TISSIN TS805 and TS905 are high-performance digital smart valve positioners developed for pneumatic linear and rotary control valves. They convert standard 4-20mA DC control signals into precise pneumatic output to adjust valve opening accurately.
Equipped with HART 7 communication, built-in self-diagnosis and PST partial stroke test function, these models support explosion-proof and stainless steel housing options. TS805 is cost-effective for general industrial sites, while TS905 is upgraded with SIL 2/3 safety certification and wider temperature range for hazardous high-demand working conditions.
Key Features
High positioning accuracy up to ±0.5%, low hysteresis ≤0.4%, stable repeatability within ±0.2% full stroke
Built-in auto-calibration function, one-button quick setup without complex manual debugging
Support HART 7 digital communication for remote parameter modification and real-time valve data monitoring
Complete self-diagnosis system with PST full/partial stroke test to predict equipment faults
Large flow pilot valve design for fast valve response and low air consumption
IP66/NEMA 4X protection grade with aluminum alloy or 316 stainless steel housing
Multiple explosion-proof certifications including ATEX, IECEx, EAC for hazardous environments
Compatible with ISO 5211 standard linear and rotary pneumatic actuators
Optional 4-20mA valve position feedback signal and dual limit switches
Wide ambient temperature range from -40℃ to +85℃

Frequently Asked Questions
Q1: What is the difference between TS805 and TS905?
A1: TS805 is economical standard model for ordinary non-safety critical workshops; TS905 adds SIL2/3 functional safety certification, wider temperature adaptability and stronger diagnostic functions for high-risk hazardous working conditions.
Q2: Can this positioner match KOSO, SUPCON and other brand control valves?
A2: Yes, it follows ISO 5211 universal mounting standard, compatible with all mainstream pneumatic linear and rotary actuators.
Q3: Does the product support remote debugging?
A3: Equipped with HART 7 protocol, users can remotely adjust parameters, read valve operation data and run PST test via HART communicator.
Q4: Is explosion-proof version available?
A4: Both TS805 and TS905 provide intrinsically safe explosion-proof models with ATEX, IECEx and EAC certificates for flammable gas environments.
Q5: What is the warranty period?
A5: We offer 2-year standard factory warranty for all TISSIN TS805 TS905 positioners.
