1.2 Overview of Transmitter
Autrol® Smart Pressure Transmitter based in a microprocessor is the pressure transmitter, has a
designed capacitance sensor optimized for draft measurement. APT-3200 has a true draft analog
range from 0 to 20mA offering that feature that a pressure range or after convert analog range to
HART (Communication) digital signal transmit for control systems like DCS, PLC. This Model has
explosion protected type (Intrinsically Safety) and high precision, better reliability and is available on
digital communication for the use remotes communication system.
This transmitter is enabled in HART communication with Host, HHT (HART Hand-Held Terminal), PC
Configurator, or PDA Configurator. Thus, transmitter various variables in host is enable to be changed,
configured and tested calibrated by users. For the HART Communication between DC Power Supply of
24 Vdc and Transmitter has to terminate 250~ 550 Ohm as loop resistance by series connection.
1.3 Software Compatibility
Autrol® Smart Pressure Transmitter's software is implemented and complemented if necessary. Uses
of the transmitter will not be a compatibility software is contained in the host of the HHT(Model 275
HART Communicator). In this case contact us for software DD(Device Descriptor) to be able to use
with the transmitter, you must to use loading in HHT, etc.

2.1 Unpacking
When moving the transmitter to the installation site, keep it in its original packaging. Then, unpack
the transmitter there to avoid damage on the way.
2.2 Models and Specifications Check
The model name and specifications are indicated on the nameplate to the case. Please check your
specification and wanted model.
2.3 Storage
The following precautions must be observed when storing the instrument, especially for a long period.
(1) Select a storage area that meets the following conditions:
(a) It is not exposed to rain or water.
(b) It suffers minimum vibration and shock.
(c) If possible, it is preferable at normal temperature and humidity (approx. 25°C, 65% RH).
However, it has an ambient temperature and relative humidity within the following ranges.
● Ambient Temperature: -40 ~ 85°C (without LCD module)
-30 ~ 80°C (with LCD module)
*General Use -20 ~ 60°C (CSA Explosionproof)
● Relative Humidity: 5% ~ 98% RH (at 40°C)
(2) When storing the transmitter, repack it as nearly as possible to the way it was packed when
delivered from the factory.
(3) If storing a transmitter that has been used, thoroughly clean diaphragm surfaces (the pressure-
detector sections) of the diaphragm seals, so that no measured fluid remains on them. In addition,
make sure before storing that the pressure-detector and transmitter assemblies are securely
mounted.
2.4 Selecting Installation Locations
The transmitter is designed to withstand severe environmental conditions. However, to ensure stable
and accurate operation for many years, the following precautions must be observed when selecting an
installation location.
(1) Ambient Temperature
Avoid locations subject to wide temperature variations or a significant temperature gradient. If the
location is exposed to radiant heat from plant equipment, provide adequate insulation or
ventilation.
(2) Ambient Atmosphere
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a
corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion
or stagnation of rainwater in conduits. Moreover, there should be appropriate ventilation
preventing corrosion by rain gathered on conduit.

◈ Instrument installed in the process is under pressure. Never loosen or tighten the flange bolts as it may
cause dangerous spouting of process fluid.
◈ If the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact
with the body of inhalation of vapors even after dismounting the instrument from process line for
maintenance.
(3) Shock and Vibration
Select an installation site suffering minimum shock and vibration (although the transmitter is
designed to be relatively resistant to shock and vibration)
(4) Installation of Explosion-protected Transmitters
Explosion-protected transmitters can be installed in hazardous areas according to the gas types
for which they are certified.
(5) Select a place that transmitter maintenance is very easy.
2.5 Calibration on Spot after Installation
(1) Sensor Zero Trim should be done after transmitter is installed on spot, because zero point is not
accurate as to mounting status.
(2) For Sensor Zero Trim, make differential pressure of transmitter for zero in advance. Then, make
Sensor Zero Trim after pressure is sufficiently stabilized (after approximately 10 seconds).
(3) There are two ways for making differential pressure for zero. One is to apply zero differential
pressure (making same pressure both high and low side pressure). The other is to close High and
Low side of stop valve of 3 valve manifold and to open its equalizing valve.
(4) Sensor Zero Trimming is to use HHT (275 calibrator), PC or PDA configurator, and to use
Zero/Span button. Make sure all details on this manual.
(5) Refer to On-line Operation for configuring another parameters except Sensor Zero Trim
2.6 Pressure Connections
The following precautions must be observed in order to safely operate the transmitter under pressure.
(1) Never apply a pressure higher than the specified maximum working pressure.
(2) Confirm the option of pressure connection of transmitter. Necessarily use standardized and quality-
approved parts.
(3) In case of being needed by hard circumstances and regulations, there should be seal equipment
for leakage.
2.7 Waterproofing of Cable Conduit Connections
Apply a non-hardening sealant (silicone or tape, etc.) to the threads to waterproof the transmitter
cable conduit connections.
▲ Warning

www.autroltransmitter.com 10
◈ Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is
used near the transmitter of its external wiring, the transmitter may be affected by high frequency noise
pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from
the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the
transceiver outside the area affected by noise.
2.8 Restrictions on Use of Radio Transceivers
2.9 Insulation Resistance Test and Dielectric Strength Test
Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory
before shipment, normally these tests are not required. However, if required, observe the following
precautions in the test procedures.
(1) Do not perform such tests more frequently than is absolutely necessary. Even test voltages that do
not cause visible damage to the insulation may degrade the insulation and reduce safety margins.
(2) Never apply a voltage exceeding 500 Vdc (100 Vdc with an internal lightening protector) for the
insulation resistance test, nor a voltage exceeding 500V AC (100V AC with an internal lighting
protector) for the dielectric strength test.
(3) Before conducting these tests, disconnect all signal lines from the transmitter terminals. Perform
the tests in the following procedure.
(4) Insulation Resistance test
(a) Short-circuit the + and - SUPPLY terminals in the terminal box.
(b) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the
shorted SUPPLY terminals and the minus (-) lead wire to the grounding terminal.
(c) Turn ON the insulation tester power and measure the insulation resistance. The voltage
should be applied short as possible to verify that insulation resistance is at least 20MΩ.
(d) After completing the test and being very careful not to touch exposed conductors disconnect
the insulation tester and connect a 100kW resister between the grounding terminal and the
short-circuiting SUPPLY terminals. Leave this resistor connected at least three second to
discharge any static potential. Do not touch the terminal while it is discharging.
(5) Dielectric Strength Test
(a) Short-circuit the + and - SUPPLY terminals in the terminal box.
(b) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY
terminal and the grounding terminal. Be sure to connect the grounding lead of the dielectric
strength tester to the ground terminal.
(c) Set the current limit on the dielectric strength tester to 10mA, then turn ON the power and
gradually increase the tester voltage from '0' to the specified voltage.
(d) When the specified voltage is reached, hold it for one minute.
(e) After completing this test, slowly decrease the voltage to avoid any voltage surges.
