Digital Strain Gauge Meter PSD-02B Series

Digital strain gauge meter PSD-02Bis 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
