T.4 Pressure Transmitters with SoS technology

Product catalog summary
Overview: This document outlines the technical specifications and features of high-performance pressure transmitters designed for mobile hydraulic applications. These transmitters are noted for their robust overpressure protection, extended service life, and construction from stainless steel and titanium, ensuring excellent compatibility with various media.
Specifications: The pressure transmitters utilize Silicon-on-Sapphire (SoS) technology, providing high reliability and precision. They exhibit minimal temperature error and strong long-term stability. The document details models 0705, 0710, and 0720, each offering different output signals (0.5 - 4.5 V ratiometric, 0 - 10 V, 4 - 20 mA) and supply voltages. Standard pressure ranges span from 0 to 600 bar, with overpressure protection up to 1,650 bar and burst pressure up to 2,000 bar.
Technical Details: These transmitters boast a mechanical life expectancy of 10 million pulsations and can handle pressure change rates of ≤ 5 bar/ms. They offer an accuracy of ±0.5% full scale at room temperature and long-term stability of ±0.1% FS annually. Operating within a compensated temperature range of -40°C to +50°C, they have a protection class of IP67 or IP65, depending on the connector type.
Technology: The document describes the pressure transmitters' operation, focusing on the Wheatstone bridge circuit on a membrane for pressure measurement. SoS technology employs synthetic sapphire for enhanced stability and accuracy, while oil-filled stainless steel and ceramic measuring cells provide specific application benefits.
Output Signals: The common output signals include 4 - 20 mA, 0 - 10 V, and 0.5 - 4.5 V ratiometric. Conversion formulas for pressure and voltage are provided, highlighting the necessity of suitable ohmic load for optimal performance.
Accuracy and Stability: Accuracy is specified as ±0.5% or ±1% of the full scale, accounting for zero point offset, non-linearity, hysteresis, and non-repeatability. Temperature errors are minimized within the compensated range, with long-term stability defined according to DIN 16086.
Applications and Recommendations: These pressure transmitters are recommended for applications demanding high reliability and accuracy under fluctuating pressure conditions. Custom solutions are available upon request.

Technical explanations for pressure transmitters What is a pressure transmitter? A pressure transmitter (also called pressure transducer or pressure converter) is a component used to convert a pneumatic or hydraulic pressure to an electric (usually analogue and linear) output signal, such as a current or voltage. electrical connection How does a pressure transmitter work? The pressure measuring cell fitted has a membrane (1) that is exposed to the pressure to be measured. Affixed on this membrane is a bridge circuit consisting of four ohmic resistors in the form of a Wheatstone bridge. The values...

Voltage output 0 - 10 V Transmitters with an output signal of 0 to 10 V are a commonly used variant due to their simple initial operation and straightforward scaling of the signal (0 V for 0 bar). The output load must be selected as highly resistive (with typical minimum value 4.7 kΩ). SUCO transmitters with voltage output have a 3-wire design. Conversion formula for pressure and voltage: Conversion formula for pressure and voltage: Uout = pressure applied x 10 V pressure range Voltage output 0.5 – 4.5 V ratiometric SUCO transmitters with ratiometric output are operated with a 5 V supply voltage...

Technical explanations for pressure transmitters Accuracy (to DIN EN 61298) The (measuring) accuracy of pressure transmitters is specified by SUCO as ±0.5% or ±1% of the span (also called full scale). Accuracy includes zero point offset, nonlinearity, hysteresis and non-repeatability, and is defined at room temperature and new state. This method defines the maximum deviation from the ideal line (in contrast to the BFSL method in which the average deviation is given). Other factors influencing the total accuracy, such as temperature and ageing, are specified separately. Hysteresis (to DIN EN 61298)...

digital word analogue signal analogue signal Resolution The A/D resolution (analogue - digital) of an pressure transmitter defines the smallest change of the analogue - digital - analogue conversion which takes places by the signal processing of an pressure transmitter. If for example 13-bit resolution is used for an pressure transmitter with a 100 bar setting range, the smallest signal change is 8192 steps (213). As state of the art a resolution of 12 bits and hence 4096 steps (212) is typical. Therefore pressure changes of 100 bar / 4096 = 0.024 bar can be recorded. Response time The response...
