The Spirax Sarco PN600 is a robust and versatile electronic pressure transmitter designed for accurate and reliable pressure measurement in industrial steam, water, and air systems. The specific model you’ve referenced, 12K0001, with a range of -1 to 4 bar and a 625 output, is a common configuration for monitoring both vacuum and positive pressure in steam systems and other industrial processes.
Key Features and Specifications
Based on your code PN600 BAR RANGE -1 TO 4 12K0001 625, here is a breakdown of its specifications:
-
Product Line: Spirax Sarco PN600 Series Pressure Transmitter
-
Model Code: 12K0001
-
Pressure Range: -1 to 4 bar gauge
-
This means it can measure vacuum (suction) down to -1 bar and positive pressure up to 4 bar. This is ideal for applications where the process can fluctuate between vacuum and positive pressure.
-
-
Output Signal: 625
-
In Spirax Sarco’s coding, “625” typically refers to a 4-20 mA analog output signal. This is the industry-standard two-wire signal for process control, proportional to the measured pressure.
-
-
Electrical Connection: Typically a 2-pin M12 connector or a conduit entry, suitable for industrial environments.
-
Process Connection: Usually a G½” or ½” NPT female thread for easy installation into pipework.
-
Wetted Parts: Manufactured from stainless steel, ensuring excellent corrosion resistance and compatibility with steam, water, and compressed air.
-
Accuracy: High accuracy, typically around ±0.5% of full-scale span.
-
Display: Many PN600 models come with an optional local LCD indicator for easy on-site reading.
