The Fairchild Model 15 relay, available in several bias range configurations to meet a variety of output requirements, offers excellent sensitivity and high flow capacity in a small volume.
When measuring the leakage current with this setup, the voltage bias is applied to all the diodes simultaneously through the normally closed contact of each relay.
当利用这一配置测量漏流时，通过每个继电器的常闭触点同时向所有的二极管施加偏压。

This pneumatic relay provides high output flow at an output pressure that represents the input signal pressure plus a preset bias.
