ITS 300 Series Position Monitoring Switch
Description
ITS position monitoring switch is used for the valve and actuators which rotates 90 degree quarter turn. The first function of ITS is to provide the visual indication of the current position of the valve and actuator. Dome indicator unit shows current position by color indication.
Secondly ITS provide electrical signal at the fully open or closed position by activating mechanical switches (SPDT, SPST), Proximity sensors and other magnetic sensors which independently makes function. Switches vary in a wide range and construction to meet customer’s requirement.
