EST4300M Smart HART Pressure Transmitter

EST4300M Smart Pressure Transmitters

EST4300M is type of Monocrystalline Silicon Smart Pressure Transmitter, it features 4-20mA+Hart to deliver accurate (0.075%/FS) outputs for data collection and control devices.

The pressure sensitive core element adopts high performance piezoresistive monocrystalline silicon chip, which is assembled in all welded seal structure and filled with silicon oil in high vacuum.

By adopting the unique combination of several sensor systems in a single device, it allows simultaneous measurement of differential pressure and absolute pressure.

With ingress protection IP66, it commonly can be installed in industry of applications (liquid, gas, or steam) for monitoring filters and fans and level measurement of closed containers.
