Product Description Product DescriptionThe Tissin TS900-TS905 series represents the pinnacle of explosion-proof smart valve positioner technology, engineered to deliver unparalleled precision, reliability, and safety in the most demanding industrial environments. Designed to meet rigorous international safety standards, these advanced positioners provide seamless integration with pneumatic actuators while ensuring optimal performance in potentially explosive atmospheres. At its essence, the TS900-TS905 series converts electrical control signals (typically 4-20mA) into precise pneumatic outputs, enabling accurate positioning of control valves. The positioners utilize a dual-chamber design with a torque motor and flapper/nozzle system to modulate air pressure to the actuator, ensuring rapid response and minimal hysteresis. This allows for tight control over valve stroke, whether linear or rotary, with exceptional repeatability.The intelligent electronics within the TS900-TS905 continuously monitor valve position, input signals, and operational parameters. This real-time feedback loop ensures that the valve responds accurately to control commands, even in the presence of varying process conditions or mechanical wear. The positioners also feature auto-calibration capabilities, simplifying commissioning and reducing setup time.FeaturesExplosion-Proof Design: Certified to global safety standards such as ATEX, IECEx, and UL, the TS900-TS905 series is engineered for use in Zone 1, Zone 2, Division 1, and Division 2 hazardous areas. The robust housing and intrinsically safe circuitry prevent ignition sources, making them ideal for industries handling flammable gases, vapors, or dusts.HART Communication Protocol: Equipped with HART 7 compatibility, the positioners enable bidirectional digital communication for remote configuration, diagnostics, and data logging. This allows operators to monitor valve performance, adjust parameters, and troubleshoot issues without physical access to the device.Advanced Diagnostics: The TS900-TS905 features comprehensive self-diagnostic capabilities, including valve signature analysis, actuator performance monitoring, and predictive maintenance alerts. These tools help identify potential issues before they escalate, minimizing downtime and extending equipment lifespan.

Users can configure options such as limit switches, position transmitters, and partial stroke test (PST) functionality to meet specific application requirements.High Flow Capacity: With a large pilot valve design, the TS900-TS905 series delivers high flow rates (up to 120 lpm), enabling rapid valve response even for large actuators. This ensures precise control in dynamic process environments.Wide Temperature Range: Engineered to operate in extreme temperatures from -40°C to +85°C, the positioners maintain accuracy and reliability in harsh climates and industrial settings.IP66/68 Protection: The rugged enclosure provides ingress protection against dust, water jets, and temporary submersion, ensuring long-term durability in challenging environments.Local User Interface: A user-friendly LCD display and intuitive button controls allow for on-site configuration and monitoring, eliminating the need for specialized tools.The Tissin TS900-TS905 Explosion-proof Type Smart Valve Positioner combines cutting-edge technology with robust engineering to provide precise, reliable, and safe valve control in hazardous environments. Its advanced diagnostics, modular design, and compliance with international safety standards make it the preferred choice for industries where performance and safety are non-negotiable. Whether for new installations or retrofitting existing systems, the TS900-TS905 series delivers exceptional value through enhanced process control, reduced maintenance costs, and extended equipment life.Product ParametersMODELTS905MODELTS900Input signal4~20mA DCStroke10~150mmImpedance500Ω (20mA DC)Stroke0~90oSupply pressure0.14~0.7MPaAir connectionPT1/4, NPT1/4Explosion proof typeEX ia IIC T5/T6Gauge connectionPT1/8, NPT1/8EnclosureIP66ConduitG(PF)1/2, NPT1/2Ambient Temp.
