Intrinsically safe atex approved vacuum pressure sensing device with a 4-20 milliamp output for mounting in a vacuum header line for carrying waste print toner ink dust.
This intrinsically safe vacuum transmitter is configured specifically for monitoring vacuum pressure in waste toner dust extraction systems. The intrinsically safe design with ATEX approval (II 1D Ex ia IIIC T135 °C Da) ensures safe operation in potentially explosive dust environments, which is critical in toner handling applications where fine particles can pose a risk. The flush diaphragm process connection (G1/2″ with DIN 3852) minimizes particle build-up and potential blockages, ensuring consistent performance and reducing maintenance requirements.
This intrinsically safe vacuum transmitter is particularly well-suited for integration into industrial printing equipment in the following applications:
- Large format printers: Maintaining consistent ink delivery and media feed systems in wide-format printers often requires precise vacuum control. This transmitter can be integrated into the print head carriage or media handling system to ensure optimal pressure for accurate ink placement and wrinkle-free media transport.
- 3D printers: Powder bed fusion 3D printers rely on precise vacuum control to ensure a uniform powder layer distribution and prevent powder dispersion during the printing process. Integrating this transmitter into the powder bed chamber helps maintain optimal vacuum conditions for high-quality prints.
- Textile printers: In textile printing, accurate vacuum control is crucial for securing the fabric to the printing table and ensuring precise ink transfer. This transmitter can be integrated into the printing table or fabric feed system to maintain consistent vacuum pressure for high-quality prints and efficient production.
- Marking and coding printers: Industrial marking and coding systems often use vacuum to hold objects in place during the printing process. Integrating this transmitter into the printing head or object handling system ensures accurate and reliable marking on various substrates.
- PCB printers: Precise vacuum control is essential in PCB printing to secure the board during the application of solder paste or ink. This transmitter can be integrated into the printing table or stencil alignment system to maintain optimal vacuum pressure for accurate component placement and high-quality printing.
