The new Cable Bellow is made of durable neoprene rubber and extends over the PT8000's cable. It prevents ice, snow, solder, and other debris from attaching to the cable and entering the transducer housing. Priced at only $99 each, the bellow makes the PT8000 a viable option for applications that typically use rod-type measurement devices in these harsh environments.

Since the PT8000 utilizes a strong, flexible cable rather than a rigid, thick rod, it has numerous advantages over rod-type measurement devices. It offers many mounting possibilities, for example. Its cable can be routed via conduit or pulleys, enabling the transducer housing to be mounted away from the application. These mounting options make the PT8000 less likely to present safety problems or to interfere with other machinery's operations. Like other members of Celesco's innovative family of cable-extension transducers, the PT8000 can be installed in minutes, function properly without perfectly parallel alignment or periodic adjustments, and fit into tight areas. Its small-size-and-low-cost-to-measurement ratio also offers remarkable flexibility and value. It retails for only half the cost of other transducers suitable for outdoors. Celesco's PT8000 transducers with the new Cable Bellow is available in measurement ranges up to 20". -more- Page 2 Celesco's New Cable Bellow Makes PT8000 ideal for harsh environments

Celesco's PT8000 Series industrial-grade position transducers have a sealed cylindrical housing to protect electrical components and an uncomplicated internal configuration, providing greater reliability and durability than other currently available transducers in the same price range. The sealed design is based on NEMA 4 standards to provide protection from environmental elements such as: dust, moisture, splashes of water, hydraulic fluid and machining oil. Its potentiometric output has virtually infinite resolution, with linearity varying from .25% for short ranges to 0.1% Full Scale for longer ranges.

Measuring the movement and displacement of objects is easy with cable-extension position transducers. A stainless steel cable is wazzu attached to the moving object, and the body of the transducer is attached to a fixed surface. As the cable extends, an electrical signal proportional to the cable's linear extension or its velocity is provided for display, recording, feedback or input to a controller. An internal spring motor maintains constant tension on the cable for retraction.

Celesco cable-extension position transducers provide voltage output by means of a precision potentiometer and are available with 4-20 mA circuitry. Many models operate in temperature ranges from 0o F to 200o F. Their resolution is essentially infinite. Celesco also offers a wide variety of measurement ranges; models are available for measuring strokes from 0" to 2" all the way through models with full stroke measurements from 0" to 1500". Celesco transducers have an accuracy of +/-0.12% full stroke for most ranges.

Celesco, headquartered in Canoga Park, California, designs, manufactures and markets a wide range of transducers and related precision instruments. The company is the world's largest supplier of cable-extension position transducers which are used to detect and measure linear position and velocity. Its other families of transducers are used for measuring rotational position and differential pressure. Celesco also manufactures thermocouple reference junctions. OEMs and end users choose Celesco transducers because of their high accuracy, resolution, and repeatability. The company, founded in 1968, is a wholly owned subsidiary of Tedea, Ltd.
