Combine any of NEWPORT’s process Instruments pictured here to build a complete high performance measurement and control system. NEWPORT’s complete line of controls offer industry standard options such as...

• RS-232
• RS-485
• Control/Alarm Relays

• Data Storage
• Computer Interface

The OS1551-A and OS1552-A have an exceptionally fast time constant of 10 msec (0 to 63.2%), which makes them ideal for use in fast changing processes or to capture quick temperature changes. They are compatible with any of NEWPORT’s process control instrumentation such as meters or temperature controllers. The dc system is drift free, has no moving parts and may be used in a wide variety of process applications from 0 to 1370°C (32 to 2500°F) in sub-ranges. Typical applications include: low temperature measurement in textile manufacturing, printing, paper laminating, thick plastics or measuring products heated by radiant heat sources.
