摘要： A wireless communication system and its test method capable of executing a test of the wireless communication apparatus from a remote place by using a terminal generally used in wireless communication systems are implemented with a low-cost configuration and a simple procedure. A terminal obtained by installing a test AP on a general terminal that is used in general wireless communication systems and that can execute APs via a communication network is placed in a coverage area of a wireless communication apparatus. A maintenance center for the wireless communication system activates the terminal. The terminal executes the test AP and conducts communication with the maintenance center by using control signals and test signals for testing wireless communication system. A test is executed by measuring an actual communication state of the wireless communication system.

摘要： A pressure sensing transmitter comprises a housing, a sensor base, a ceramic sensor, thick film resistor members, an isolation diaphragm, and an isolation fluid. A sensing surface contacting with the isolation fluid is formed with a spherical surface form, the thick film resistor members are sintered on a sintering surface of an opposite side against the sensing surface projection area, and a test fluid flow is isolated from the sensing mechanism by a metal diaphragm so that a process fluid pressure is transferred indirectly to the sensing element. According to the invention, since each of the thick film resistor members 14A and 14B are sintered at both the interior and exterior of the sensing surface projection area 13C, a sintering area can be made larger than that of a conventional one, so that a larger output can be maintained without losing any characteristic of the thick film resistor member. This arrangement also provides a higher degree of precision, long life stability, as well as increased safety and reliability.
