Descrizione di prodotto
Foxboro SRD960, SRD991, SRD998 Smart Positioners
Product Overview

The Foxboro SRD960, SRD991, and SRD998 Smart Positioners are reliable digital solutions for valve automation, featuring advanced diagnostics and robust performance for rotary and linear actuators. The SRD960 provides essential control with basic diagnostics, the SRD991 adds HART communication and partial stroke testing for integrity checks, and the SRD998 offers comprehensive valve signature analysis for predictive maintenance. Built for harsh environments with IP66 protection and hazardous area certifications, these positioners support oil and gas, chemical, and power industries, ensuring safe, efficient operation and reduced downtime.

Key Features
  • Valve Signature Analysis: Detailed performance data for troubleshooting (SRD998).
  • Partial Stroke Testing: Non-disruptive valve testing to ensure operability (SRD991, SRD998).
  • Robust HART Protocol: Remote access to diagnostics and configuration (SRD991, SRD998).
  • Piezo Valve Technology: Fast response with low air consumption across all models.
  • Modular Upgrades: Easy transition from SRD960 to advanced models.
  • Travel Deviation Monitoring: Detects deviations for early fault identification.
  • Explosion-Proof Housing: Suitable for ATEX, FM, CSA certified environments.
  • Local Display: LED indicators for status and fault alerts.
  • Universal Mounting: Compatible with single and double-acting actuators.

Frequently Asked Questions
How does partial stroke testing improve safety?

It verifies valve operability without full travel, ensuring readiness for emergency shutdowns (SRD991, SRD998).

Can the SRD series be upgraded?

Yes, modular design allows easy upgrades from SRD960 to SRD991 or SRD998.

What is valve signature analysis?

It captures valve performance data to diagnose issues like friction or deadband (SRD998).

Are these positioners energy-efficient?

Yes, with low air consumption and power usage, they support sustainable operations.

How do they integrate with control systems?

HART protocol (SRD991, SRD998) enables seamless communication with DCS and PLC systems.
