The IPD40/41 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.
