Reliability

High accuracy and stability for critical industrial applications

Fast response: ~120 ms (Direct Mount), ~200 ms (Remote Mount)

Suitable for aggressive, corrosive, viscous, or particulate-laden media

Optional flushing/venting connection for maintenance

Wetted Materials

Corrosion-resistant materials for diaphragm and seal housing

Flanges available in Flush (1.5″, 2″, 3″) and Extended (3″, 4″) sizes

Temperature & Environmental Resistance

Operating temperature: −30 °C … +80 °C (Direct Mount)

Compensated for temperature changes; supports vacuum measurement down to ~0.013 kPa (abs)

Capillary compensation minimizes temperature-induced drift

Measurement Ranges

M-range: 1…100 kPa

H-range: 5…500 kPa

V-range (Flush): 0.14…14 MPa

V Extended: 0.14…7 MPa

Features

• Direct Mounted — diaphragm attached directly to the flange/thread of the instrument.
• Remote Mount (Flanged) — diaphragm located remotely, connected via capillary lines.
• Measuring pressure, level, density, or flow of liquids and gases
• Ideal for challenging media: extreme temperatures, aggressive chemicals, viscous or toxic fluids, solids-laden fluids
• Industries: chemical, pharmaceutical, oil & gas, energy, etc.
