SWISS PRIME MEASURING SINCE 1957 Ultrasonic Non-Contact Wall Thickness Transducer holders The UMAC® A8, All, A21 and A28 ultrasonic transducer holders are designed for precise, non-contact wall thickness measurements The UMAC A transducer holder was developed specifically for the medical tubing and microtubing industry. The small footprint allow an installation close to the extruder crosshead respectively in to the cooling bath nearby or the vacuum bath chamber. The perfect solution for a fast concentricity feedback and wall thickness measurement for the following main applications: • Medical tubing and microtubes • Medium sized tubes and hoses • Smaller wire and cable jackets The concentricity and wall thickness measurement of medical tubing or microtubes demands a special designed transducer holder. The new UMAC A holder series from Zumbach offers a small footprint, special product guides, mechanical features for adjusting the position within the trough; in fact all what is necessary for a smooth installation and successful measurement. • Wall thickness range: 0.05 - 12 mm (0.002 - 1.5 in.) • Option for 4 or 8 measuring points • Top opening for easy product access • Option: horizontal/vertical measuring points (flat products) • Close to zero maintenance The holders are available in two main construction designs: - Installation in the open cooling section - Height-adjustable and optionally side-adjustable - Installation in a vacuum tank cooling section - Height-adjustable and optionally side-adjustable (accessible from the outside) UMAC A transducer holders are made of durable POM material and stainless steel. The compact and robust design ensure a close to zero maintenance. The holders are submersible and each transducer socket includes a reliable water rinsing system for clearing the transducer head surface free from air bubbles or dirt. A modular design allows for customised adaptation to find needs.
