The OPTIBAR PC 1010 is an ultra-compact pressure transmitter with recessed or front-flush ceramic diaphragm for gauge pressure measurement. It offers a cost-effective solution for basic applications with liquids, gases and steam up to 40 bar / 580 psi and temperatures up to +125°C / +257°F. Thanks to its robust design, the pressure transmitter is ideal for long-term stable pressure and level measurement in many industries.
The capacitive ceramic measuring cell offers a high degree of safety and reliability. It does not require any fill fluid and is highly resistant to overpressure and overload and therefore also resistant to pressure surges. The high-performance ceramic also makes the pressure transmitter extremely robust against abrasive and aggressive media. The OPTIBAR PC 1010 allows for a space-saving installation. It comes with various threaded connections, which are available in stainless steel as well as in non-metallic materials PVDF and PP-HT for increased corrosion resistance.
Highlights:
Highest overload resistance
Pressure spikes have an extensive effect on the measurement accuracy and physical integrity of the measuring cell. A robust pressure sensor provides high factors between the nominal range to fulfil the basic requirements of the measurement task and a maximum working pressure, which limits the maximum allowable pressure without permanent drift or damage.
Dry measuring cell
The capacitive measuring principle with a ceramic diaphragm enables precise and reliable pressure measurement without any fill fluid inside the measuring cell. This reduces the risk of leakage and ensures contamination-free measurement.
Vacuum resistance
Vacuum conditions can have a severe impact on the measurement performance of pressure transmitters. Outgassing of the fill fluid in the metallic diaphragm systems is one of the most frequent issues. Ceramic sensors do not have fill fluid and are therefore perfectly resistant for process temperatures up to 125°C / 257°F.
Corrosion resistance
Due to its high chemical stability, 99.996% pure sapphire ceramic is passivated against chemical corrosion even in harsh environments. This property of corrosion resistance is also one of ceramics’ advantages over metals, plastic and other materials.
Hardness
Sapphire ceramic is 10x harder than stainless steel – fluids with solid content do not have any impact on the longevity or performance of the sensor.
Hydrogen resistance
Hydrogen can diffuse under certain process conditions through thin metallic diaphragms, causing offsets and drift. Ceramic is impermeable to atomic hydrogen due to its molecular structure.
