Industry Challenges for High Temperature Melt Pressure
Sensors
1. High-Temperature Media Damage
In 400℃+ extreme environments, conventional melt pressure
sensors suffer from:
✔ Material Degradation – Sensor components warp or corrode under
prolonged heat exposure
✔ Data Drift – Inaccurate readings compromise product quality
✔ Shortened Lifespan – Frequent replacements increase downtime
2. Insufficient Safety Redundancy Traditional extrusion pressure transducers fail critically because they:
✖ Lack real-time overload detection
✖ Have no emergency shutdown mechanism
✖ Rely solely on software alarms (delayed response)
3. Non-Compliance with Safety Standards
Over 60% of conventional sensors can’t meet:
⚠ SIL2 Functional Safety (IEC 61508)
⚠ PLc Mechanical Safety (ISO 13849)
⚠ ATEX Explosion-Proof (for chemical environments)
Safety Relay Type High-Temperature Melt Pressure Sensors | PT190/192/193 Series
The PT190/PT192/PT193 melt pressure sensor (also called melt pressure transducer or melt pressure transmitter) is a high-precision pressure measurement device designed for high temperature applications up to 400°C.
Engineered with TI-series high-performance digital chips and compliant with SIL2 & PL’c safety standards for plastics, rubber, and chemical processing industries, this melt pressure sensor ensures reliable and safe pressure monitoring in harsh environments.
Key Features:
✔ High-Temperature Resistance – Measures pressure in liquids, gases, or pastes at temperatures up to 400°C.
✔ Safety Relay Output – Relay-based control limits enable equipment protection by triggering safety measures when pressure exceeds set thresholds.
✔ SIL2 & PL’c Compliant – Circuit design adheres to functional safety standards, ensuring fail-safe operation.
✔ Integrated Electronics – Combines a pressure sensor + signal
conditioning module for stable, buffered output.
✔ Versatile Applications – Ideal for plastics, extrusion, chemical processing, and other high-temperature industrial environments.
Product Positioning
Solving High-Temperature Pressure Control Challenges
Our safety relay-type melt pressure sensors address the three major challenges in rubber/plastic processing—precision, safety, and durability.
Leveraging innovative technology, they deliver accurate pressure control, ensuring production safety and consistent product quality.
Dual Safety Barrier Design
✔ TI High-Performance Digital Chip – Enables real-time fault
diagnostics and fail-safe control.
✔ Relay-Based Hard Protection – Hardware-level range limiting for active
risk prevention.
✔ SIL2 & PL’c Certified – Compliant with functional safety standards for
reliable operation.
Result: A dual-layer safety shield that protects equipment before failures
occur.
Precision Performance in Extreme Conditions
✔ Special Alloy Diaphragm – Withstands long-term molten material impact at 400°C.
✔ Advanced Thermal Compensation – Maintains ±0.3% FS accuracy across the full range.
✔ 3x Longer Lifespan – Engineered for durability in harsh industrial environments.
Result: Reliable, high-precision measurements—even under extreme heat and pressure.
Case Study: Overload Protection for Extruders/Injection Molding Machines
Instant Overload Response
✔ 0.1s Emergency Shutdown – When screw pressure surges, our safety
relay-type melt pressure sensor triggers an instant relay cutoff,
preventing screw fractures and mold damage.
✔ Cost Savings – Avoids single-incident losses exceeding ¥100,000 in
equipment damage and downtime.
Enhanced Equipment & Personnel Safety
Equipment Protection:
- Prevents screw breakage, mold explosions, and hydraulic system
failures caused by sudden pressure spikes.
Eliminates ¥100,000+ repair costs per incident.
Personnel Protection:
- Mitigates risks of flying debris, high-temperature melt leaks, and
equipment runaway.
Ensures operator safety by stopping hazards before they escalate.
How It Works:
Unlike passive alarms, our melt pressure sensor employs real-time pressure threshold monitoring + relay hard-contact intervention to actively break the risk chain at its origin—stopping threats before they occur.
Boosts Production Efficiency
✔ Real-Time Monitoring – Ensures stable machine operation.
✔ Minimized Downtime – Dramatically reduces overload-induced
stoppages.
✔ Higher Output – Maximizes productivity through uninterrupted, safer
production.
