Model 14 Positive and Negative Bias Relay 14型正负偏压继电器
Part Number: M14
Designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias, Rotork Fairchild Model 14 Biasing Pneumatic Relay provides versatility in its ability to provide either positive or negative biasing in a single unit.
Rotork Fairchild Model 14偏置气动继电器专为需要输出压力为受控输入信号加上或减去固定偏压之和的应用而设计，在单个单元中提供正偏压或负偏压的能力具有多功能性。
The output of the Model 14 relay is the sum of the spring bias, set with the Range Screw, plus a pneumatic input signal. (Po = Ps + K); where Po is output pressure, Ps is signal pressure, and K is the combined spring constant.
14型继电器的输出是用量程螺钉设置的弹簧偏压加上气动输入信号的总和。（Po=Ps+K）；其中Po是输出压力，Ps是信号压力，K是组合弹簧常数。
