4, Gilchrist Road, Northbank Industrial Park, Irlam, Manchester, UK. M44 5AY. Made in Britain ' Email: sales@budenberg.co.uk Web: www.budenberg.co.uk Budenberg's range of transmitters includes a complete range of "intelligent"high performance transmitters for Temperature, Gauge, Absolute, Vacuum & Differential pressure measurements for standalone monitoring and/or closed loop control applications.These "intelligent" microprocessor-based "Smart" transmitters features a two-wire loop powered 4 to 20mA current outputs with "Digital" HART as standard (Foundation Fieldbus optional) communication(s) for seamless Communicator(HHC). "integration with a host DCS, PLC, SCADA, AMS, PDM and/or a local Hand Held communicator The BGL-DPT1000 series of smart transmitters have excellent stability high accuracy and include features that facilitate easy installation start up and minimum maintenance, thereby lowering process downtime and overall cost of ownership in the long run. Budenberg transmitters are products with analog (4/20mA- 2 wire) and digital (HART or Foundation Fieldbus communication protocols for seamless integration with a host control System such as DCS, PLC, SCADA, AMS, PDM and/or Hand Held Communicator (HHC). Through Digital HART protocol one can easily acquire process measured variable, configure and modify various Parameters (Range, Tag Name and Damping, Transfer Function, (Range, Tag Name and Damping, Transfer Function, Trimming These transmitters are equipped with an automatic temperature compensation function integrated into its advanced signal processing circuitry to ensure high reliability and performance corresponding to change of ambient temperature. _ Superior Performance _ High Reference Accuracy :+/-0.075% of calibrated span _ Long-Term Stability _ Data Configuration with HART Configurator _ Zero Point Adjustment _ Continuous Self-Diagnostic Function _ Automatic Ambient Temperature Compensation _ Fail-mode Process Function _ EEPROM Write Protection _ Flexible Sensor Input: DP, GP, AP, Vacuum _ Various Output: 4 ~20mA , Digital Signals _ Setting Various Parameters : Zero/Span, _ Trim, Unit, Fail-mode, etc _ Self Diagnostic Function : Sensor, Memory _ Digital Communication with HART protocol _ Explosion-proof Approval & Intrinsic Safety Approval: KOSHA, KTL CSA,FM, ATEX The heart of Budenberg smart transmitter is a microprocessor-based high performance module. In addition, each transmitter is ambient temperature characterised using state of the art technologies to ensure maximum transmitter accuracy and minimized drift over a wide range of operating temperatures. On integrated sensor models such as in BGL-PTG1000 series transmitters the characteristics data of its sensor are stored in internal non-volatile EEPROM to minimize measuring error. On non sensor transmitter models such as BGL-TT1000 temperature transmitters, it has a linearization table built in wherein user can modify the various necessary values in field per the added temperature sensor (RTD or T/C) characteristics to get better accuracy from the overall measurement system. Its integral microprocessor module then automatically converts the required value referring to the customized linearization table. All transmitters include advanced self diagnostic functions for detecting any malfunctions of sensor and/or fault of A/D converter, internal memory and microprocessor. All diagnostic/error status is transmitted to a connected Master by analog current signal (fail mode current 3.75mA or 22mA) or digital HART (or FF) communication. The transmitters have Last Value Status (L V S) function for safety of instrumentation. When the sensor input occurs in abnormal status, output is fixed to the previous value and when the recovery to normal status, output is updated to the current value. If abnormal status of sensor is being continued during the defined interval, the fault is recognized as a sensor failure & reported accordingly for corrective action.

Electronics Module The Electronics module consists of a circuit board sealed in an enclosure. There is a MCU module, a power module, an analog module, a LCD module and a terminal module included within the transmitter.AII circuit boards are tropicalised suitable for hot and humid, and damp and cold climates. The MCU modules acquire the digital value from the analog module and apply correction coefficients selected from EEPROM. The output section of the power module converts the digital signal to a 4-20 mA output. The MCU module communicates with the HART-based Configurator or Control...
