KJLC 910 Series Wide-Range Combination Gauges

KJLC 910 Series Wide-Range Combination Gauges

These Kurt J. Lesker transducers are based on direct-reading absolute Piezo and Pirani sensors.

Features

• Digital communication enables all adjustments and monitoring to be delivered real-time, via a host computer
• Provides a 1–9 VDC analog output signal at the male 15-pin high-density D-sub connector
• Transducer offers a smooth output between the two sensors and reads from both sensors in the 5 to 15 Torr (6.7 to 20 mbar) range
• Transducer measurement range is from 10^-5 to 1,500 Torr (10^-5 to 2,000 mbar)
• Three independent relay set points provide process control
• Set-point features can be set, adjusted, and monitored through the digital port

Unlike traditional Pirani gauges, the compact element in the Pirani portion of the 910 Series is made of a one-millimeter square silicon chip, enabling the measurements to be made in a very small volume. A traditional Pirani sensor has a measuring range from 10^-3 Torr (133 to 10^-3 mbar) to about 100, rapidly losing sensitivity above 10 Torr (13 mbar). Because the size of the sensing portion of the Pirani is so small, it has a range from atmosphere down to 10^-5 Torr (mbar).

Like all thermal conductivity sensors, the Pirani is gas-type sensitive. The Piezo measures independent of gas type. The 910 provides a digital leak detection output that measures differential reading between the Piezo and Pirani. This makes it a simple solution for locating medium to fine leaks in vacuum systems.
