Non-contact Variable speed Loop control
Works on Virtually any material including paper, film or foil.
Will not mark, Scratch, dent, or tear sensitive materials.
ST-6 Standard Features
MRSH-Rev1 5" to 20’ - best for diameter measurement
MRSH-rev2 18" to 20’ - best for loop control
Adjustable gain
10’ sensor head cable
Oil tight JIC enclosure
Electrically isolated sensor
Adjustable distance zero offset
Adjustable Receiver sensitivity
Includes an exclusive circuit that allows use in applications where
bouncing strips are likely to cause false measurements.
This proprietary circuit detects false signals and rejects them
allowing SONA-TROL
to give proper take-up and Payoff smoothness regardless of strip
bounce or sway.

Optional Features
- Air pressure output
- PID output board
- RMS output board
- Sensor cables to 1000 feet
- Multiple sensors for a wide sensing area
- Adjustable measurement rate
- Limit switch outputs (up to 20 per sensor)
- Sensor Array Sequencer (up to 128 sensors)
- High Resolution sensors 3"to 24" and 5" to 48" range
- Digital or analog readout of distance, height, or diameter
of objects
- Readouts can be scaled to measure volume of liquids or
solids in tanks
- Wide range of voltage and current loop outputs
SONA-TROL Patented analog output NON CONTACT loop control is not limited to loop control applications
SONA-TROL can be used to control levels of liquids and solids in
tanks
SONA-TROL Can be used to control unwind and rewind tension
SONA-TROL Can be used to detect the presence or absence of pallets
in automated warehouses.
SONA-TROL Can measure changes as small as .010 inches
SONA-TROL Now comes in many models with a variety of standard and
optional features that allow you to configure the optimum NON
contact sensing and control system for your application
