| TX-120A Micro Differential Pressure Transmitter |
| keyword:Micro differential pressure transmitter, differential pressure transmitter, transmitter |

The TX-120A micro differential pressure transmitter is used to measure small differential pressures and then convert them into 4-20mA current signals for output. The TX-120A micro differential pressure transmitter series supports BRAINHART and FOUNDATION ™ Fieldbus or PROFIBSUS PA communication protocol.
