2180C 美国DT 2180C压电式压力传感器，电荷型

Design of the model 2180C utilizes a special high temperature piezoceramic material which generates a charge signal in response to sound pressure acting on the stainless steel diaphragm. The sensor is acceleration compensated to reduce the risk of spurious ambient vibration signals adding to signal output. In addition, the model 2180C features internal case ground isolation to avoid EMI/ground loop interference, as well as complete Faraday shielding of the sensing element to prevent AC noise pickup from external electrodynamic sources. This internal electrical isolation means that the sensing element is always electrically isolated from the mounting surface, and even from the diaphragm.

The model 2180C features a stainless steel construction, TNC axial connector and 1 1/8-12 mounting thread. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
