About the CTS 420 Series - Position Transmitter System

The CTS 420 Series is a 2-wire current loop position transmitter system especially suited to measurements in process industries. Each system consists of either an HCI Series LVDT linear position sensor or an R36AS RVDT rotary position sensor, along with an electronics module which provides a 4-20mA current loop output.

The CTS 420 operates on an unregulated 10 to 36VDC supply voltage. The electronics module provides the position sensor with the required AC voltage excitation voltage and converts the AC voltage output into a smooth 4-20mA signal. The zero and span adjustment potentiometer, as well as the sensor and loop supply connection terminals, are all conveniently located on the front panel for easy installation and calibration.

The LVDT sensor is constructed of stainless steel and is hermetically sealed. Both the LVDT and the RVDT sensors feature an integral welded-on electrical hermetic connector.
The CTS 420 is ideal for applications where the sensor must be remotely located from the electronics (up to 35 feet away) due to environmental or space considerations. In addition, inductance and capacitance levels are well below the levels set for intrinsic safety requirements. Also see our other 4-20mA position transmitter models; PTS 420 (rugged housing, IP-65), HCT-IS (Intrinsically safe, FM Approved) and GCT (heavy-duty gage head).

Applications for CTS Series

• Process industry
• Remote, oil field valve position monitoring
• Ship-board turbine throttle position control
• Paper mill head box position
• Rolling mill roller gap feedback
• Damper control on fossil fuel power plants
