The TXI7850 explosion proof I/P transducers have been approved for and utilised in natural gas operated instrumentation systems.The explosion proof evaluation of these units, using standards covering a constant fuel gas presence, ensures safe and reliable operation in the field with compressed natural gas as the supply medium.
In the US new government regulations require all pneumatic controllers at the wellhead to have a maximum consumption of 6 SCFH (Standard Cubic Feet per Hour). In other countries, carbon credits can provide economic incentives to utilise low emission products.
The TXI7850 series maximum consumption levels are 3.6 SCFH for the 3 to 15psi output range unit and 5.5 SCFH for the 6 to 30psi range unit.These rates are for natural gas as a media and applicable all the way to the highest pressure in each range.
Rotork Instruments can also provide fully approved switchboxes, positioners, solenoid valves and other actuation and severe service components to complete the automated flow control package.
