1 TEK-BAR 3100 Series Smart Pressure Transmitter

2 2 Introduction The Tek-Bar 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. 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. Working principle of Tek-Bar 3100-D,G,H model The Tek-Bar 3100-D,G,H, A smart pressure transmitter used Capacitance pressure sensors. It consist of two metal plates that are separated by sensing diaphragm. The capacitor plate is filled with silicone oil. The pressure applied deflects the diaphragm and is transferred through the oil onto the sensor. The capacitance characteristics of the sensing element changes. These signal transfer to the electronic circuitry of transmitter that converts the change in capacitance to the output signal. Capacitance transmitters are available are configured for either differential or gauge pressure measurement. Usual outputs are voltage or current. Capacitance can be calculated using the formula: C= ε(a)/(d) Where, C- Capacitance, ε-dielectric Constant A-Area of plate d-distance between capacitor plates Leadwires Sensor module Capacitor Plates Sensing Diaphragm Rigid Insulation Sensor Silicone oil Isolating Diaphragm Welded Seals

4 4 Functional Block Diagram Functional Block Diagram: The Electronics module consists of a circuit board sealed in an enclosure. There are a MCU module, a power module, an analog module, a LCD module and a terminal module in a transmitter. The MCU module acquires 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 HARTbased Configurator. The Power module have a DC-to-DC Power conversion circuit and an Input/output isolation circuit. An optional LCD module plugs into the MCU module and displays the digital output in user-configured unit.

As a result, the modified flanges must be additionally provided. Multi-planar pressure transmitter has been made in an effort to solve the problems occurring in the related art, and an object of this multi planar is to provide a pressure transmitter, capable of being vertically installed without separate adaptor or various types of brackets regardless of the position of each fluid inflow line.
