Description
The ET500 Type converts a current or voltage input signal to a linearly proportional pneumatic output pressure.
This versatile instrument is designed for control applications that require a high degree of reliability and
repeatability at an economical cost.
Principle of Operation
The ET500 Type is a force balance device in which a coil is suspended in the field of a magnet by a flexure.
Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves towards the
nozzle and creates back pressure which acts as a pilot pressure to an integral booster relay. Input signal increases
(or decreases for reverse acting) cause proportional output pressure increases.
Zero and Span are calibrated by turning adjust screws on the front face of the unit. Adjustment of the zero screw
repositions the nozzle relative to the flexure. The span adjustment is a potentiometer that controls the amount of
current through the coil.
Mounting
Unit may be pipe, panel, or bracket mounted. Mounting may be at any angle, though may require field
adjustment. High external vibration may cause output fluctuations. Mounting in a vibration-free area is
recommended.
