Overview
ST800 Differential Pressure Transmitters are ideal for critical process loops and high-value applications such as custody transfer, and energy and material balances. Four models are available with the following ranges:
| STD810 | -10 to 10 inH2O | -25 to 25 mbar |
| STD815 | -100 to 100 inH2O | -249 to 249 mbar |
| STD820 | -400 to 400 inH2O | -996 to 996 mbar |
| STD830 | -100 to 100 psi | -6.9 to 6.9 bar |
| STD870 | -3,000 to 3,000 psi | -207 to 207 bar |
