Mechanical Connections
Sliding‐Stem Actuator Mounting, 4210, 4211, 4212, and 4215
Use the following general procedures and figures 15, 16, 17, and 18 to mount the transmitter on sliding‐stem
actuators, standard stroke up to 105 mm (4.125 inches) travel.
Refer to figure 15 for key number locations for this example.
1. Install the transmitter on the mounting plate (key 21) with two cap screws (key 32).
