| 摘要 |
The invention relates to a process and a device for the operational test of a membrane-resistance and/or piezo- resistive pressure detector. Detectors installed in explosion-endangered installations must be examined for operability using the process and device. By means of the process in accordance with the invention equalized compressed air or compressed gas is regulated to a desired value and then the pressure detector is loaded with this test pressure. Desired value and test pressure are displayed separately, whereby the associated switch point can be read optically and/or acoustically. The devices required for carrying out the process are accommodated in a carrying case.
