CTS 420 Series

Product Description

CTS 420 Series

Position Transmitter System

Description :
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.
