Characteristics of the Positioner

Model Code

Operating principle

When the input signal is applied to the input chamber (1a), the flapper moves in the arrow A direction around the fulcrum plate spring (2). This movement causes the flapper (3) to be separated from the nozzle (4) the pressure of the nozzle back-pressure chamber (5) to decrease, the balance with the pressure chamber (6) to be lost, and the relay spool (7) to push the port A (8a) to open the air-intake valve seat. At the same time, in port B (8b), the air-intake valve seat of the relay spool (7) is closed and the exhaust valve is opened. Supply pressure is fed from the OUT1. to the right cylinder chamber (14a) and from the OUT2. to the left cylinder chamber (14b) and finally vented to the atmosphere via the exhaust port (13) to lower the stem (15). This movement is transferred to the B lever (16b), A  lever (16a), cam (18), zero arm (20) and range arm (21) to extend the feed-back spring (12) and move until the spring tensile strength balances with the output of the input chamber. Accordingly, a change in the opening of the stem (15) in proportion to the input signal pressure is obtained. In balanced conditions at the point indicated by the signal, the respective air-intake valve seat and exhaust valve seat of the OUT1. and OUT2. are returned to the neutral position. In the conditions where loads are not applied to the right and left cylinder chambers, the pressure is set at the balance pressure (approx. 75% of supply pressure).

Characteristics of the Positioner

Model Code

Operating principle

When the torque motor (1E) receives input power, its armature (2Eb) pivots in the direction of arrow A around the fulcrum plate spring (3). This pivot separates the flapper (5) from the nozzle (4), reducing the pressure in the nozzle’s back-pressure chamber (12) and upsetting its balance with the pressure chamber (11). Consequently, the relay spool (13) actuates, opening port A (15a), which connects the lower cylinder pressure chamber (17e) to the exhaust port (9) and causes the stem (18) to descend. This action is transmitted through the feedback lever (19), cam lever (20), range arm (23), and zero arm (26), extending the feedback spring (7) and continuing until the spring’s tensile strength equals the torque motor’s (1E) absorption power. Thus, the stem (18) moves in proportion to the input signal.
