Shrinkage Monitor Model 7770
Shrinkage Monitor Model 7770
Digital Indicating Controller

The Shrinkage Monitor Model 7770 is the latest technical upgrade to Strandberg's forty years experience in on-line automatic shrinkage control for compressive shrinking ranges. Overshrinking causes huge production losses each month. Key in the shrinkage set point and let the 7770 add production back to your bottom line. Features include...

  • New Length Sensors Type R90-200HSA, with low mass, high surface area sensing wheels, resolution one thousandth of one meter, located at machine entry and exit.
  • Digital step correction control algorithm with increase and decrease relay outputs for connection to machine speed control.
  • Bright red LED digital display readable from 10 meters. Keyboard and 2-line LCD display for entry of shrinkage set point, high and low tolerances, and control parameters.
  • Analog output of measurement values for connection to recorders, PLCs, and higher level systems.
  • Optimizes production yield and minimizes residual shrinkage variation. Use Strandberg Moisture Monitors to measure and control moisture at rubber belt entry and measure at machine exit to ensure optimal shinkage control performance.

Shrink-Rite Model 1605e
Shrink-Rite Model 1605e
Comprehensive Process Control for Finishing and Shrinking

The Shrink-Rite Indicating Controller Model 1605e provides comprehensive monitoring and control for finishing ranges and compressive shrinkage machines. Simple operator callup of style number loads specific set points and control limits for key shrinking paramters. The system design is modular such that the optimum combination of sensors and control devices can be included with the key objective to minimize variation in residual shrinkage. Its features include...

  • Microprocessor-based PLC system including membrane keyboard and 1/4-VGA LCD display with non-volative memory for processing parameters, multi-channel input and output cards, RS-232 port for report generation and RS-485 port for network connection.
  • Typical measurements and controls include residual moisture at rubber belt entry and machine exit, finishing range stretch/shrinkage, shrinkage, pick count at machine entry and exit, width control at finishing zone exit, width monitoring at machine exit, and measurement of changes in pick count at shrinking zone entry compared with standard value.
  • Dynamic adjustment of shrinkage applied in the shrinking zone to compensate for variations in potential shrinkage introduced in prior processes.
  • Residual moisture measurement provided by the Strandberg Moisture-to-Computer Interface Type 1035E. Strandberg offers moisture calibration services for ISO-9000 compliance.
  • The optional Series 2700 Operator Console package provides a touchscreen monitor with PC for unlimited storage of style processing data, historical data archiving and report generation.

Laser Pick/Course Counter  Model 7762A
Laser Pick/Course Counter Model 7762A
Digital Indicator

The Laser Pick/Course Counter Model 7762A utilizes advanced laser optics to precisely measure the linear density of moving fabric in terms of pick or course counts. Its features include...

  • Big figure digital display of pick or course count to 0.1 counts per inch or centimeter precision with simple keyboard entry of set point and limits for high and low LED alarm indication.
  • Water-tight, durable enclosure designed to withstand the harshest of mill environments.
  • Laser Sensor Type 6307A is hermetically sealed and nitrogen gas filled to maintain long-term performance of internal components.
  • High speed digital signal processing analyzes each thread used the the measurement calculation. The laser beam angle is continously checked for optimum position to maintain accuracy.
  • Utilizes Type R-90-200 surface-driven speed/length transducers with cast, stainless steel wheels to maintain accuracy for long-term use in contact with abrasive materials and in applications with significant temperature shifts.
  • Optionally use Type FM-90-200 shaft-driven speed/length transducers for applications in which material contact is not feasable. Simply enter a ratio easily calculated from roll diameter and sprocket sizes.
  • Industry standard, scalable 4-20mA outputs or pick/course count and speed values, allowing the unit to be easily integrated into higher level control or monitoring systems. Optionally, the current set point value can be substituted for the speed output so that the higher level system can compare actual versus target values.
