The CTS 420 is a 2-wire current loop position transmitter system especially suited to valve position indication and other position indication in process industries. The system consists of an LVDT position sensor with matching electronics to provide 4-20 mA output into 2-wire current loops. The linear position sensors are available in six ranges covering 0- 0.25″ to 0-10.0″. The CTS 420 System is particularly well suited for sensing valve position of stem-type valves because the sensor can be coupled directly to the valve’s operating shaft for exceptional reliability and accuracy. Of special interest to the process industries is that the system’s inductance and capacitance are well below the levels set for intrinsic safety requirements. The LVDT sensor is constructed of stainless steel and is hermetically sealed and uses a non-contacting movable core, so there is nothing to wear out. The electronics portion of the CTS 420 system is contained on a 3 x 5 inch circuit board which can be installed up to 25 feet from the sensor. All external connections and adjustment controls are mounted directly on the board. The electronics board is also available with an optional splash-proof enclosure.
