Introduction

The CTS-420 Series is a two-wire current loop position transmitter system specifically designed for measurements in process industries. Each system consists of an HCI Series LVDT linear position sensor or R36AS RVDT rotational position sensor, paired with an electronic module that provides a 4-20mA current loop output. The system operates on an unregulated supply voltage of 10 to 36VDC. The electronic module supplies the required AC voltage excitation to the position sensor and converts the AC voltage output into a smooth 4-20mA signal. Zero and span adjustment potentiometers, along with sensor and loop power connection terminals, are conveniently located on the front panel for easy installation and calibration. The HCI LVDT is purpose-built for the CTS-420 system, featuring stainless steel construction with sealed protection for excellent resistance to harsh environments. The CTS-420 is suitable for applications where environmental or space constraints require remote placement of the sensor from the electronics (up to 35 feet), with inductance and capacitance levels well below the threshold values specified by intrinsic safety requirements.
