Model TXI7800 High Precision I/P Pressure Transducer
Brand: Fairchild Industrial Products
Designed for use in hazardous environments, the Rotork Fairchild TXI7800 series product is an explosion proof I/P pressure transducer.
It operates under the same principles as the T7800 product; however the TXI series includes NEMA 4X explosion proof construction.
Our design isolates the electronics chamber from the pneumatic section, thereby creating a safer and longer service life product, especially for applications handling natural gas.
In the Extended Range units, the TXI7800 series will also deliver up to 0-120 psi [0-8.0 BAR], (0-800 kPa) output.
The TXI7800 series is approved for hazardous use and carries FM. CSA, ATEX and IECEx approvals.
Features- 18 available output ranges
- Accuracy as low as 0.15%
- Field selectable outputs in three pressure ranges
- Field reversible feature
- Does not contain copper-based metals
- Optional version approved for use with Natural Gas or Industrial Methane supply media
- Explosion-proof NEMA 4X, IP65, Type 4 enclosure
- Canadian Registration Numbers (CRN) certifications
- FM, CSA, ATEX and IECEx approvals
