ControlAir Inc. announces the introduction of the Type 950XP Explosion-Proof I/P (Current-to-Pressure) Transducer that is approved by Canadian Standards Association (CSA) and Factory Mutual (FM) for use with natural gas. The Type 950XP approved for use with natural gas was designed as an option to deliver safe, reliable high performance for applications using sweet natural gas in the most hazardous environments.

The Type 950XP I/P Transducer converts an electrical current signal to a proportionally linear pneumatic output to actuate valves. Natural gas extraction and transport applications in remote locations often do not have access to compressed plant air for operation of pneumatic valve actuators. In this case, natural gas from the pipeline is used to supply the inlet pressure to the Type 950XP I/P Transducer that provides the output pressure used to drive control valves. The "Tapped Exhaust" option on the Type 950XP is used to connect piping which captures natural gas that vents from the unit and escorts it to a safe area, often away from the application, where it can be safely released as required. Its NEMA 4X (IP65) housing is designed for both Intrinsically Safe and Explosion-Proof operation. The Type 950XP has Factory Mutual (FM), Canadian Standards Association (CSA) and Cenelec (European) approvals for explosion-proof applications. For applications using natural gas, the Type 950XP has been approved by FM and CSA. Advanced circuitry includes electronic feedback control for superior vibration protection and highly accurate output. In addition to accuracy of 0.10%, the Type 950XP also delivers low hysteresis, and excellent repeatability. This is performance that surpasses most control system requirements. Yet because it typically consumes only .05 SCFM (0.11m3/hr) of air in operation, it not only costs less to buy, it costs less to operate as well. This is an important consideration with the high value of natural gas and the environmental effects of releasing it into the atmosphere.

The Type 950XP I/P Transducer approved for use with natural gas is ideal for natural gas extraction and transport applications such as natural gas gathering stations, compressor stations, pipeline feed, and booster stations that are in remote locations and often do not have access to compressed plant air for operation of pneumatic valve actuators.
