Product Description:
YT-1000 Series (Electro-Pneumatic Positioners)
Base Models: YT-1000L (Linear) and YT-1000R (Rotary).
Description: These devices convert a 4-20mA DC electrical control signal into a proportional pneumatic output pressure. They drive pneumatic actuators to precisely position control valves as required by the control system.
YT-1200 Series (Pneumatic Positioners)
Base Models: YT-1200L (Linear) and YT-1200R (Rotary).
Description: These are force-balance type positioners that receive a 3-15 psi (0.02-0.1 MPa) pneumatic control signal and provide a proportional amplified air output for use in purely pneumatic control loops.
Models with Position Transmitter (+SPTM)
Specific Models: YT-1000L+SPTM and YT-1000R+SPTM.
Description: These are electro-pneumatic positioners from the YT-1000 series integrated with a valve position transmitter. In addition to controlling the valve, they provide real-time feedback of the valve's stem position (typically as a 4-20mA signal) to the control system for remote monitoring.
Features:
High Reliability & Stability:
Precision mechanical design ensures long-term operational stability and excellent linearity.
Robust Environmental Adaptation:
High Vibration Resistance: Unique anti-vibration design allows stable operation within a 5-200Hz frequency range without resonance.
High Protection Rating: Features an IP66 enclosure rating, providing effective protection against dust ingress and powerful water jets.
Explosion-Proof Certification: The YT-1000 series typically carries Exia II BT6 explosion-proof certification, making it suitable for hazardous areas.
Easy Installation & Setup:
Flexible Configuration: Easy conversion between direct/reverse action and single/double acting modes.
Universal Mounting: Comes with various mounting kits and accessories to fit most pneumatic actuator brands.
Adjustable Performance:
Adjustable Damping: Equipped with an adjustable damping mechanism (needle valve) to optimize valve response and prevent hunting by controlling the output airflow rate.
Split Ranging: Supports input signal split ranging to meet specific process control requirements.
