Enclosures |
|
| NEMA rated enclosures are available in
aluminum, bronze, engineered resin, or stainless steel. One to four ½” NPT, ¾” NPT, |
|
| M20 and M25 conduit entries
are available depending on model. |

Rotary to Linear Convertors |
Westlock
AccuTrak Rotary Position Monitors are available for the monitoring
of linear |
| valves via rotary to linear converters. |
 |
|
|
| Touchset™ Cams |
 |
| Cams, secured by set screws, continually
lose calibration due to vibration inherent in all pipelines. Self-locking
Touchset™ cams are fastened to a splined shaft and can be set
by hand in seconds. Since there are no set screws, the cams will
never slip out of adjustment. |

Beacon™ |
 |
An impact and corrosion resistant valve position monitor
capable of displaying exact valve position from any quadrant at distances
of up to 150 feet. Start-up
and operating personnel |
| avoid being
placed in physically awkward or dangerous situations while
attempting to ascertain valve position. |
|
|
Terminal Block |
 |
| The Accutrak™ features an elevated
pre-wired terminal block with two additional points for solenoid
valve integration. The enclosure additionally functions as a junction
box. |
|
|
| Proximity or Mechanical Sensors |
| Switch requirements will differ
with operating conditions in the industrial environment. |
 |
| Mechanical switches are less
expensive and possess the highest current
rating. Proximity sensors, encapsulated and hermetically sealed against
explosive gases and liquids, provide maximum moisture and corrosion resistance.
The reed type proximity sensor eliminates contact bounce while being
totally compatible with all host systems. |
|
|
| Agency LIstings |
| Insurance underwriters, government
authorities, engineers and plant operators regard the agency listings
and Classification Marks as evidence that the |
 |
| product
has satisfied the strictest safety requirements. The Westlock Accutrak
product family has been evaluated and listed by FM, CSA and UL as
a single assembly, rather than an arbitrary combination of unrelated
components. The Accutrak family also listed as ATEX compliant devices
by DEMKO. |
