Damping (DAMPING) Pressure transmitter output signals that are noisy as a result of the process can be smoothed (damped) electrically. The additional time constant can be set between 0 s and 60 s in increments of 0.0001 s. Damping does not affect the value shown on the digital display as a physical unit. It only affects the parameters derived from this, such as the analog output current, free process variable, input signal for the controller, and so on. The damping adjustment can be performed in different ways: – Via the the local HMI: Enter the menu: > Device Setup > Output Scaling > Damping Set the damping to the desired value. – Via the Asset Vision Basic Software: See Asset Vision Software Operating Instructions – Via the Hand Held Terminal See relevant operating instruction Transfer function The 266 Pressure Transmitter provides a selection of output functions, as follows: – Linear for differential, gauge and absolute pressure or level measurements – Sq.

Root (x3) for open channel flow measurements using rectangular or trapezoidal weir – Sq. Root (x5) for open channel flow measurements using V-notch (triangular) weir. – Bidirectional Flow – Custom linearization table – Cylindrical lying tank – Spherical tank These output functions can be activated using a Configuration Tool (Digital LCD Integral Display, Hand Held Communicator or PC based software as Asset Vision Basic). The transfer function can be applied to the analog signal 4 to 20 mA only or also to the indication (in engineering units).vant operating instruction Transfer functions description Linear Using this function, the relationship between the input (measured value), expressed in % of the calibrated span and the output is linear (i.e.: at 0% input, corresponds 0% output 4mA, at 100% input corresponds 100% output - 20mA). No further settings are possible here. Square root Using the Square Root function, the output (in % of the span) is proportional to the square root of the input signal in percentage of the calibrated span (i.e.: the instrument gives an analog output proportional to the rate of flow). The possibility to have the full Square Root function is given. To avoid the extremely high gain error with the input approaching zero, the transmitter output is linear with the input up with a slope of 1 up to 0.5% and then still linear with the appropriated slope to a programmable percentage value between 10 % and 20%. This option is offer in order to ensure a more stable output when the signal is close to zero avoiding errors due to the high gain of the square root. To neglect the values with the input approaching zero, the transmitter output is zero with the input up to a programmable percentage value between 0 % and 20%. This option is offer in order to ensure a more stable flow measure. This option is possible for all the listed output functions. ).vant operating instruction

The signal is then converted in the front-end electronics in a digital form and the raw values are computed by a microcontroller to a precise primary output linearization. – Assure that the Write Protect Mode switch is in Write Protect condition.Architecture description and principle of operation The instrument consists of two main functional units: – Primary unit – Secondary unit The pressure transducer unit includes the process interface. In the primary unit the process fluid ( liquid. It shall be within the stated safety accuracy (2% of sensor range). C 73 . If a difference between the two measurements is detected the analog output is driven to a safety condition. The feedback loop is obtained by an additional A/D converter put at the end of the output stage. compensating for the combined effects of sensor non linearity. It is also possible to put the device in write protect condition by a dedicated HART command. the sensor and the front-end electronics. the Secondary Unit includes the electronics. Internal diagnostics algorithms are implemented to check correctness and validity of all processing variables and the correct working of memories. The two units are mechanically coupled by a threaded joint. it simultaneously produces variations of the primary physical value depending on the sensor technology (capacitive. Principle of operation The principle of operation is as follows. In that condition all kind of configurations of the device are disabled. These failures do not affect the transmitter operations. – Power-on the transmitter: the transmitter performs automatically a self-test that consists in the operations below: ROM test RAM test Test of the analog output stage and of the feedback A/D converter Test of the power supply voltage Non volatile memory test – Apply pressure up to 50% of the calibrated range and check the output value. the terminal block and the housing. of static pressure and temperature changes on the basis of the “mapped” parameters calculate in the manufacturing process and stored in the memory of the Front End electronics. digital communication using the standard “HART” protocol is implemented as part of this unit. The bi-directional. In any case the switch position has the priority on the software command. inductive or piezoresistive). Warning After any configuration operation. Calculations follow independent flows and they are compared in the microcontroller in order to validate the output pressure signal. As the sensor detects the pressure changes. The measured values and the sensor parameters are transferred via a standard serial digital communication to the secondary unit where the communication board is fitted. 2600T Series Pressure transmitters | OI/266/HART-EN Rev. Operating mode enabling and disabling Operating mode can be enabled/disabled depending on the switch position. The output data value is converted into a pulse-width signal that is filtered and that activates the 4-20 mA transmitter. The output stage is also checked by reading back the analog output signal and by reading the power supply voltage. gas or vapour ) exerts pressure on to the sensor via flexible. The proof tests consist in the following operations: – Switch off the device. which translates the 4-20 mA signal into a digital form suitable to be compared by the microcontroller. Commissioning and configuration issues The transmitter is considered in safety condition (normal operating mode) when the write protect switch placed outside the transmitter housing below the metallic nameplate is in Write Protect. the transmitter must be put in operating mode Proof tests Safe undetected faults could occur during the operation of the transmitters. To maintain the claimed Safety Integrity Level (SIL 2) a proof test procedure is requested every 10 years. corrosion-resistant isolating diaphragms and capillary tubing containing the fill fluid.
