DMC-3 (Ex-Zone 2)
Robust piezo-resistive Δp-SENSOR-TRANSMITTER industrial-grade with good long-term stability and a high overpressure safety for use in Ex-Zone 2. 3 linear Outputs: 0-10 V, 0-20 mA and 4-20 mA are part of the standard version. The TRANSMITTERs are available without or with 3-digit digital display.
Examples: air conditioning and ventilation systems, medical applications, clean room technology, filter control, level control, flow control, industry, etc.
For air conditioning or ventilation applications with the almost always present turbulences, the integrated adjustable electronic Δp-damping of the outputs and the display represents a further advantage.
