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...

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...

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...

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...

Technical explanations for pressure transmitters Conversion chart for pressure units Oxygen and hydrogen Country-specific safety requirements and application guidelines must be observed if the medium to be monitored is oxygen or hydrogen, such as DGUV accident prevention regulations (DGUV 500, Section 2.32 and BGI 617). Pressure peak dampening If required, our pressure transmitters can also be fitted with a pressure snubber (pressure peak orifice) to protect the measuring cell against transient pressure loads such as pressure peaks due to the switching of valves, cavitation effects, etc....

General technical explanations User information Our pressure monitoring products may only be installed and started up by authorised specialists. The safety regulations of country-specific authorities must be observed, especially when working with mains voltages and oxygen, and in potentially explosive areas. Product information The technical information in this catalogue is based upon fundamental testing during product development and empirical values. The information cannot be used for all application scenarios. Testing of the suitability of our products for a specific application (such as...

RoHSII compliant Values 30% lower than in the table above must be used for brass housings. Gaseous applications In particular using additional sealant to attain the required leak tightness may be necessary for gas applications. Vacuum The values given in the technical details for the vacuum range are specified in millibars (mbar) below atmospheric pressure. Pressure change rate (~rise / ~fall) The pressure change rate denotes the pressure over time for the rising/falling pressure. The pressure change rate is specified in bar/s or bar/ms. The maximum pressure change rate for SUCO mechanical...
