ATI Systems offers Celesco's complete family of industrial-grade cable-extension transducers. These transducers can be installed in minutes, fitted into precarious or tight areas, and they do not require perfectly parallel alignment. They offer flexibility, a small size-to-measurement ratio, and their makers say they cost less than rod or wand-type measurement devices. Most models are available for immediate shipment.
The benefits of Celesco industrial-grade cable-extension transducers
* Easy to install:
- Bolt transducer housing to fixed surface.
- Attach measuring cable to moving object.
- Make electrical connection.
* Transducer can be mounted remotely from measurement location.
* Cable can be routed over pulleys or through conduit.
* Short height, long measurement range.
* Perfect alignment not required.
* Quick delivery on most products.
Celesco transducers are available in a wide variety of configurations, both mechanically and electrically, to fit specific application requirements.
Measuring the movement and displacement of objects is easy with cable-extension position transducers. All that is needed is to mount the transducer's body to a fixed surface and attach the stainless steel cable to the movable object. As the object moves, the transducer produces an electrical signal proportional to the cable's linear extension (up to 44 m) or velocity for display, recording or feedback to a controller.
How it works
Inside the transducer's housing, a stainless steel cable is wound on a precisely machined constant diameter cylindrical spool that turns as the cable reels and unreels. To maintain cable tension, a spring is coupled to the spool. The spool is coupled to the shaft of a rotational sensor (an encoder or potentiometer). As the transducer's cable extends along with the movable object, it causes the spool and sensor shafts to rotate. The rotating shaft creates an electrical signal proportional to the cable's linear extension or velocity. The signal is in pulses per metre of cable displacement for an encoder and volts per metre of cable displacement for a potentiometer.
Electrical outputs are potentiometric voltage divider, 4-20 mA, 0-10 V and encoder pulses. The enclosures meet NEMA 4, IP65 standards, and can be supplied to meet NEMA 4X, IP67. The transducers are available in either powder-coated aluminium or bar stainless steel. The standard cable supplied is 0,92 mm diameter stainless steel stranded rope. Other diameters and materials are available. Electrical connection: either l6-pin sealed connector or 10' moulded waterproof cable.
Because the PT8600 and PT9600 modules mate with virtually any encoder, it is easy and cost-effective to meet the application's requirements. The client specifies the requirement (resolution, voltage or controller requirements). ATI's systems will mate the specific encoder needed (such as BEI, Hecon, Dynapar) with the right PT8000 or PT9000 module and calibrate the module to fit the encoder. The client then mounts the transducer's body to a fixed surface and attaches its stainless steel cable to the moving object. As it moves the cable extends and the encoder shaft spins - providing hundreds of pulses per inch.
