T.2 Robust pressure transmitters hex 22

Product catalog summary

Overview: The document provides detailed specifications and technical information about robust pressure transmitters designed for low pressures, including vacuum applications. These transmitters offer high overpressure protection, long life expectancy, and are suitable for hydrogen and oxygen applications.

Specifications:

Material: Housing and wetted parts are made of stainless steel (1.4305 / AISI 303), ensuring excellent media compatibility.
Sensor: Utilizes a highly-sensitive piezo-resistive sensor filled with oil for high accuracy, repeatability, and long-term stability.
Sealing Materials: Available in NBR, EPDM, and FKM, allowing use across a broad temperature range and with various media.

Technical Details:

Output Signals: Options include 0.5 - 4.5 V ratiometric, 0 - 10 V (3-wire), and 4 - 20 mA (2-wire).
Supply Voltage: Ranges from 5 VDC ±10% to 32 VDC depending on the model.
Pressure Ranges: Standard ranges from -1 to 100 bar with overpressure protection up to 200 bar.
Accuracy: ±0.5% full scale at room temperature, with long-term stability of < ±0.2% FS per year.
Temperature Range: Compensated range from -10°C to +70°C, with ambient and media temperature ranges varying by seal material.

Performance and Durability:

Mechanical Life Expectancy: 10,000,000 pulsations at rise rates up to 1,000 bar/s.
Vibration and Shock Resistance: Vibration resistance up to 20 g and shock resistance of 500 m/s².
Protection: Built-in protection against reverse polarity, short-circuit, and overvoltage.

Applications: Suitable for various applications including hydraulic fluids, brake fluids, and gases like hydrogen and oxygen, with specific limitations for oxygen applications.

Compliance: RoHSII compliant and meets EMC standards (EMC 2014/30/EU).
