The ED 701 is a pressure transmitter 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
con struction. This assembly guar an ties 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 are located within the hermetically sealed transmitter housing which give the ED 701 an excellent re sis tance to
humidity, shock and vibration. Protection class, from IP 65 to IP 67 only depends on the choice of the electrical connection.

The electronics are a state-of-the-art signal processing unit fitted with a fast micro-controller allowing the compensation of drift effects due to temperature on the sensor sig nal,
