NG # 04012-HW-KELLER-034
MF # KEL-10L-s
The KELLER Series 10L is an unamplified, piezoresistive OEM pressure transducer featuring a standard $\varnothing 19\text{ mm}$ body diameter. Positioned as the most widely used industrial size in KELLER’s capsule lineup, its larger diaphragm area delivers high sensitivity, exceptional linearity, and lower thermal error coefficients compared to smaller sub-miniature models.

Get A QuoteThe pressure transducers of the 10L series have a robust housing of stainless steel, giving them optimum 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 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.
