The KOBOLD Differential Pressure Transmitter model PAD is a microprocessor based high performance transmitter. It has flexible pressure calibration and output, automatic compensation of ambient temperature and process variables, configuration of various parameters, and communication with HART protocol. It measures pressure, flow and level by an application method. All data is input, modified and stored in EEPROM.

The KOBOLD Pressure Transmitter is also available as a flow meter. The flowmeter model PAD-F has an added totalizing function. It is able to check the flow rate and the totalizing flow. It measures the flow rate by using differential pressure without compensation for the temperature and static pressure. The shape of the PAD-F is the same as the standard device. Only the terminal block is different, since there are two more terminals for the display of the pulse output.

Electronics module

The Electronics module consists of a circuit board sealed in an enclosure. There is an MCU module. an analog module, an LCD module and a terminal module within the transmitter. The MCU module acquires the digital value from the analog module and applies correction coefficients selected from EEPROM. The output section of the MCU module converts the digital signal to a 4...20 mA output. The MCU module communicates with the HART -based configurator or control system such as DCS. The power section of the MCU module has a DC-to-DC power conversion circuit and an input/output isolation circuit. The LCD module plugs into the MCU module and displays the digital output in a user-configured unit.

Sensor Inputs

The models PAD-D, PAD-G, and PAD-H are available in a capacitance type differential pressure sensor. It measures differential and gauge pressure and is commonly used in flow and level applications. Both sides in the capacitance sensor transmit process pressure from the process isolators to the sensor. The model PAD-A is also available in a piezoresistive type absolute pressure sensor. The sensor module converts the capacitance or the resistance to the digital value. The MCU module calculates the process pressure based on the digital value.

The sensor modules include the following features

  • 0.075 % accuracy
  • The software of the transmitter compensates thermal effects, improving performance.
  • Precise Input Compensation during operation is achieved with temperature and pressure correction coefficients that are characterized over the range of the transmitter and stored in the sensor module EEPROM memory.
  • EEPROM stores sensor information and correction coeficients separately from MCU module, allowing for easy repair, reconfiguration and replacement.

Basic Setups

The following settings can be easily configured from any host that supports the HART protocol:

  • Operational parameters
  • 4-20 mA points (zero/span)
  • Engineering units
  • Damping time: 0.25...60 sec
  • Tag: 8 alphanumeric characters
  • Descriptor: 16 characters

  • Sensor zero trimming
  • Zero point adjustment
  • DAC output trimming
  • Transfer function
  • Self-compensation

Self-Diagnosis and others

  • CPU & Analog Module Fault Detection
  • Communication error
  • Fail-mode handling
  • LCD indication
  • Temperature measurement of sensor module

Multi Planar Process Connection

When the pressure transmitter should be vertically installed irrespective of the orientation of the process connection lines, modified fIanges (as shown above) are required in addition to the basic flanges. Multi- planar pressure transmitters have been made in an effort to solve the problems occurring in these types of installation. The object of this is to provide a pressure transmitter, capable of being vertically installed, without separate adaptors or various types of brackets. This is regardless of the position of the process connection lines.

Process Connection Via Diaphragm Seals

When connecting the differential pressure transmitter model PAD to all different process connections, diverse diaphragm seal versions are necessary. They can be connected to the differential pressure transmitter by direct mounting or via a capillary tube. Depending on the application, different combinations of diaphragm seals, capillary tubes and fill fluids are available. To clarify those options, the special connections via diaphragm seals sho
