Digital Strain Gauge Meter PSD-02A Series

Digital strain gauge meter PSD-02A is digital indicator designed for Pureron pressure sensor PC-302, 501 and 601 series. It is small size and lightweight 3-3/4 digit (3999) display equipped with two contact high-low limit comparative output as standard. Isolated circuit design between power and signal enables high noise resistance in case of multiple indicator drive with one power supply.
- Ultra small(24mm x 48mm) and lightweight (80g). Comparison setting by two contact high-low limit available
- High brightness 8mm height LED (red)
- Full display capability such as 3,000psi with 3-3/4 digit display
- Floating input isolated from power supply (DC 24V)
- High accuracy output detection by combination with Pureron pressure sensor PC-302/501/601 series
