Pressure Regulator & Sensors for Coating Dispensing Systems

Product Specifications

Technical details and manufacturing context for Pressure Regulator & Sensors

Definition

In a Coating Dispensing System, the Pressure Regulator & Sensors are critical components responsible for maintaining precise pressure levels of coating materials during the dispensing process. The regulator adjusts pressure to match application requirements, while sensors continuously monitor pressure values, providing feedback to ensure uniform coating thickness, prevent over- or under-application, and maintain system stability across various operating conditions. This component is typically installed in the fluid line between the supply pump and the dispensing nozzle. It is designed for use with coating fluids, including paints, adhesives, and sealants, and is suitable for industrial environments where precise pressure control is essential. The unit operates within a specified pressure range (1.0–1.6 MPa) and provides a pressure setpoint accuracy of ±0.5% of full scale, ensuring consistent coating thickness. The response time is ≤50 ms, allowing for dynamic flow changes. The device requires a 24 V DC supply (24 ±10%) and outputs a 4–20 mA analog signal for integration with PLC systems. It is designed to operate in ambient temperatures from -40 to 85 °C and media temperatures from -10 to 80 °C. The ingress protection rating is IP65–IP67, making it dust-tight and protected against water jets. Wetted materials are corrosion-resistant stainless steel (316L), with process connections available in G1/4 to G1/2 thread sizes. The weight ranges from 0.8 to 1.2 kg. The device is compact for easy mounting. All specifications are reference values and must be verified with the legal manufacturer for the specific model and application.

Working Principle

The pressure regulator uses a diaphragm or piston mechanism to reduce incoming pressure to a set output level, compensating for supply fluctuations. Pressure sensors (typically piezoelectric, strain gauge, or capacitive types) convert mechanical pressure into electrical signals. These signals are processed by the system's control unit, which adjusts the regulator to maintain target pressure, creating a closed-loop control system for precise pressure management.

Frequently Asked Questions

What is the operating pressure range of this component?

The operating pressure range is 1.0–1.6 MPa. Always verify the exact range for your specific model.

What output signal does the sensor provide?

The sensor provides a 4–20 mA analog current loop output, which is standard for integration with PLC systems. This signal represents the measured pressure and is used for closed-loop control.

What are the environmental limits for operation?

The component is rated for ambient temperatures from -40 to 85 °C and media temperatures from -10 to 80 °C. It has an ingress protection rating of IP65–IP67, meaning it is dust-tight and protected against water jets.

What materials come into contact with the media?

The wetted materials are made of corrosion-resistant stainless steel (316L) as per ASTM A240. This ensures compatibility with a wide range of coating fluids. Confirm material compatibility with your specific fluid.
