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.

The Stretch/Shrinkage Monitor Model 7790 utilizes robust high pulse rate length transducers to provide precise stretch and shrinkage measurements. Its features include...
- Big figure digital display of stretch or shrinkage to 0.1 percent precision with simple keyboard entry of set point and limits for high and low LED alarm indication and internal alarm relay outputs.
- Water-tight, durable enclosure designed to withstand the harshest of mill environments.
- Select from multiple measurements - stretch, shrinkage, overfeed, underfeed. Display speed in English or metric.
- 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 output of measurement values, allowing the unit to be easily integrated into higher level control or monitoring systems.

The Stretch/Shrinkage Monitor Model 1690e Inidicating Controller includes all the inputs and outputs and all the measurement and control functions for any continuous process control application. And it has memory to store style-based control parameters for easy operator callup. And it can be expanded... add speed sensors, additional moisture channels and more. 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.
- 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.
- The standard configuration of the Model 1690e allows the connection of up to 10 Type R-90-200 or Type FM-90-200 speed speed/length tranducers. Four channels of increase/decrease control outputs can be easily expanded to eight channels.
- The Model 1690e is built from the Series 1600 PLC hardware and software components. This means that the 1690e can be converted to any other Series 1600 Indicating Controller or upgraded to one of the powerful "Combo Controllers" providing optimizaiton of multiple process parameters.
