Valcom Sanitary Digital Differential Pressure Transmitter VSD4 series

VSD4 Can be specified within the range of 50 kPa to 1000 kPa of rated capacity. It's suitable combine with batch control/PID Controller which needs a pulse output of 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 the 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
