901P Loadlock Cross Reference
Sens4 offers a series of vacuum transducers that are drop-in compatible with the MKS 901P vacuum transducer.
The recommended MKS 901P equivalent replacement from Sens4 is designed for seamless integration into existing 901P load-lock installations without requiring modifications to cabling, analog pressure signal scaling, setpoint controls, digital communication protocols, or interface compatibility.
Ensure business continuity by qualifying a second source alternative to the MKS 901P Load-lock transducer or qualify our load-lock vacuum measurement solution as your first choice to take advantage of our short lead time, competitive pricing, and best-class performance.
We provide two plug-and-play alternatives to the MKS 901P load-lock vacuum transducer:
VPM-7 SmartPirani™ ATM Transducer
- Delivers comparable functionality to the 901P vacuum transducer with enhanced measurement performance.
- Features true absolute diaphragm measurement from 2 to 1000 Torr combined with high-performance MEMS Pirani vacuum measurement down to 7.5E-7 Torr.
- Includes an atmospheric switch function for precise measurements relative to ambient barometric pressure.
VPM-17 TriCAP™ ATM Transducer
- Integrates a capacitance diaphragm manometer and a piezo diaphragm sensor, providing gas-independent measurement from 5E-3 to 1333 Torr.
- The SmartPirani™ MEMS sensor ensures exceptional zero stability and measurement down to 7.5E-7 Torr.
- Ideal for users seeking a significant performance upgrade over existing 901P applications.
