Description

The DIF-USLP features a hybrid structure with a durable metal upper body that ensures a secure and stable connection to pressure instruments, paired with a corrosion-resistant plastic lower body that protects gauges and transmitters from aggressive, contaminated, or viscous media. This design makes it ideal for applications such as paint production, electroplating, wastewater treatment, and the paper industry — environments that demand strong chemical resistance and easy maintenance. Available in various flange standards and materials with optional metal or PTFE diaphragms, the DIF-USLP provides a reliable and long-lasting pressure measurement solution for chemical and environmental processing systems.
