About the PTS 420 Series - Position Transmitter
The PTS 420 linear position transmitter consists of a one-piece linear position sensor and transmitter electronics. Configured for use in two-wire, current loops, the PTS 420 is compatible with most process controllers. Units are available in measurement ranges from 0.25" to 10". Rugged packaging and a large barrier type terminal strip facilitates installation and screwdriver adjustments provide for ease of calibration. Designed with a rain-tight, splash-proof housing, the PTS 420 is suitable for position measurements requiring stem-type valves such as the ones frequently used in process control, power generation, and other related applications. The PTS 420 can also be used for valve position indication, roll gap control in rolling mills, and applications where long cables are required.
Applications for PTS Series
- Process Control
- Air-Handling Systems
- Power Generation
- Filtration/Water Treatment
- Steel, Aluminum, Paper, Rubber,
- and Plastic Rolling Mills
Valve Position Sensing
A PTS 420 is a two-wire current-loop position transmitter especially suited to valve position indication and other position indication in process industries.
Roll Gap Measurement
A typical application of the PTS 420 position transmitter is the measurement of the roll gap in rolling mills for steel, aluminum, and other primary metals. The same transmitter is adaptable to measuring the position of calendering rolls in paper mills, rubber plants, and plastic sheet and film manufacturing facilities.
Sluice Gate Control
The PTS 420 position transmitter can be used to measure the open height of sluice gates in sewage and waste water treatment plants. Other applications include power plant water supplies, potable water filtration plants, flood control dams, and industrial processes.
