Smart Pressure Transmitter
This series pressure transmitter pressure sensitive core adopts
high performance silicon piezoresistive pressure filling core. The
internal ASIC converts the sensor millivolt signal into standard
voltage, current or frequency signal, which can be directly
connected with computer interface card, control instrument,
intelligent instrument or PLC. Current output mode can be used for
distance transmission. It has small volume, light weight, all
stainless steel sealing structure and can work in corrosive
environment. The product is easy to install and has high
anti-vibration and anti-impact performance. It is widely used in
process control, aviation, aerospace, automobile, medical
equipment, HVAC and other fields.
