1 EQUIPMENT DESCRIPTION
VPT10-H is a transmitter for differential, absolute or gauge pressure, level or flow measurements with HART
®
technology, which integrates Vivace Process Instruments family of field devices.
The transmitter features intelligent, microprocessor-based capacitive sensor for safe operation and excellent field
performance. It has integrated pressure and temperature compensations, providing high performance and stability
of measurements.
VPT10-H must be powered by a voltage of 12 to 45 Vdc in order to generate a 4-20 mA current channel (according
to NAMUR NE43) proportional to the measurement performed.
Its configuration uses HART
®
7 communication protocol, already recognized as the most used in the world of
industrial automation for configuration, calibration, monitoring and diagnostics, and can be performed by the user
with the use of a HART
®
configurator or EDDL
®
or FDT/DTM
®
-based tools. In addition, the main parameters can be
set via local adjustment using a magnetic tool.
VPT10-H intelligent pressure transmitter is factory calibrated before shipment to customers. If it is necessary to
recalibrate this transmitter in the field, be sure to use a calibrator at least three times more accurate than the
specifications. To ensure correct and efficient use of the transmitter, please read this manual before installation.
1.1. BLOCK DIAGRAM
The modularization of the transmitter components is described in the following block diagram.
Figure 1.1 –VPT10-H block diagram.
The main board controls the main functions of the pressure transmitter. It contains a HART
®
Modem and a
microcontroller (CPU). The sensor board is responsible for reading the capacitance of the capacitive sensor, as well
as the temperature and its processing with the main CPU.
The HART
®
modem block interfaces the microcontroller signals with the HART
®
line to which the transmitter connects.
The display board has the controller block that interfaces between the LCD and the CPU, adapting the messages to
be displayed.
Finally, the microcontroller block can be related to the transmitter's brain, which manages all the time controls, HART
®
state machines, diagnostics and routines common to transmitters, such as configuration, calibration and generation of
the digital output value for current, proportional to the PV variable.

1.2. CAPACITIVE SENSOR
The pressure sensor used by VPT10-H pressure transmitter is capacitive (capacitive cell), shown schematically in
figure 1.2.
Figure 1.2 – High performance capacitive sensor.
See figure 1.3, below, to understand the working principle of the capacitive sensor.
Figure 1.3 – Principle of operation of the capacitive sensor.
The core of the capacitive sensor is the central diaphragm. There are two measuring capacitances (CH and CL),
according to the position of this diaphragm. These measuring capacitances share the central diaphragm (movable
plate) and the other plate is attached to both sides of the sensor.
When the pressures on both sides are equal, the diaphragm is in the center and the capacitances on both sides are
the same. However, when the pressure on the high pressure side (CH) is greater than the pressure on the low pressure
side (CL), for example, the filling fluid will move, causing the diaphragm to move to the low pressure side . As a result,
the capacitance on the high pressure side will be lower than the capacitance on the low pressure side.

However, when the differential capacitance structure is used, the distance between CL and CH plates has a linear
variation with the relation between the difference and the sum of the measured capacitances.
When the displacement of the central diaphragm is inferior than its thickness, there will be a linear relationship between
this displacement and the differential pressure. That is, if the differential pressure (∆P) applied to the capacitive cell
does not deflect the sensor diaphragm beyond d/4, we can assume that ∆P will be proportional to ∆d.
In short:
P1 and P2 are applied pressures on the high and low pressure sides (H and L), respectively.
CH = capacitance on high pressure side, measured between P1 fixed plate and the central diaphragm.
CL = capacitance on low pressure side, measured between P2 fixed plate and the central diaphragm.
d = distance between the fixed plates of CH and CL.
∆d = deflection of the central diaphragm due to the application of the differential pressure ∆P = P1 - P2.
The capacitance of a capacitor of flat and parallel plates can be expressed as a function of the area (A) of the plates
and the distance (d) separating them as:
, where ϵ= the dielectric constant of the medium between the capacitor plates.
If we consider CH and CL as capacitances of flat plates of the same area and parallel, when P1> P2 we have:
On the other hand, if the differential pressure (∆P) applied to the capacitive cell does not deflect the sensor diaphragm
beyond d/4, we can assume ∆P proportional to ∆d.
If we develop the expression (CL-CH) / (CL+CH) we get:
As the distance (d) between the fixed plates of CH and CL is constant, the expression (CL-CH) / (CL+CH) is
proportional to Δd and therefore to the differential pressure to be measured.
Thus, it is concluded that the capacitive cell is a pressure sensor composed of two capacitors of variable capacitances,
according to the applied differential pressure.
These capacitors are part of an oscillator circuit that has its frequency dependent on the applied differential pressure.
This frequency will be inversely proportional to the applied pressure and is measured by the CPU of the pressure
sensor with high resolution, accuracy and processing speed.

1.3. OPERATING PRINCIPLE
The main circuit of VPT10-H receives the capacitance readings (CL and CH) and temperature from the analog sensor
board. The normalized pressure signal is calculated by applying the factory compensation polynomial to the CL and
CH readings. From this value, using the sensor reading range, the pressure in the user unit (configurable) is calculated
with the relevant calibrations of zero, maximum pressure and minimum pressure.
Depending on the sensor range, user can choose the form of treatment for the pressure value: Linear, Table, Square
Root Extraction (single, triple or quintuple) or the combination between Table and Square Root Extraction. With the
option of Table, it is possible to mount a custom curve of up to 16 points, mainly used with the characterization of
volumes in tanks. The Square Root Extraction is used in the application of the mass and flow measurement transfer
function.
Figure 1.4 – Operating principle of VPT10-H.
VPT10-H still provides the ambient temperature reading as a secondary variable and the pressure reading as a tertiary
variable (even if the primary variable is set as flow measurement).
The primary variable (PV) can be configured to indicate pressure or flow according to the configured transfer function
(Linear and Table for Pressure, Square Root Extraction for Flow).
According to the type of variable to be indicated, user can also configure unit, work range, limits and alarms (for
pressure and flow, separately).
In addition, the transmitter can calculate the Totalization, considering the flow rate, according to the unit configured by
user (mass or volume in time). It is possible to reset the Totalization, enable/disable it and also set a limit value so an
alarm can be generated.

The following precautions should be observed when storing the equipment, especially for a long period:
(1) Select a storage area that meets the following conditions:
a) No direct exposition to rain, water, snow or sunlight.
b) No exposition to vibration and shocks.
c) Normal temperature and humidity (around 20°C / 70°F, 65% RH).
However, it can also be stored under the following temperature and humidity intervals:
●Ambient Temperature: -40°C to 85°C (without LCD)* or -30°C to 80°C (with LCD)
●Relative Humidity: 5% to 98% RH (@ 40°C)
(2) For equipment storage, use original factory package (or similar).
(3) If storing an already used Vivace equipment, dry every moist part and clean all connections that
was in contact with the process. Keep covers and connections closed and properly protected for its
specific application and requirements.
