Valcom VPRF Series
Pressure Transducer for Flush type Middle High Pressure
- Suitable for measurement of viscous media since the flush type (no feed port) wetted part is hardly clogged up.
- Wetted part constructed integral with diaphragm does not use any sealed liquid, offering durability, reliability and long life.
- High accurate (Non Linearity: ±0.5%R.C.)
