DPT-60
Micro differential pressure transmitter
Ultra low pressure cleaning medium
- APPLICATION
- Electronics industry clean room
- Machinery manufacturing
- FUNCTIONAL CHARACTERISTICS
- Output mode
- Micro differential pressure transmitter adopts RS-485 communication circuit
- Modbus standard communication protocol. Refer to DPT60 Communication Protocol for the specific protocol of using 0x03 (read holding register) and 0x06 (write a single register) function codes in the protocol. Among them
- the array pin is a RS-485 AB wire matching resistance jumper. When the communication distance exceeds 300 meters
- the terminal instrument jumper can be connected to reduce the reflection interference of the communication circuit signal. The DPT60 outputs RS-485 digital signals
- the DPT62/DPT63 outputs 0~5/10VDC voltage and RS-485 digital signals
- and the DPT65 outputs 4~20mA current and RS-485 digital signals.
- Reset button
- Use this button to calibrate the zero pressure value when the differential pressure between the positive and negative pressure inlet is zero (when pressed
- the LED lights up at the same time).
- Set button
- Calibrate the pressure value under the condition that the precision instrument is used to provide the pressure source. (Please do not use it easily)
- Output response time setting
- Set the response time when the DIP switch is set to the status from to:
