Valcom VSD4 Sanitary Digital Differential Pressure Transmitter Can be specified within the range of 50 kPa to 1000 kPa of rated capacity. It’s suitable combine by batch control/PID Controller which need pulse output 4-20mA
- Determines differential pressure by computing the outputs from two pressure sensors.
- Output 4-20mA (2 wire system) scaling function.
- Chooses from One output (Only the output of difference pressure) and Two output (The output of difference pressure + The Output of low-pressure side)
- Pressure port with higher strength.
- Safe and reliable construction with no sealed liquid.
- Standard functions
- Display switch (Differential pressure, High pressure, Low pressure)
- Damping
- Loop check function
- FIX zero
- Zero shift
- Maximum/Minimum monitoring function
- Setting output status at error
- Key lock function
