The ED 752 is a pressure transmitter suitable for hydrostatic depth measurement, available in 4 ... 20 mA current loop or in voltage output signal versions. This transmitter offers a very high accuracy over a wide temperature range, an excellent repeatability and very long term stability.
The piezo-resistive silicon sensor is anodic bonded on a very stable glass base, which is attached to a stainless steel construction. This assembly guarantees an excellent thermal isolation.
The sensor is isolated from the process by a stainless steel diaphragm (1.4404 / 316L) and a filling liquid. The electronics is located within the hermetically sealed transmitter housing which give the ED 752 an excellent resistance to shock and vibration. Protection class IP 68.
The electronics is a state-of-the-art signal process unit fitted with a fast micro-controller allowing the compensation of drift effects due to temperature on the sensor signal, over a wide temperature range with a fast response time. The device is protected against lightning.
The ED 752 is available with various membrane protections.
