Differential pressure sensor PD41

membranepiezoresistiveanalog

The  PD40/41  differential pressure transmitters are characterized by a robust design and a significantly high overload capability. The stainless steel membrane and process connection are laser-welded, resulting in high media resistance and long-term stability. Each measuring range is temperature compensated,  which  in  combination with the piezoresistive measuring principle results in a very accurate measurement even at lowest pressures. Various electrical connection options allow easy integration and are protected against dust and water with IP 67. Features Measuring sensor with stainless steel membranes made of 1.4404 Negative pressure measuring range: up to -20 bar Accuracy ≤ 0,2% One-sided overload capability up to 250 bar Rugged industrial design Applications: Hygiene applications Viscous and pasty media Aggressive media Pressure superimposed level measurement Technical data: - Negative pressure measuring range: up to -20 bar Analog output - 4…20 mA, 2-wires - 0…10 V, 3-wires Power supply - 20 mA output: 9…30 V DC - 10 V output: 15…30 V DC Accuracy - ≤ ± 0,2 % FS @ 25 °C Long term stability - ≤ ± 0,1 % FS / Year Static pressure influence - ≤ ± 0,1 % FS/ 10 bar Hysteresis - ≤ ± 0,05 % FS Response time - 200 ms - others on request Switch-on time - < 1 s Temperature coefficient - Zero: ≤ ± 0,02 % FS / Kelvin - Span: ≤ ± 0,02 % FS / Kelvin Medium temperature - -25…120 °C Surrounding temperature - -25…85 °C Storage temperature - -40…85 °C Short-circuit resistance - Permanent Reverse polarity protection - Protection against reverse polarity, but no function
