurate process control.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the SG1000C. It can display the 4-20 mA signal in any user units, including as a percentage between fully-closed (0%) to fully-open (100%) allowing the gate or valve to be accurately positioned when regulating the flow of a product or mixing products. The PM500 has options of two or four relays which are fully programmable and there is also a 2-channel, 16-bit 4-20 mA programmable output option for mirroring the 4-20 mA signal to a PLC.
