This series of smart pressure and differential pressure transmitters is engineered for reliable, high-accuracy measurement of gauge pressure, absolute pressure, differential pressure, and liquid level across demanding process industry applications. Built around advanced piezoresistive or capacitive sensor technology, each transmitter delivers stable, repeatable readings with excellent long-term drift performance, making it suitable for continuous monitoring and closed-loop control in petrochemical, power generation, metallurgy, pharmaceutical, and water treatment facilities.
The instruments are housed in rugged stainless steel or aluminum enclosures and feature a backlit LCD display with local push-buttons, enabling on-site configuration, zero and span adjustment, and unit selection without additional tools. A two-wire 4–20 mA output with HART protocol provides seamless integration with distributed control systems, while optional Modbus-RTU/RS485 or PROFIBUS-PA communication supports digital plant architectures.
Multiple mechanical configurations are available to suit diverse installation and process conditions. Direct-mount units offer a compact footprint for straightforward threaded or flanged installation on process lines. Flange-mount and remote diaphragm seal versions—equipped with fully welded diaphragm systems and capillary tubing—are specifically designed for high-temperature, high-viscosity, crystallizing, or highly corrosive media, effectively isolating the measuring chamber from harsh process fluids.
Depending on the model, the transmitters can be supplied with intrinsic safety (Ex ia) or flameproof (Ex d) certification for use in hazardous areas, along with optional ATEX, IECEx, or CCS approvals. Combined with wide turndown ratios, robust overpressure protection, and resistance to electromagnetic interference, this transmitter family offers a versatile and dependable solution for accurate pressure and level measurement in critical industrial processes.
