Detailed introduction
1. Product Overview:The Rosemount 2088 gauge/absolute pressure transmitter is a commonly used model in the Rosemount pressure transmitter series. It features high reliability, long-term stability, and an easy-to-maintain design. The Rosemount 2088 pressure transmitter is suitable for almost all value-driven fields. Regardless of the application, its patented piezoresistive silicon sensor, dual chamber housing, and compact, lightweight design ensure reliable, convenient, and economical installation. By using the Rosemount 2088 gauge and absolute pressure transmitters, you can complete your work on time with quick and easy installation solutions. The Rosemount 2088 transmitter has a local operator interface (LOI) that provides an easy-to-use menu and built-in configuration buttons, allowing for on-site device commissioning without tools. This pressure transmitter is also equipped with a valve assembly and remote seals.
The Rosemount 2088 transmitter inherits the design tradition of the Rosemount 1151 model, featuring a dual chamber housing. The dual chamber housing isolates the electronic circuitry from the external environment, preventing damage to the transmitter due to environmental humidity or condensation in the conduit. Generally, sealing of the conduit is not required. Additionally, even if the sensor diaphragm is completely damaged, the dual chamber structure ensures that the terminal connections and conduit are isolated from the process.
