CTS-420 Series - Position Transmitter System * * 4-20mA 2-wire current loop operation Linear stroke ranges from 0.25 to 10 inches * Rotary version 0 to 90 * Wide operating temperature range * Compact size * Remote sensor operation up to 35 ft [10m] * MS style hermetic connector on the sensors * Rugged splash-proof electronics housing (optional) DESCRIPTION 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 potentiometers, as well as the sensor and loop supply connection terminals, are all conveniently located on the front panel for easy installation and calibration. The HCI LVDT is constructed of stainless steel and is hermetically sealed. Like in most of our LVDTs, the HCI windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high vibration and shock. 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 LVDT), HCT (2-wire LVDT transmitter), GCT (heavy-duty gage head), and RVIT 15-120i (Rotary Variable Inductance Transmitter).
