Chapter 1: Installation
1.1 Introduction
The HygroPro moisture transmitter is a compact,
intrinsically-safe, loop-powered, 4-20 mA transmitter
that provides accurate dew/frost point measurements
over a range of –110° to 20°C (-166° to 68°F). It features an
integrated display and a six-button keypad, and it is
housed in an IP67/Type 4X enclosure.
The HygroPro transmitter uses an aluminum oxide
moisture sensor, and it includes a temperature thermistor
and a pressure transducer on a common mount for
calculation of parameters such as:
• ppmvin gases
• ppmwin liquids
• pounds per million standard cubic feet
in natural gas
• process relative humidity.
IMPORTANT
To install the HygroPro in a hazardous (classified) area,
see "Hazardous area wiring connections" on page 6.

1.2 Sample system guidelines
The HygroPro transmitter can be installed in a sample
system or directly in the process line. However, Panametrics
recommends that the unit be installed in a sample
system to protect the probe from potentially damaging
components in the process stream. Figure 1 below
shows a typical sample system.
HygroPro
Probe
Needle
valve 1
Needle
valve 2
Flow cell
Flow
See note below
Intake near the center of the
pipe is recommended.
Figure 1: A typical sample system
Note: At least 5 ft (1.5 m) of 1/4” (6 mm) tubing vented
to atmosphere will ensure an accurate process sample
and avoid diffusion of ambient air moisture back into
the process.
In the sample system shown in Figure 1 on page 2,
fully open valve 1 and use valve 2 to regulate the sample
flow for measurements at process system pressure.
For measurements at atmospheric pressure, fully open
valve 2 and use valve 1 to regulate the sample flow.
Before constructing a sample system, consult a Panametrics
application engineer and observe the following guidelines:
• The sample system should be very simple and should
contain as few components as possible. All or most of
those components should be located downstream
of the measurement point.
• Sample system components must not affect moisture
readings. Most common filters and pressure regulators
are not suitable for sample systems because the wetted
parts adsorb moisture or release moisture into the sample
system. They may also allow ambient contamination to
enter the sample system. If possible, use stainless steel
for all wetted parts.
• The HygroPro probe should be oriented perpendicular
to the sample system inlet. For dimensions and
other sample system requirements see "Mechanical
specifications" on page 19.
• Sample systems should be tested for leaks prior to
operation, using a Snoop leak detector, to verify the
integrity of connections, components and fittings.
IMPORTANT
When pressurizing or depressurizing the sample system,
be careful to avoid shock damage to the moisture sensor.

1.3 Mounting the transmitter
CAUTION!
If the HygroPro will be installed directly
into the process line, consult Panametrics
for proper installation instructions and
precautions before proceeding.
Refer to Figure 2 below and complete the steps on the next
page to install the HygroPro transmitter.

Figure 2: HygroPro installation
1. Make sure the sintered or stainless-steel shield is in
place over the sensor. This shield protects the aluminum
oxide sensor from damage during operation.
2. Using the integral 3/4-16 straight male thread, screw the
probe end of the transmitter into the process or sample
system fitting. Make sure not to damage the threads.
Note: A 3/4-16 to G 1/2 thread adapter is available from
Panametrics.
3. Using a 1-1/8” wrench on the probe hex nut, tighten the
probe securely into the process or sample system fitting.
CAUTION!
Do not apply torque to the transmitter
electronic module to tighten the unit into its
fitting.
Note: If there is insufficient space to rotate the HygroPro
during installation, remove the replaceable transducer
element (RTE) from the transmitter, install it in the fitting,
then re-install the the transmitter onto the RTE.

1.4 Wiring the transmitter
Proceed to the appropriate section for instructions on:
• Standard wiring connections (below)
• "Hazardous area wiring connections" on page 6
1.4.1 Standard wiring connections
The HygroPro is a 4-20 mA loop-powered device that can
use the same two wires for its measurement signal lines
and its power supply lines. Follow the instructions in this
section only for units not requiring hazardous (classified)
area protection.
IMPORTANT
To install the HygroPro in a hazardous (classified) area, see
"Hazardous area wiring connections" on page 6
The transmitter must be wired using the factory-supplied,
2-meter cable. If a different cable length is required, please
contact the factory for assistance.
Note: If a longer cable is required, you may splice an
extension onto the standard cable. Be sure to connect
leads of the same color together. For example, connect blue
lead to blue lead, brown lead to brown lead, etc.
The HygroPro may be connected to either of the following
types of external systems:
• an external device that can provide the loop power
to the HygroPro and can also receive and display the
4-20 mA measurement output from the HygroPro
(proceed to next page)
• an external power supply to provide power to the
HygroPro plus a personal computer (PC) running
Panametrics’ PanaView™ interface software

• an isolated, intrinsically-safe, 24 VDC power supply
mounted in the safe area
• an isolated zener barrier mounted in the safe area
and installed between a standard 24 VDC power
supply and the HygroPro
Refer to "Figure 6" on page 8 for a typical hazardous
(classified) area HygroPro wiring diagram. This installation
uses an MTL706 zener barrier, in accordance with the
second option listed above.
If using serial communications with a PC, an isolated
RS232-RS485 converter mounted in the safe area between
the computer and HygroPro must be used. The converter is
typically powered by its own standard 24 VDC power supply.
WARNING!
Do NOT power an RS232-RS485 converter
from the same intrinsically-safe 24 VDC
power supply used to power the HygroPro.

1.4.2e Special conditions for safe operation
The “X” at the end of the HygroPro ATEX certificate number,
Bas06ATEX0019X, indicates that special conditions are
required for safe operation in Europe. These conditions are:
1. The equipment must be protected against impact or
friction with ferrous metals.
2. The bare ends of the connecting cable must be
terminated in such a way that the terminations are
afforded a degree of protection of not less than IP20
ingress protection.
3. The HygroPro is incapable of withstanding the
500 VAC test between all inputs and frame for one
minute. Therefore, the HygroPro must be earthed by
connecting the outer grounding screw on the HygroPro
with the equipotential bonding system. Follow the
local standards and electrical codes regarding the
equipotential bonding system.
WARNING!
Never connect or disconnect the HygroPro in
the hazardous area when supply power or the
communication circuit is energized. Isolate
the supply lines in the non-hazardous area
first.
Following the same special conditions listed above is
recommended for regions outside of Europe as well.
