   >>Click here for the list.

Adoption of hastelloy C22 diaphragm offers high corrosion resistance.
Diaphragm structure enables high accuracy measurement even in lower pressure range. (Non Linearity: ±0.2%R.C.)
Atmospheric pressure reference and absolute pressure reference available.
Highly leak-proof and can be used even at high vacuum.

Measured medium Water, oil, gases or other media that will not corrode Hastelloy C22 + SUS316L.
Pressure type Positive, compound, negative and absolute pressures can be measured.
Measured Range Can be specified within the range of 50 kPa to 700 kPa (Calibration: 25~700kPa) of rated capacity.
Specify more than 50% of rated capacity as the calibration range.
Output type Specify among 4 to 20 mA (2-wire, 4-wire), 1 to 5 V, 0 to 5 V, and 0 to 10 V.
