Heavy Duty Differential Pressure Transmitter Model PAD

Description

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.

Transmitter Description

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 communicator 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 user­configured unit.

Heavy Duty Differential Pressure Transmitter Model PAD

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

• 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
coefficients 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

• Message: 32 Characters

• Date: Day/Month/Year

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 flanges
(as shown above) are required in addition to the basic flanges. Multi­planar 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 adapters or various types of brackets.
This is regardless of the position of the process connection lines.

Calibration and Adjustment

• Lower/Upper Range (Zero/Span)

• Sensor Zero Trimming

• Zero Point Adjustment

• DAC Output Trimming

• Transfer Function

• Self-Compensation

No responsibility taken for errors;
subject to change without prior notice.

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 should be specified separately for
the differential pressure transmitter.
