Pressure transmitter O-10, 0…6 bar, 40-+100°C, 4 - 20 mA 67222739

Universal pressure transmitter for demanding industrial applications

The WIKA O-10 pressure transmitter is an advanced measurement solution designed for precise pressure monitoring in automation systems and process applications. Model 67222739 offers a measuring range of 0...6 bar gauge, an output signal of 4...20 mA, and a robust construction resistant to harsh industrial conditions.

Design and materials ensuring long-term reliability

The transmitter housing made of 316L stainless steel guarantees high resistance to corrosion and aggressive industrial media. The same stainless steel is used in the parts in contact with the measuring medium, which eliminates the risk of process contamination and extends the device's service life.

The seal made of NBR (nitrile rubber) ensures effective sealing of the G1/4A process connection according to the DIN 3852-E standard. The "condensation tightness" design protects the internal electronics from moisture and water vapor condensation.

Measuring parameters and output signal

The transmitter is characterized by a non-linearity of ±0.6% BFSL, which means high linearity accuracy of the processing characteristic. The 4...20 mA output signal in a 2-wire configuration provides immunity to electromagnetic interference and enables transmission over longer distances without degradation of measurement quality.

The power supply in the range of 8...30 V DC allows for flexible integration with various control systems. An allowable overload of 5 times the nominal range protects the sensor from damage in the event of sudden pressure spikes.

Environmental resistance and system compatibility

The IP67 protection rating guarantees full dust tightness and resistance to temporary immersion in water, enabling operation in harsh industrial environments. The M12x1 electrical connection in accordance with the cULus standard ensures a secure electrical connection.

The medium temperature can range from -40°C to +100°C, while the operating temperature of the electronics is within the range of 0°C to +80°C. This temperature difference protects the electronics from overheating at high medium temperatures.

Industrial applications and system integration

In process automation, it enables integration with SCADA and PLC systems via a standard analog signal. The compact design with a weight of 0.8 kg facilitates installation even in limited machine spaces. The M12 connector allows for quick connection using standard sensor cables available on the market.
