PTS-420 series position sensor

Product Description

The PTS-420 Series Position Transmitter combines a linear position sensor with custom electronics and a rugged splashproof housing. Designed specifically for operation in demanding environments, the PTS-420 delivers a 4-20mA current loop output, making it the ideal choice for process control applications. The PTS-420 operates on a +10.5 to +28VDC loop voltage. The integral conditioning electronics convert the DC input voltage into the required AC excitation voltage for the position sensor, and demodulates the AC voltage output into a smooth 4-20mA signal. Zero and span adjustment with 10-turn potentiometers, as well as the barrier type terminal strip, are all easily accessible by removing the top cover, thereby simplifying installation and calibration. Available in a number of linear measurement ranges from 0.25 to 10 inches, the rugged construction and reliable performance of the PTS-420 satisfies the most challenging application requirements such as in power generation, rolling mills and water treatment plants. The 4-20mA current loop output is compatible with most PLCs and allows operation with long cables. Like in most of our LVDTs, the PTS-420 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 humidity, vibration and shock.
