The Swiss HUBA 511 series pressure transmitters (pressure sensors) feature a compact design with high longevity, precision, temperature stability, and electromagnetic compatibility. They meet the highest standards in mechanical stress resistance, EMC compatibility, and operational reliability, making them particularly suitable for all demanding industrial applications. These sensors utilize ceramic technology developed by HUBA CONTROL over the past decade and have been used in millions of applications. Thanks to the integrated electronic design, the 511 series offers high accuracy across its temperature range. In summary, the 511 series transmitters are characterized by their small size and excellent cost-performance ratio. Main application areas: vacuum equipment, air compressors, hydraulic equipment, etc. Product Features ◆ Superior electromagnetic compatibility (EMC) ◆ Reverse polarity protection, electrostatic protection up to 500 VDC ◆ Over-medium stop system (burst protection) ◆ Quickon quick connection, saves 60% wiring time; UL, CSA, CE certified ◆ Sealing materials: optional FPM, NBR, or other customer-requested materials ◆ Dynamic response: suitable for both static and dynamic measurements, response time <2 ms, typically 1 ms Technical Parameters Relative pressure: -1 to 600 bar Absolute pressure: 0 to 25 bar Overload pressure: 3.0 × full scale (for range -1 to 4 bar) 2.5 × full scale (for range 6 to 400 bar) 2.0 × full scale (for range 600 bar) Burst pressure: 3.0 × full scale (for range -1 to 4 bar) 2.5 × full scale (for range 6 to 400 bar) 2.0 × full scale (for range 600 bar) Protection rating: IP67 Housing material: Stainless steel 1.4305 (AISI 303) Temperature range: -15°C to +125°C Application temperature (medium temperature under sealed conditions) FPM: -15 to 125°C; NBR: -25 to 85°C FPM (special): -40 to 150°C Voltage: 8.0 to 33 VDC, output 4-20 mA Sealing material: Optional FPM, NBR, or other customer-requested materials Weight: 85 g for internal thread, 95 g for external thread Accuracy: Combined linearity, hysteresis, and repeatability < ±0.3% FS Dynamic response: Suitable for static and dynamic measurements Response time <2 ms, typically 1 ms Common Models Huba 511.900003572 Pressure sensor -1-0 BAR 4-20 mA R1/4 Huba 511.911003571 Pressure sensor 0-1 BAR 4-20 mA R1/4 Huba 511.911004041 Pressure sensor 0-1 BAR 0.5-4.5V Huba 511.914001571 Pressure sensor 0-2.5 BAR 0-5VDC Huba 511.914603571 Pressure sensor 0-2.5 BAR 4-20 mA Huba 511.914603571W Pressure sensor 0-2 KG/cm2 4-20mA PT thread R1/4 Huba 511.915003141 Pressure transmitter 0~4 bar 4~20 mA G1/4 Huba 511.915003571 Pressure sensor 0-4 BAR 4-20 mA 2-wire Huba 511.917003141 Pressure transmitter 0~6 bar 4~20 mA G1/4 Huba 511.917003141-1 Pressure transmitter 1005035MU511.917003141 0-6 bar 4~20 mA Huba 511.917003541-1 Pressure transmitter 0~6 bar 4~20 mA 1003290 MU511.917003541 Huba 511.917003571 Pressure sensor 0-6 BAR 4-20 mA R1/4 Huba 511.930002571 Pressure sensor 0-10 bar 0-10V Huba 511.930003141 Pressure transmitter 0~10 bar 4~20 mA G1/4 Huba 511.930003771 Pressure sensor 0-10 BAR 4-20 mA R1/4 Huba 511.930004041 Pressure sensor 0-10 BAR 0.5-4.5 V Huba 511.930007071 Pressure transmitter 0~10 bar 0~10V Huba 511.931003771 Pressure sensor 0-16 BAR metal head Huba 511.932003141 Pressure transmitter 0~25 bar 4~20 mA Huba 511.932003571 Pressure sensor 0-25 BAR 4-20 mA Huba 511.933003242 Pressure sensor 0-40 BAR 4-20 mA with AMP Huba 511.933003572 Pressure sensor 0-40 BAR 4-20 mA R1/4 Huba 511.940003142 Pressure transmitter 0~60 bar 4~20 mA Huba 511.940003572 Pressure sensor 0-60 BAR 4-20 mA R1/4 Huba 511.941003542 Pressure sensor 0-100 BAR 4-20 mA Huba 511.941003572 Pressure sensor 0-100 BAR 4-20 mA R1/4 Huba 511.942003542 Pressure sensor 0-160 BAR 4-20 mA Huba 511.942003572 Pressure sensor 0~160 BAR 4~20 mA R1/4 Huba 511.943002542 Pressure sensor 0-250 BAR 0-10V
