Descriptions
Hengesbach is a company from Deutschland. For more than 50 years Hengesbach develops, manufactures and distributes innovative measuring technology for applications in production processes where functionality, reliability and accuracy of the instruments are of highest priority even under extreme process conditions.
Pressure Transmitter DME 11 Series
The Hengesbach Type DME 11 pressure transmitter with ceramic membrane is a cost-efficient pressure transmitter for standard applications, for example in the energy field. The measuring pressure acts directly on a ceramic membrane that deforms when pressure is applied. The electronic system integrated into the pressure transmitter housing converts the signal generated by the DMS connector on the ceramic membrane into a standard electrical output signal 0…20 mA, 4…20mA or 0…10V DC.
Features:
- output signal 0–20 mA, 3-wire, 4-20 mA, 2-wire or 0-10V DC, 3-wire
- pressure-measuring ranges from 0-1 or -1-0 to 0-400 bar
- for standard applications, e.g. in the energy field
