Pressure Transducer for Ultra-Pure Water The KL-91 is a pressure transducer suitable for use in monitoring pressure of various high-purity fluids. The superior design provides for minimal “dead volume” which reduces the potential for contamination of the measured fluid. The KL-91 is available in two construction type: inline or insertion. The body construction meets IP-65 requiremnents and EMC resistant the level of CE.
KL-91 Series Pressure Transducers Features
- ± 1 % full-scale accuracy
- All PFA/PTFE wetted part construction and PTFE coating on Alumina Sensor
- No 'O'-ring seals or fill fluids
- Choice of end fitting: Flare, Pillar, 20S, or Tube
KL-91 Series Pressure Transducers Applications
- High-purity DI water, and CMP slurry
