For monitoring air pressure under regulatory environments.
The PDT101 differential pressure transmitter is designed for demanding clean room requirements. This product can be integrated into the Vaisala viewLinc monitoring system. It measures and monitors differential pressure in regulated environments. It is ideal for high-performance clean room environments in the life sciences, semiconductor, and electronics industries.
High-precision measurement of gauge pressure and differential pressure based on atmospheric pressure.
The HD404T series micro-pressure and micro-differential pressure transmitters accurately measure gauge pressure and differential pressure based on atmospheric pressure within the following measurement ranges: ● Analog output models: Full scale from 50Pa to 1000Pa ● RS485 Modbus-RTU output models: Full scale of 250Pa, 1000Pa, 100hPa These transmitters utilize sensors based on silicon micromachining technology, providing exceptional long-term linearity, reproducibility, and stability. The output signal from the sensor is converted into either standard analog signals (current: 4–20mA or voltage: 0–10V) or digital signals in Modbus-RTU format, which are highly noise-resistant and capable of long-distance transmission, depending on the model. ▼ Micro-pressure and micro-differential pressure transmitters with a minimum measurement range of 0–50Pa ▼ "Auto-Zero" function for regular automatic offset correction ▼ Dual analog output of 4–20mA/DC 0–10V ▼ Switchable LPW/HIGH (measurement range) and FAST/SLOW (response speed) settings
For clean rooms in the life sciences and high-tech fields.
PDT102 is a high-performance device primarily designed for clean rooms in the life sciences and high-tech fields, achieving excellent accuracy, sensitivity, stability, and durability through robust MEMS silicon sensor technology.
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.
