Series/Model Info

Designed for use in hazardous environments, the Fairchild TXI7800 series product is an Explosionproof I/P pressure transducer. It operates under the same principles as the T7800 product; however the TXI series includes NEMA 4X Explosionproof 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.
