Dynisco PT4624-5M-6/18-SIL2 Melt Pressure Transmitter 4-20mA
Product Overview
The Dynisco PT4624-5M-6/18-SIL2 is a two-wire melt-pressure transmitter with a nominal 0 to 5,000 psi range and 4-20 mA output. Its amplified current-loop signal is suitable for transmission to compatible PLC analog inputs, process controllers and monitoring equipment.
The 6/18 configuration consists of a rigid sensing stem with an approximately 18-inch flexible capillary section. The SIL2 designation identifies a safety-oriented configuration, but final SIL2 compliance depends on correct installation, system architecture, proof-test requirements and validation of the complete safety function.

Current-Loop Integration
The transmitter regulates current in a two-wire series loop. The power supply, transmitter, receiving input and loop resistance must be compatible. Only the designated signal and supply connections should be used, and polarity must be checked against the applicable wiring information.
Typical Applications
- Extrusion-line pressure monitoring
- PLC-based melt-pressure control
- Polymer filtration and screen changers
- Melt-pump protection and process supervision
- Safety-related pressure monitoring architectures
Replacement and Safety Checklist
Confirm the complete model, 5,000 psi range, 4-20 mA loop, thread, mechanical lengths, supply voltage, loop resistance, connector wiring and safety documentation. SIL2 capability of the device does not automatically certify the complete machine safety function.
Inquiry and Supply Notes
Provide the nameplate, original wiring, PLC analog-input specification and required safety documentation for review during quotation.
