High precision Melt Pressure Transducer
High precision Melt Pressure Transducer
The PT124G-112 and PT124G-112T series are high precision melt pressure transducers designed for measuring pressure and temperature in high-temperature liquid environments. They feature a special material and alloy elastic membrane to reduce temperature drift and improve accuracy. These transducers are suitable for applications in chemical and fiber equipment, polyester equipment, and plastic and rubber manufacturing.
Features
- High accuracy and excellent stability
- Stainless steel welding for durability
- Easy installation with internal 80% calibration
- Compatibility with PLC systems
Specifications
- Pressure range: 0 to 150 MPa (0 to 20000 psi)
- Output: 2mV/V; 3.33mV/V
- Accuracy: ±0.5% FS
- Max diaphragm temperature: 0 to 400°C
- Thermocouple types: J, K, E, PT100 (optional)
Installation and Maintenance
- Ensure correct machining of the mounting hole before installation.
- Use an aluminum gasket and secure the electronics housing with the provided bracket.
- Remove transducers only when the polymer is molten and clean the diaphragm immediately.
- Keep the electrical housing at room temperature to maintain accuracy and prolong lifespan.
- Avoid overloading the transducer to prevent accuracy degradation.
- Use shielded cables for wiring and ground the cable shield at one end only.
Wiring Instructions
The document provides detailed wiring diagrams for different output functions and pin configurations, ensuring proper electrical connections for optimal performance.
