PT 988 Pneumatic Liquid Level Switch
WellMark’s PT988 Pneumatic Level Switch is designed for horizontal mounting in a tank or vessel through threaded or flanged pipe connections (will work in an API 2″ full coupling) and is excellent for applications where space is a factor. It can be externally caged for vessel isolation and can be used as a high or low level alarm, as well as a liquid level control. In addition, it can be switched from direct to indirect action simply by inverting the unit 180˚. The PT988 features a 3-way snap-acting pilot (0 to full output using 20-30 psi supply pressure) or order it with an optional throttling pilot (3 to 15 psi output with a 20 psi supply pressure).
