overview：

PT20SR-3100 HART intelligent pressure transmitter is an intelligent pressure measurement product with high accuracy, high stability, multi-parameter and four and a half digits LCD display. It conforms to HART protocol. The users could manage, adjust or monitor the process variables by HART communicator, and it could also be configurated by keys on site.

The product adopts the latest application results of digital technology in the field of sensor manufacturing. It has the following characteristics: the most advanced design and manufacturing technology; digital temperature compensation and non-linearity correction technology, reliable ex-proof construction and standard signal output; high accuracy, wider range. It's suitable for precise measurement of fluid pressure.

PT20SR-3100 transmitter works in a 2-wire system and can directly replace the transmitter with 4mA~20mA DC analog output, it can communicate with ROSEMOUNT 275 or ZS-H375 hand-communicator. Electromagnetic radiation conforms to IEC801 standard.
