The Model 31510 Edge Guide Sensor is designed primarily for photoelectrically sensing the lateral edge position of materials in motion, in particular web material of an opaque quality. This information is transmitted electrically to a hydraulic controller for final control action. The Model 31510 is available in two basic model options. One is used exclusively with the Dynaguide* Hydraulic Controller and has an integral transistorized amplifier. The second option can be used with the model 33130 Webguide Controller.

The Model 31520 Edge Guide Sensor is designed primarily for photoelectrically sensing the lateral edge position of materials in motion, in particular web material of an opaque quality. This information is transmitted electrically to a electro-hydraulic controller for final control action. Model 31520 is used exclusively with the Dynaguide* controller and requires a separate transistorized amplifier, Model 33130D Digital Controller.

The Model 31530 Line Guide Sensor is designed primarily for photoelectrically sensing the lateral position of a line or abrupt color contrast on web material of an opaque or transparent quality. This information is transmitted electrically to a hydraulic controller for final control action. The Model 31530 is used exclusively with the Dynaguide* Hydraulic Controller and requires a separate transistorized amplifier, the Model 33130D Digital Controller.

The Model 31560 Edge Guide Sensor is designed primarily for use on pin and clip tenter frames. The sensor detects the edge of the material and transmits an electrical signal to the Dynaguide* Electrohydraulic Controller. The hydraulic controller in turn actuates the hydraulic cylinder positioning the tenter rail.

The Model 31570 Dynaguide Centerguide Sensor includes two 6-inch Photojet centerguide sensors. These sensing heads consist of a light source and photo-conductive cells. The light source is a 6-watt tubular fluorescent lamp that operates on 115 volts AC, 50/60 Hz.

The Model 31611 Capacitance Sensor is designed for intermediate center guide applications where large width variations are encountered and accuracy requirements are not critical. This unique sensor will operate in clouded, dirty and high temperature environments, where photoelectric sensors normally cannot be used. It requires little or no maintenance.

The Model 33130D Webguide Controller eliminates the need for a separate electronic controller for various guiding applications.

The Model 21512 Pneumatic Sensor is a fixed gap nozzle, designed primarily for use with non-polarizing films such as polyethylene. This sensor detects the edge position pneumatically and transmits this information to a pneumatic-hydraulic controller.

The Model 21521 Pneumatic Sensor is a wide adjustable gap, deep throat nozzle designed primarily for use with non-polarizing films such as polyethylene. It senses the edge position pneumatically and transmits this information to a pneumatic-hydraulic controller. Many design features are included such as an integral air purge that eliminates clogging, or handwheel adjustment for fine or coarse adjustments.

The Model 21550 DYNAGUIDE Sensor detects edge position pneumatically and transmits this information to a DYNAGUIDE pneumatic-hydraulic controller which uses this information to determine the rate of correction required to maintain the edge at the desired reference position. Recovery pressure is proportional to the material position.
