The ATM420-Single offers a cost-effective and user-friendly solution for facilities where a single differential pressure measurement is sufficient. Whether you're managing a small lab, a cleanroom corridor, or a minor procedure room, this compact system gives you instant visual feedback to ensure your environment remains compliant and safe.
The standard measuring range is -50 to +50 Pa, which is suitable for most applications such as isolation rooms, cleanrooms, and operating rooms. A differential pressure transmitter has two pressure connection ports, allowing it to measure the pressure difference between two spaces—such as between a corridor and an airlock, or a corridor and a patient room. The ATM420-Single displays this single differential pressure value clearly on the screen.
Through the configuration menu, you can assign a custom label above the measured value, making it easy to identify which room or area is being monitored. You can also set low and high alarm thresholds, as well as an alarm delay (in seconds) to prevent false alarms—such as when someone briefly opens a door. When the measured pressure exceeds the threshold, the display color changes immediately to indicate the alarm status.
The internal buzzer is optional and configurable. You can set the buzzer interval (in seconds) for on/off operation according to your preference.
Every ATM420 plug-and-install set includes a full-color touchscreen display, a flush-mount enclosure, and one differential pressure transmitter.
All you need is a 24VDC power supply and a connection cable between the ATM420 and the transmitter. This complete package ensures accurate and reliable room pressure monitoring in critical environments.
