356819 Bürkert: Advanced Pressure Monitoring Technology
The 356819 is a high-precision Pressure Transmitter, part of the Bürkert Type 8316 series. This compact device is designed to measure absolute or relative pressure in liquids and gases with extreme accuracy. In industrial fluid control, real-time pressure feedback is the cornerstone of process stability; the 356819 provides this via a standard 4-20 mA analog output, allowing for seamless integration into control loops. Its ceramic measuring cell is highly resistant to aggressive media and mechanical stress, ensuring a long service life in demanding environments such as water treatment, food processing, and chemical plants.
Core Technical Specifications
- Measurement Range: Check specific range (typically 0-10 or 0-40 bar).
- Output Signal: 4-20 mA (2-wire technology).
- Process Connection: G 1/4″ or G 1/2″ (Standard threaded).
- Material (Wetted parts): Ceramic, Stainless steel 1.4404, FKM seals.
- Accuracy: ≤ 0.5% of the full scale.
- Protection Class: IP65 (with cable plug).
Engineering Field Notes & Diagnostics
Lifecycle State: Active. Diagnosis: If the PLC (e.g., Siemens S7-1500) reports a «Wire Break» or «Overflow» error on the analog input card, check the loop current. A reading of 0mA usually indicates a cable fault, while a constant 4mA when pressure is present suggests a sensor blockage. Installation Advice: Avoid mounting the sensor at the bottom of a pipe where sediment can accumulate and clog the ceramic diaphragm. Use a pressure snubber if the system is prone to «water hammer» or rapid pressure spikes. Compatibility: Perfectly suited for Industry 4.0 applications. It provides the analog feedback necessary for PID loops managed by Siemens TIA Portal to control VFD-driven pumps or proportional valves.

Maintenance Tip
Calibrate the zero-point annually using a certified gauge. While the 356819 features low long-term drift, precision processes require validation to ensure optimal performance.
