The current methods used for in-place diagnostics and calibration verification of low differential pressure transmitters in high-precision or critical airflow systems are very labor intensive and can lead to problems. Agency regulations typically require monitoring and certified calibration on a regular basis. With conventional units, you must periodically remove the pressure tubing and transmitter wires to check calibration against traceable standards.

Based on the Si-Glas, a silicon-on-glass capacitive sensor, the Ashcroft DXLdp is the first of a new generation of low ...
