Minimizes the effects of supply pressure variation.
Minimizes downstream pressure droop under flow conditions.
Isolates the diaphragm from the main flow to eliminate hunting and buzzing.
Easy to install in the field
Certification for use in all Canadian territories and provinces.
Designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias, Fairchild's Model 14 Biasing Pneumatic Relay provides versatility in its ability to provide either positive or negative biasing in a single unit. 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.
