Digital pressure switch with 3A-approval

Baumer’s digital pressure switch series TED is now available with several 3A-approved process connections. Therefore, the hygienic measuring instrument is especially suitable for applications in the food and beverage and pharmaceutical industries.

All wetted parts are made of acid-proof stainless steel and comply with the FDA and EHEDG requirements regarding design, material and finishing. The digital pressure switch is suitable for vacuum and absolute or gauge pressure measurements up to 400 bar. The accuracy is 0.5 % of F.S.

The TED range is designed for pressure control in industrial process engineering, such as level management or control of cylinders. Based on microprocessor technology, the device can be programmed completely on-site using code protected keys without any additional tool. The pressure switch has a digital LED display and two threshold outputs (PNP transistors or galvanic isolation). The output signal can be analogue (4…20 mA) or digital (RS485 Modbus). The TED is available with many different pressure connections and in a 300° swivelling version. For applications in hazardous areas, Baumer offers its pressure switch in the intrinsically safe YTED version with ATEX-approval for zones 0, 1, and 2.
