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.

Features

• 4-20mA 2-wire current loop operation
• Linear or rotary position sensing
• Zero and span adjustable
• Hermetically sealed (LVDT only)
• Imperial or metric threaded core (LVDT)
• Cable assembly up to 35ft. (optional)

Applications

• 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

HCT IS Series

The HCT is a breakthrough position transmitter for use in hazardous locations. The two-wire loop configuration allows use with a single barrier and a minimum of wire or cable.
True hermetic packaging of the coil assembly and electronics provides the maximum protection against adverse environments. A 4-20 mA transmitter output is the favored configuration for process industries and power plants. Six standard ranges are available from 0 to 0.25 inches (6.35 mm), to 0 to 10 inches (250 mm). Custom scaling is available for OEM requirements. Small quantities
are generally available for same day/next day delivery.

Features

• FM Approved
• Entity Approved – with appropriate barriers
• 4-20 mA, 2-wire operation
• Measurement ranges from 0.25” to 10.0”
• Self-Contained Electronics
• Hermetically Sealed Housing
• Nonlinearity: <0.5%, 1.0% Full Range
• Calibration Certificate Supplied with all models

Applications

• Valve Position Indication
• Outdoor use with Long Cable
• Controller Roller Gap in Rolling Mills
• Process Industries
• Ideal for Noisy Environments
