NG # 04013-HW-KELLER-035
The Keller Series 9L is a unamplified piezoresistive pressure transducer capsule designed for OEM integration. Unlike complete transmitters with housing and cable glands, the 9L is a core transducer cell meant to be built directly into custom manifolds, valves, specialized instrumentation, or system enclosures.

Get A QuoteThe pressure transducers of the 9L series have a compact, robust housing made of stainless steel, giving them outstanding long-term stability for a range of OEM applications. The metal diaphragm is welded on front-flush and gap-free, separating off the piezoresistive pressure sensor, which is made of silicon, from the measuring medium. Every pressure transducer is measured over the entire pressure and temperature profile and is supplied with a detailed calibration sheet.https://img.directindustry.de/images_di/2ai/save-En.gif
