Section 1 General information
1.1 Introduction
MSP80 pressure transmitter with digital technology, perfect assembly process and welding technology
assures the high performance and reliability.
Apart from the remote communication, rerange and zero adjustment can be realized via local keys, user-selectable
for linear or square root output can be calibrated using software. Transmitter can self-monitoring and
self-diagnostic without disrupting in the measurement systems, which digital HART protocol are superimposed on
the 4 to 20 mA analog signal.
User can choose process wetted parts material to meet different corrosion-resistant requirement on the installation
location.

Section 2 Installation
2.1 Overview
Measurement accuracy depends upon proper installation of the transmitter and impulse piping. Mount the
transmitter close to the process and use a minimum of piping to achieve best accuracy. Keep in mind the need for
easy access, personnel safety, practical field calibration, and a suitable transmitter environment. Install the t
ransmitter to minimize vibration, shock, and temperature fluctuation.

2.2 Mechanical considerations
Liquid Measurement.
Place taps to the side of the line to prevent sediment deposits on the transmitter process isolators.
Mount the transmitter beside or below the taps so gases can vent into the process line.
Mount drain/vent valve upward to allow gases to vent.
Gas Measurement.
Place taps in the top or side of the line.
Mount the transmitter beside or above the taps so liquid will drain into the process line.
Steam Measurement.
Place taps to the side of the line.
Mount the transmitter below the taps to ensure that the impulse piping will stay filled with condensate,
Fill impulse lines with water to prevent the steam from contacting the transmitter directly.
The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate
measurements.
There are five possible sources of error: pressure transfer, leaks, and friction loss (particularly if purging is used),
trapped gas in a liquid line, liquid in a gas line, and density variations between the legs.

Resistance
250...1500Ohm
Power Supply
12...45V DC
Use the following steps to wire the transmitter:
a) Remove the housing cover on the back side.
b) Connect the positive lead to the “+” terminal and the negative lead to the “–” terminal. Pull cables through
cable gland
c) Perform the connections following the wiring diagram
It is important that the instrument cable shield:
• be trimmed close and insulated from touching the transmitter housing
• be connected to the next shield if cable is routed through a junction box
• be connected to a good earth ground at the power supply end
d) Close the cover and refasten the screws.
Ensure proper grounding.Installation of the transient protection terminal block does not provide transient
protection unless the MSP80 case is properly grounded.

Operating manual MSP80
The best location for the transmitter in relation to the process pipe depends on the process itself. Use the
following guidelines to determine transmitter location and placement of impulse piping:
1. Keep impulse piping as short as possible.
2. For liquid service, slope the impulse piping at least 1 inch per foot (8 cm per m) upward from the transmitter
toward the process connection.
3. For gas service, slope the impulse piping at least 1 inch per foot (8 cm per m) downward from the transmitter
toward the process connection.
4. Avoid high points in liquid lines and low points in gas lines.
5. Make sure both impulse legs are the same temperature.
6. Use impulse piping large enough to avoid friction effects and blockage.
7. Vent all gas from liquid piping legs.
2.3 Power Supply
The transmitter requires power supply between 12 and 45V dc, power supply should provide power with less than
2% ripple.
Max. Loop Resistance = 50 x (Power Supply Voltage-12) Ohm
HART Communication requires loop resistance between 250 to 1500 ohms, With stand 24 V DC supply, loop
resistance 250-600 ohm can be used.
2.4 Wiring
1. Terminal block wiring diagram
Power supply and output terminal
Test
External indicator (ammeter) terminal*1*2
Ground terminal
Transmitter terminal box is in the compartment of the electronics housing, Remove the cover, signal wiring
terminals are attached above the test terminal.
Do not connect the powered signal wiring to the test terminals.
Power could damage the test diode in the test connection. If this occurs, Short-circuit the test terminals in the
terminal box,transmitter will power normally again. Use shielded twisted pairs to yield best results. In order to
ensure proper communication, Installed signal wiring should not be run together, should not be in the same cable
tray as AC power wiring or near heavy electrical equipment.
Plug and seal unused conduit connections on the transmitter housing to avoid moisture accumulation in the
terminal side of the housing. If you do not seal the unused connections, mount the transmitter with the electrical
housing positioned downward for drainage.
Never apply a voltage exceeding 500 V DC (100 V DC with an internal lightning protector) for the insulation
resistance test.
