Feature: 1. Atmospheric pressure transmitter adopts a 10‑30V wide DC voltage power supply, and a wide range of pressure of 0‑120Kpa is applicable. 2. The equipment has built in high accuracy temperature compensation, high stability, high repeatability, and long term use. 3. It supports simultaneous measurement of atmospheric pressure and temperature, and the output signal adopts 485 type with quick response. 4. Suitable for small weather stations, agricultural greenhouses, archives and other places that require atmospheric pressure monitoring and temperature measurement. 5. The atmospheric pressure sensor adopts a wall mounted shell, which can be easily fixed on the wall and has a long service life.
