Overview
ST800 Flange Mount Pressure Transmitters are ideal for critical applications such as natural gas custody transfer and energy and material balances, where accuracy and stability are of utmost importance. Four ranges of the transmitters are available with the following range and span:
| STF828 | -400 to 400 inH2O (-1000 to 1000 mbar) | 4 to 400 inH2O (10 to 1000 mbar) |
| STF832 | -100 to 100 psi (-7 to 7 bar) | 1 to 100 psi (0.07 to 7 bar) |
| STF82F | -400 to 400 inH2O (-1000 to 1000 mbar) | 1 to 400 inH2O (2.5 to 1000 mbar) |
| STF83F | -100 to 100 psi (-7 to 7 bar) | 1 to 100 psi (0.07 to 7 bar) |
