Differential Pressure Monitoring for Large-Scale Printer Application

Ashcroft is supplying instrumentation for differential pressure monitoring in a large printer series from a leading global manufacturer.

This Use Case demonstrates how application-specific differential pressure sensing solutions helped support process reliability and print quality in a demanding OEM printing application.

Customer / Application

A leading global printer manufacturer producing large-scale printing systems. Within the printer series, reliable monitoring of air flow is essential to support machine cooling performance throughout the printing process.

Challenge

In the paper web cooling system of a large printer, friction generates a high thermal load. Continuous air flushing is required to cool the process effectively, making reliable air flow monitoring critical to machine performance.

In addition to technical performance, the customer also required a supplier capable of providing dependable deliveries and a flexible stocking concept.

Engineering Assessment

Ashcroft worked with the customer to evaluate the cooling applications within the printer series. The assessment focused on identifying instrumentation that could deliver the required measurement accuracy, long-term stability, and OEM suitability for series production.

For the cooling system, the application required a differential pressure transmitter capable of precise air flow monitoring over the long term. The evaluation also included supply requirements, with emphasis on delivery reliability and flexibility.

Solution

Ashcroft supplied a coordinated, 2-part instrumentation solution tailored to the printer manufacturer’s technical and operational requirements:

1. For air flow monitoring in the machine cooling system, Ashcroft recommended the CXLdp Differential Pressure Transducer. Its high accuracy and long-term stability made it well-suited for monitoring the continuous air flushing required to manage the thermal load generated during operation.
   
   

2. To support the customer beyond product selection, Ashcroft also worked with the manufacturer to implement an individual stocking concept designed to improve delivery reliability and flexibility.

Result

With Ashcroft’s differential pressure and temperature instrumentation in place, the printer manufacturer gained a reliable solution for monitoring a critical stage of the printing process. The CXLdp helped support effective machine cooling through accurate air flow monitoring.

In addition, Ashcroft’s ability to address delivery reliability and stocking requirements strengthened the overall solution for the customer’s series production needs.

Key takeaway

For OEM printer manufacturers, instrumentation selection must support both process performance and production requirements. Application-specific differential pressure monitoring solutions can improve cooling reliability and provide the supply flexibility needed for series manufacturing.
