Open the catalog to page 3This specification is designed to complement other TORRIX documents (e.g. TORRIX Technical Documentation). It provides a complete description of the TORRIX Field Device from a HART Communication point of view. The FAFNIR GmbH magnetostrictive sensor TORRIX complies with the HART Protocol Revision 6. This document describes all the device specific features and documents HART Protocol implementation details. The functionality of the TORRIX is described in a way that allows its proper application in a process and its complete support in HART capable Host Devices. This document assumes the...
Open the catalog to page 4The high-precision and robust TORRIX level sensor is designed to provide continuous gauging of liquid media levels in tanks. The measuring principle used by the sensor exploits the physical effect of magnetostriction and is largely unaffected by temperature. Magnetostriction is particularly ideal where level measurements are required to be extremely accurate, e.g. in the chemical industry. The level sensor outputs measuring signals in the range 4 to 20 mA. Available in lengths of 200 to 6,000 mm, it is compatible with a variety of tank dimensions. It also comes in the following...

Open the catalog to page 8Command #72 (Squawk) The device will flash the LED of the Local Panel (only visible after removing the transmitter head cover) for about 5 seconds after Command #72 has been received. While the LED is flashing the loop current is set to 12 mA and the Output Current Fixed bit in the Response Code will be set. A Death or serious injury could result from using Command #72 when the transmitter is used for process control at that time. So be sure that the transmitters analogue output is not used for process control when using Command #72. Command #73 (Find Device) The device will only answer...

Open the catalog to page 10The Device Variable 0 contains the result of the level measurement done with float 1 (upper float). This level represents the total level. Summary of Device Variable 0 properties: * see Section 13.1.1 for additional information. The transmitter is not always equipped with a second float, if there is no second float the measurement data of Device Variable 1 is set to Not-A-Number. TORRIX with HART protocol Page 11/27
Open the catalog to page 11* see Section 13.1.1 for additional information. The transmitter is not always equipped with a second float, if there is no second float the measurement data of Device Variable 3 is set to Not-A-Number. 6 Dynamic Variables The device supports 4 Dynamic Variables (PV, SV, TV and QV) that can be mapped from the Device Variables. 6.1 Mapping of the Dynamic Variables Use Command #50 (Read Dynamic Variable Assignments) to get the current mapping of the Dynamic Variables. To change the mapping use Command #51 (Write Dynamic Variable Assignments). For the default mapping of the Dynamic Variables...
Open the catalog to page 12Non-Primary Variable Out Of Limits (bit 1) Non-Primary Variable Out Of Limits is set whenever the value of one of the Non-Primary Variables exceeds the upper or lower limit of the sensor that belongs to this variable. More Status Available (bit 4) More Status Available is set whenever Device Malfunction is set. Device Malfunction (bit 7) Device Malfunction is set whenever the Self-Test has detected a serious problem with the device. This problems will also set the corresponding Additional Device Status bit. See Section 7.3 for more information about the Additional Device Status bits....
Open the catalog to page 13Description of the Device Specific Status bits: * Device Specific Status bits that are not used are set to zero. HART Parameter Error It has been detected that the HART parameters have illegally been changed. Transmitter Parameter Error It has been detected that the transmitter parameters have illegally been changed. Measurement Error It has been detected that a measurement is not possible. Error Counter Error It has been detected that there are to many errors during the measurement. Low Voltage Error It has been detected that the supply voltage is to low. The analogue output has been...
