Explosion-Proof Current-to-Pressure Transducer Is Vibration and Position Insensitive

April 27, 2009
ControlAir launches its Type-595XP Explosion-Proof Current-to-Pressure I/P Transducer

ControlAir Inc. announces the introduction of the Type-595XP Explosion-Proof Current-to-Pressure I/P Transducer. This current-to-pressure transducer is small, light weigh and less sensitive to shock, vibration and position changes than other I/P’s. The unit’s low power consumption, along with it’s worldwide agency approval for intrinsic safety, makes it well suited for hazardous environments in remote locations.

The conversion technology utilizing open loop control provides a high level of regulation accuracy and repeatability for the operation of actuated valves. A low mass control circuit provides reliable linear output in difficult applications at an economical cost. The Type-595XP can mount in any position and is stable in high vibration environments.

The Type-595XP holds agency approvals from Factory Mutual (FM) and Canadian Standards Association (CSA) as intrinsically safe and explosion-proof. It is also compliant with the ATEX directive 94/9/EC for equipment intended for use in potentially explosive atmospheres.

The unit is designed for applications where power is at a premium, such as booster stations in remote locations that often do not have access to compressed plant air for operation of pneumatic valve actuators. Other applications include valve control where the environment can be hazardous.
