Valcom VSD4 Sanitary Digital Differential Pressure Transmitter

Overview

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 for combination by 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.
Choose from One output (Only the output of difference pressure) and Two outputs (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
