Pressure Transmitter ED701 for Hygienic Applications

March 25, 2010. For hygienic pressure measurement, Baumer offers the electrical pressure transmitter ED701. It is especially suitable for applications in the pharmaceutical and food & beverage industries as well as in medical technology. The measuring device features high accuracy and long-term stability. It is available with several Clamp and hygienic process connections.

The piezo-resistive pressure transmitter ED701 with its stainless-steel diaphragm is based on a silicon sensor designed for high precision over a wide temperature range. This ensures that the pressure transmitter offers very high accuracy (up to 0.1 % F.S.) and excellent long-term stability (0.1 % per year). If required the zero point can be recalibrated using a simple mechanical adjustment. The measuring range can also be programmed, which allows for adaptation to the customer-specific application.

With a large range of process connections and several output signal options (4…20mA, 0…10VDC, 0…5VDC), the ED701 is suitable for a great variety of applications. In order to reduce the surface roughness, the process connections can be electro-polished. For use with aggressive media, the ED701 can be provided with a pressure connection in Hastelloy C. For applications with oxygen, the device is available with a process connection cleaned of oil and grease.

The standard oil filling is FDA-approved white oil suitable for temperatures from -10 °C up to 125 °C and used for pressure measuring in the pharmaceutical and food & beverage industry. Other available options include halocarbon oil and silicon oil, which are suitable for applications with temperatures of up to 300 °C.
