ABSTRACT:
A valve position transmitter which is comprised of an indicator assembly having a base with an aperture located thereon, an adjusting ring placed on the base about the aperture, an indicator member capable of identifying the operational position of a remote valve said indicator member being positioned on the adjusting ring, and a transparent cover placed about said indicator and secured to the base of the indicator assembly. Said valve position transmitter also comprising a shaft assembly extending from the point where it may be coupled to a valve through the aperture in the base of the indicator assembly to a point where it engages with the indicator member such that any rotation of the shaft assembly is sensed by said indicator member and some display with respect to such rotation is made. The valve position transmitter may also be comprised of a switch box assembly comprising a housing wherein are located switches for detecting rotation in the shaft member, said switches being electrically connected to a terminal strip and in turn said terminal strip being connected to remote peripheral devices. Said valve position transmitter may also be comprised of a split shaft assembly wherein upper and lower shaft members are provided for such that a peripheral device may be permanently coupled to said upper shaft member and it may be removed along with the upper shaft member to allow for easy field servicing of the remainder of the device.
