Tissin TS900 Smart Valve Positioner HART Communication Explosion Proof Chemical Oil Gas Pipeline

The Tissin TS900 Series Smart Valve Positioner is a premium-grade industrial automation device engineered for precise valve stroke control in response to a 4-20mA input signal from a control panel, DCS, or calibrator. As the flagship model in the Tissin positioner lineup, the TS900 combines advanced digital control technology with robust flameproof Ex db IIC construction, delivering exceptional reliability in the most demanding and hazardous process environments.

Available in both linear and rotary configurations, the TS900 accommodates stroke ranges from 10 to 150 mm for linear valves and 0 to 90 degrees for rotary actuators. Its intuitive LCD display with four-button local control interface allows operators to perform quick auto-calibration, partial stroke testing, and mode switching directly on the device without external tools. Optional HART communication enables seamless integration into modern smart plant architectures for remote monitoring and diagnostics.

Built with a rugged aluminum die-cast housing and rated IP66, the TS900 Series withstands harsh industrial conditions including high vibration, extreme temperatures, and corrosive atmospheres. Whether deployed in chemical processing, oil and gas production, power generation, or water treatment, the TS900 delivers the precision, safety, and long-term reliability that critical process applications demand.

• Liquefied natural gas (LNG) processing and storage terminals
• Water and wastewater treatment systems for municipal, industrial, and desalination applications
• Pharmaceutical manufacturing with stringent process accuracy and cleanroom requirements
• Steel and metal processing mills with high-temperature and heavy-vibration environments
• Pulp and paper production lines requiring corrosion-resistant automation components
• Marine and offshore platforms with salt-spray exposure and extreme weather conditions
• Hydrogen production and handling facilities where flameproof certification is essential
• Food and beverage processing with hygienic process control demands
• General industrial automation where precise valve positioning and safety compliance are critical

A: The TS900 is the flagship model with flameproof Ex db IIC certification, making it suitable for Zone 1 hazardous areas. The TS800 features intrinsically safe Ex ia IIC protection for Zone 0 and Zone 1 applications. The TS900 also has a heavier, more robust construction at 7.7 lbs compared to 4.8 lbs for the TS800, offering enhanced durability in extreme environments.

A: The TS900 is available in linear configuration for stroke ranges of 10 to 150 mm and rotary configuration for 0 to 90 degree rotation. Both share identical electronic and pneumatic specifications.

A: Yes, HART communication is available as an optional feature for digital bidirectional communication, enabling remote configuration, diagnostics, and predictive maintenance integration within smart plant systems.

A: Yes, the TS900 Series is SIL 2 certified, making it suitable for safety instrumented systems (SIS) where partial stroke testing and alarm functions are required for functional safety compliance.

A: The TS900 requires instrument air meeting ISO 8573-1 Class 3 quality standards. This ensures clean, dry air supply that prevents internal contamination and maintains consistent positioning accuracy over the product lifetime.

A: Yes. The IP66 and NEMA 4X rated enclosure provides complete protection against dust ingress and powerful water jets, making the TS900 suitable for outdoor installation in most environmental conditions. The wide ambient temperature range of -40°C to 85°C accommodates extreme climate zones.

A: Optional accessories include 4-20mA transmitter feedback, 2 end-of-travel mechanical limit switches, HART communication module, mounting brackets for various actuator types, and a range of spare parts including gauge assemblies, pilot valves, and feedback modules.

A: Ex db (flameproof) protection contains any internal explosion within the enclosure and prevents flame propagation to the external atmosphere. This allows higher power circuits and is preferred for installations where intrinsic safety barriers are impractical. Ex ia limits energy to prevent ignition altogether, suitable for Zone 0 areas but with power limitations on connected circuits.
