Micro Pressure / Differential Pressure Transmitter / HD402T Series

Pressure transmitter suitable for measuring gauge pressure or differential pressure from full scale 50 Pa to 200 kPa.

- Uses a silicon-type piezoelectric pressure sensor equipped with high-precision temperature compensation, excellent linearity, reproducibility, and long-term stability. - The sensor's output signal is converted to the following output signals depending on the model: [HD402T] Voltage DC 0-10V or active type current 0/4-20mA output [HD402AT] 2-wire (current loop) 4-20mA output [HD402ST] RS485 Modbus-RTU output - The current output signal is resistant to interference from noise and can be transmitted over long distances. - In addition to full scale (F.S.), it is also possible to set the measurement range for positive scale (0 to +F.S.) or positive-negative scale (-F.S. to 0 to +F.S.). - Settings can be made using dip switches mounted on the PCB or by connecting a serial port to a PC. - An option with an LCD display capable of 4-digit display is available. ▲ DC 0-10V/4(0)-20mA/RS485 Modbus-RTU output ▲ Measurement units (Pa/kPa/hPa (mbar)), and full scale (large, medium, small) settings are possible. ▲ Settings for positive (0 to +FS) and positive-negative scale (-FS to 0 to +FS) are possible.
