SMART VALVE POSITIONER to ma + HART Digital Communication smar
DESCRIPTION The FY microprocessor based positioner provides fast and accurate positioning of diaphragm or cylinder actuators. The FY produces a pressure output as required to position a control valve according to a to ma input signal from a controller. The FY is compact and easy to maintain and to adjust. Remote communication based on the HART protocol enables an easy interface between the field and the control room and several interesting features that considerably reduce installation, operation and maintenance costs. The FY is part of Smar s complete series of smart devices. Local calibration and parameter setting may also be done without external devices. Reliable and Flexible By eliminating many mechanical parts seen in other positioners has a number of advantages. The valve position reading uses a magnetic sensor based or than Hall effect, without levers or potentiometers. Higher reliability since there are less parts that wear, safer since there are less moving parts, more accurate since there is less deadband from mechanical imprecision. Position sensing is done without any mechanical contact virtually eliminating wear and tear and subsequent degradation. FY directly senses longitudinal or rotary movement based on the Hall effect. The Hall effect sensor allows a remote mounting, using an up to m length extension cable. Such feature is suitable for high temperatures applications and heavy vibration places. Valve characteristics, action, damping, etc. use software configuration instead of changing mechanical cam and spring. Changing damping, action or characteristics between linear, equal percentage, hyperbolic (quick opening) makes the FY extremely flexible. Compact and modular design. Low air consumption. Easy installation. Direct non-contact position sensing. Operate with rotary or linear motion, single or double acting pneumatic actuators. Easy adjustment and parameter settings with remote HART communication or local adjustment and display Weather proof, explosion proof and intrinsically safe. Flow Characteristics change with software cams. Self-configured in few minutes Remote Hall sensor ideal for high temperatures and vibration. Optional internal pressure sensors for on line valve diagnosis. smar
OPERATION Output Module The main parts of the output module are the pilot, servo, Hall effect sensor and the output control circuit. The FY CPU produces an electronic setpoint signal for the control circuit. The control circuit receives an actual valve position feedback signal from a Hall Effect sensor. Then it compares both signds, resulting in a voltage for baffle (Piezo) for the night valve positioning. The pneumatic section in based on the well known noozle-baffle and spool valve technology. A piezoelectric disk is used as baffle in the pilot stage. The baffle is deflected when a voltage is applied by the control circuit. If a change in position is demanded, the baffle deflects. A small stream of air flowing through the nozzle is changed, causing a change in pressure in the pilot chamber. This is called the pilot pressure. For a certain range used for the operation, the pilot pressure response is linear with the battle deflection. The pilot pressure is far too low, and has no flow capacity and must therefore be boosted. This is done in the servo section, which acts as a transducer. The servo section has one diaphragm on the pilot chamber side, and another smaller diaphragm on the spool chamber side. The pilot pressure applies a force to the pilot side diaphragm which, at steady state, will be equal to the force that the spool valve applies on the smaller diaphragm. When a change in position is required, pilot pressure increases or decreases as explained for the pilot stage. A change in pilot pressure forces the spool valve up or down changing the output and output pressures until the desired position is reached. On-Board Parameters Through local adjustments the operator is able to calibrate all parameters without requiring any external programming device. A magnetic scren driver is the only tool required for all parameters and special function access. A Hand Held Terminal (HHT) is avaliable for more sophisticated operation. Calibration of the open and close position of the actuator is automatic. If another position is required the fine calibration of zero point and travel is possible using a hand held terminal or a magnetic tool. Gain and travel time are adjustable locally allowing optimization for the process conditions. FY has combined all these functions in a single unit: Direct or reverse action.
