Position sensor for hostile environments

July 2005 Sensors & Transducers

The Celesco PT9150 cable-extension position transducer (CET) provides reliable performance in the harshest environments - such as constant use on mining equipment. Environmentally rated to IP67, the PT9150 makes linear measurements from 1,9 m to 13,97 m with an encoder pulse output. Its ease of installation, available options and durability make it suitable for providing position feedback in large hydraulic applications.

Mining application

Superior Highwall Mining (SHM) in Chatsworth, California, USA, provides a notable application; the mine's complex boring machines required critical operating parameters be measured in extremely harsh operating conditions such as rain, mud, coal dust, and more. The PT9150 provided SHM with an 8,9 m linear measurement as each section of boring apparatus is inserted into the 'highwall'. (SHM also uses other IP67 rated Celesco products for a variety of linear and rotational measurements.)

This industrial-grade device has a full stroke range of 0-1,9 m to 0-13,97 m. The measurement is made via a stainless-steel rope that is wound on a spring-loaded spool, which then turns the shaft of a rotary encoder. For SHM, the PT9150 has a high-voltage line driver output and a resolution of 100 pulses per inch. TTL and 5 V line driver options are also available as are resolutions from 10 to 250 pulses per inch. Celesco claims to offer the largest stainless steel, nylon coated, or thermoplastic measuring cables in the industry. The PT9150 can be specified with either an aluminium or stainless steel enclosure, dependent upon the end-users environmental constraints. The flexible design allows for cable exits at the front, rear, top, or bottom.
