The SG1000A slide gate monitor is a complete monitoring system housed in a compact and rugged explosion proof enclosure. It provides independent, accurate feedback of slide gate position to a controller (PLC) or Electro-Sensors' optional remote display.

The PM500 mounts directly to the end of the slide gate drive shaft and is easily calibrated with a single push button for setting the fully open and fully closed limit points of the gate. A second directional switch (clockwise/counterclockwise) enables the user to mount the PM500 on either side of the gate. As the drive shaft rotates, the PM500 senses the rotation and transmits a 4-20 mA signal to an external device such as a PLC or optional remote display.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the PM500. 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.

The SG1000RA slide gate monitor is designed to be an independent option for those seeking to monitor gate end-point positioning or equipment. Once end-point limits are established the SG1000RA can command equipment with built-in relay outputs. The SG1000RA is designed to work independently from a plant control system. The SG1000RA mounts directly to the end of the slide gate drive shaft and is easily calibrated with a single push-button for setting the fully open and fully closed end-point limits of the gate. The SG1000RA can be calibrated in either direction, thus reducing confusion when establishing end-point limits. As the drive shaft rotates, the SG1000RA senses rotation and if an end-point is reached it will de-energize a relay which can be used to control equipment, horns, lights or other facility alarm systems.

• Monitors a slide gate's fully-open and fully-closed end-point limit positions

• Cast aluminum explosion-proof (XP) housing 
• Class I, Div I (C, D) Class II, Div I (E, F, G)

The SG1000D valve position sensor is a complete position monitoring system housed in a compact and explosion proof enclosure. The SG1000D is an encoder-based position sensor providing a 4-20 mA output and is used to measure a rotary process such as a valve position having a clockwise or counter-clockwise rotary movement. The SG1000D works on rotary processes having a full-scale sweep as small as 15 degrees (fully-closed to fully-open), up through those having a full-scale sweep as large as 359 degrees.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the SG1000D. 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.

• Valve position feedback — 0° up to 359°
• Precisely measures valve shaft rotary movement
• Works on powered or manually driven valve shafts
• Retains valve 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 SG1000E Sub-Turn Shaft Position Monitor is a compact and explosion-proof system. It is an encoder-based position sensor that provides a 4-20 mA output and is used to measure a rotary process such as a shaft position having a clockwise or counterclockwise rotary movement. The SG1000E works on rotary processes having a full-scale sweep as small as 5.6 degrees (fully-closed to fully-open), up through those having a full-scale sweep as large as 130 degrees.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the SG1000E. 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.

• Accurate position feedback — 0° up to 130°
• Precisely measures shaft rotary movement
• Works on powered or manually driven shafts
• Non-volatile memory — retains shaft position in the event of a power loss
• Interface with PLC or use the optional PM500 Process Meter as a remote display unit

The SG1000F two-turn shaft monitor is a complete monitoring system housed in a compact and rugged explosion proof enclosure. It provides independent, accurate feedback of slide gate position to a controller (PLC) or Electro-Sensors' optional remote display.

The SG1000F mounts directly to the end of the drive shaft of a slide gate or valve and is easily calibrated with a single push-button switch for setting the application’s fully-closed/fully-open positions. As the drive shaft rotates, the SG1000F measures the rotation and outputs the 4-20 mA signal to a PLC or the Electro-Sensors optional PM500 Remote Display. The SG1000F’s output signal is 4 mA for fully-closed and 20 mA for fully-open. Most importantly, the SG1000F offers the greatest amount of accuracy for two-turn (maximum) shaft rotation applications.

The optional PM500 Process Meter can be used as a remote display and can provide the +24 VDC output power for the SG1000F. 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 shaft 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.
