- 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.

A pressure switch suitable for controlling gauge pressure or differential pressure from ±250Pa to ±200kPa, with relay ON/OFF output. When the set threshold is exceeded, the built-in relay activates, the LED on the front of the switch lights up, and an alarm sounds from the built-in buzzer. The alarm can be set to activate when the measured value exceeds or falls below the set threshold. It is possible to choose from one or two threshold operation modes. By adopting a high-precision silicon-type piezoelectric pressure sensor with temperature compensation, excellent linearity, reproducibility, and long-term stability are achieved. The auto-zero function of the low-range model (HD402TR1L) enables stable measurements without the need for recalibration over long periods. The HD402TR□L series pressure switches are equipped with a 4-digit LCD display, and all models allow for the selection of measurement units. The high stability against sensor aging and temperature changes significantly reduces maintenance work for aging drift and zero-point correction. ▲ Adoption of high-precision, temperature-compensated silicon-type piezoelectric pressure sensor ▲ C contact (NC/NO) relay output, standard equipped with 4-digit LCD display ▲ Threshold, hysteresis, and delay time settings available, auto-zero function
