Pressure gauge PG-208

  • Excellent stability
    A semiconductor chip is used as pressure a sensing element. State of the art circuit technology guarantees excellent temperature compensation.
  • Low power consumption
    Approx. 9000 hours (one year) continuous operation by 3.6 V lithium battery is expected due to the adoption time sharing operation method.
  • Easy reading with a large LCD display
  • With pressure switches function
    Two independent pressure setting points of HI and LO
  • With analog output (0 ~ 1 V)
  • Meets DIN sizes W72 × H72 × D40 mm
  • PG-208 is corrosion resistant due to the use of stainless steel diaphragm.

STANDARD SPECIFICATIONS[Pa version]

  • Unless otherwise specified, the specs are defined at an ambient temperature of 25 ± 5 °C, excitation voltage of 12 V DC and battery of 3.6 V DC.
