Compact, Digital Display Pressure Sensors - PSA / PSB Series
The PSA/PSB Series are compact, digital display pressure sensors designed for sensing non-corrosive gases. Featuring a high-brightness red LED display and a selectable response time for chattering prevention, these sensors offer versatile output modes including Hysteresis, Automatic Sensitivity Setting, Independent 2 Output, and Window Comparative Output. They are equipped with an analog voltage output (1-5VDC) and include reverse power polarity and overcurrent protection circuits. The one-touch connector type facilitates easy wiring and maintenance, making them suitable for various industrial applications.

| HHH | Applied pressure exceeds High-limit of display range | Apply pressure within display range |
| LLL | Applied pressure exceeds Low-limit of display range | Apply pressure within display range |
Cautions
- Use within the range of specification.
- After supplying power, it takes 3 sec. to work.
- Do not use with flammable gas; not an explosion-proof structure.
- Avoid direct contact with water, oil, thinner, etc.
- Wiring must be done with power off.
- Do not insert sharp objects into the pressure port.
- When using switching mode power supply, frame ground terminal should be grounded.
- May cause malfunction by noise when wiring with power line or high voltage line.
