- Product description
Brief introduction
ACD-302 Pressure transmitter is new product developed on our history experience. This transmitter cannot only output signal 4-20mA, but also can add RS485 communication. It can connect to computer or other interfaces with communication software and store, process and report output. It adopts the most advanced micro power and perfect software technology and five figures backlit displayed on LCD screen.
1. 11 units display: Pa kPa MPa psi bar mbar kgf/cm2 inH2O mmH2O inHg mmHg
2. 0.1 ~ 10 seconds per time acquisition speed
3. support RS485 and RS232 communication or 4-20mA or 1-5V output, free to choose
4. radial, axial, plate, spilt and investment installation type
5. five figures display on LCD screen and backlit function easy to read at night
6. never drop communication equipment, the trunk support 255sets of RS485 counter equipment
7. signal isolation technique, anti-electromagnetic interference and RFI technique
8. zero stable technology, increase the stability of the instrument
Product application
1. replace the imported transmitter outdoors or under bad environment
2. acquisition or communication whole day in the pit
3. oil well and gas well pressure monitoring and remote transmission
4. suit for large areas pressure parameters group acquisition
5. can work well in corrosive, impact and versatility environment
6. equipped with AncnView-T digital instrument test monitoring software
