The OPTIBAR PC 5060 is a pressure transmitter for process pressure and hydrostatic level measurement in all kinds of process applications. It is designed for absolute and gauge pressure measurement in open tanks and – as dual version for electronic differential pressure measurement – also in closed vessels. The pressure transmitter features a ceramic capacitive measuring cell that guarantees maximum overload and vacuum resistance for high plant availability.
The measuring cell can be built into the process absolutely flush and the radially recessed position of the gasket provides additional protection in abrasive media. It is resistant to sudden temperature shocks and can handle operating temperatures of up to +150°C/ +302°F. The OPTIBAR PC 5060 comes with robust plastic and aluminium housing or hygienic stainless steel versions (incl. ingress protection IP69). It can be used in hazardous areas and Safety Instrumented Systems (SIS). The pressure transmitter comes with various diagnostics and digital communication options.
Highlights:
Remote option
The remote sensor option provides several advantages for mounting and installation. Confined spaces, which do not allow for convenient setup or control of the transmitter, benefit from a remote transmitter mounting up to 50 m away from the sensor unit. Additionally, the sensor unit is rated IP68 (25 bar), allowing for complete submersion under water for an infinite time – gauge pressure sensors then use the internal venting capillary for ambient pressure reference.
Food approvals
KROHNE OPTIBAR pressure instrumentation presents the complete line of sanitary designs and materials which meet the stringent requirements of hygienic applications. This means a huge advantage for e.g. food and beverage companies who align their production processes with a focus on product safety and production reliability.

Highlights of ceramic membran:
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 fulfill the basic requirements of the measurement task and a maximum working pressure, which limits the maximum allowable pressure without permanent drift or damage.
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 150°C / 302°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.
Diaphragm breakage detection
A diaphragm breakage of this capacitive ceramic sensor will be detected by the sensor electronics immediately after occurrence – giving it a clear advantage compared to metallic diaphragms, which can only be externally supervised with much higher technical effort.
