925 Micro Pirani™ Vacuum Pressure Transducers
Overview
The 925 Micro Pirani™ vacuum transducer is a thermal conductivity vacuum gauge based on a unique, MEMS-based (Micro-Electro-Mechanical Systems) vacuum sensor. The 925 Micro Pirani™ offers analog voltage output, digital interface and set point relays for process controlling.
- Absolute measurement range from 10-5 Torr to Atmosphere
- MicroPirani sensor is resistant to damage from air inrush or vibration
- Analog, RS232, RS485, & EtherCAT® versions
- Optional integrated touch-screen display available for local pressure indication
- Three optional set point relays for process control
