KJLC 902 Series Piezo Gauges
 |
These piezo transducers combine the pressure measurement technology of a piezo transducer with an integrated electronic control circuit.
- Our KJLC 902 is an absolute direct reading transducer, enabling the measurement to be gas independent
- Transducer includes a unique temperature compensator which allows for high accuracy over a wide measurement range <1 to 1,000 Torr (<1 to 1,333 mbar)
An LED readout is available for the 902 which is controlled through the 0–10 VDC linear analog output. The readout is streamlined with the width and depth of the transducer, and adds only 1.4" to the height. The readout attaches to the transducer through the D-sub connector and has a through connector to enable the transducer to connect to the rest of the system for integration.
Features
- Low-cost transducer alternative
- Compact system design with integrated electronics and sensor in one unit
- Reduced process cycle time due to the tranducer's fast, accurate, and repeatable pressure measurements
- Transducer is suitable for harsh processes due to its clean, robust design and stainless steel construction
- Ease of operation with both digital communication and user- configurable analog output in one unit
- Digital: RS-485 or RS-232
- Digital models also have choice of Analog: 0 to 5 or 0–10 VDC
- Linear
- Logarithmic
- Process control from set-point relay with fast response time
- CE marked
Applications
- Load locks
- Vacuum processes
- Foreline and roughing pressure measurement
- Warning alarm
- Backfill and venting monitoring
- Vacuum system control relay
