Instruction Manual
Compact Pressure Sensor
PSE540 / PSE541 / PSE543
The intended use of the pressure sensor is to measure the pressure of
fluids and provide an analogue output signal.
1 Safety Instructions
These safety instructions are intended to prevent hazardous situations
and/or equipment damage. These instructions indicate the level of
potential hazard with the labels of “Caution,” “Warning” or “Danger.”
They are all important notes for safety and must be followed in addition
to International Standards (ISO/IEC)*1), and other safety regulations.
*1) ISO 4414: Pneumatic fluid power - General rules relating to systems.
ISO 4413: Hydraulic fluid power - General rules relating to systems.
IEC 60204-1: Safety of machinery - Electrical equipment of
machines. (Part 1: General requirements)
ISO 10218-1: Manipulating industrial robots –Safety, etc.
•Refer to the product catalogue, operation manual and handling
precautions for SMC products for additional information.
•Keep this manual in a safe place for future reference.
•To ensure safety of personnel and equipment the safety instructions
in this manual must be observed, along with other relevant safety
practices.
Caution indicates a hazard with a low level of risk
which, if not avoided, could result in minor or
Warning indicates a hazard with a medium level
of risk which, if not avoided, could result in death
Danger indicates a hazard with a high level of risk
which, if not avoided, will result in death or
Warning
•Ensure compliance with relevant safety laws and standards.
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.

3 Installation
Warning
Do not install the product unless the safety instructions have been read
and understood.
3.1 Piping Caution
•Before piping make sure to clean up chips, cutting oil, dust etc.
•When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1.5 to 2 threads
exposed on the end of the pipe/fitting.
•Tighten fittings to the specified tightening torque.
1/4 rotation after tightening by hand
1/6 rotation after tightening by hand
•Only fluids which are non-corrosive to SUS303, C3604BD, and NBR
should be used.
•Install the piping correctly in a safe place away from water and dust.
•When piping, apply a spanner to the piping section of the sensor.
•For one touch fittings, insert the tube into the sensor fitting carefully
and securely all the way to the bottom.
3.2 Environment Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•Do not use in an explosive atmosphere.
•Do not expose to direct sunlight. Use a suitable protective cover.
•Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result
in temperatures in excess of the product’s specifications.
4 Wiring
4.1 Internal circuit and wiring
•Output specification
Voltage output: 1 to 5 V
Output impedance: Approx. 1 kΩ
4.2 Attaching a sensor connector to the lead wire
•The sensor wire sheath should be stripped as shown in the figure.
•Do not cut the insulation.
•The corresponding wire colour shown in the table should be pushed
fully into the correct pin number marked on the sensor connector.
Pin No. Wire colour
•Check that the above preparation has been performed correctly, then
press part A by hand to make a temporary connection.
•Press part A fully home using a suitable tool.
•The sensor connectors cannot be re-used once they have been
pressed fully closed. If connection failure or incorrect wiring occurs a
new sensor connector must be used.
•When connecting the sensor to a PSE200 / PSE300 series monitor,
use the connector for sensor lead wire (ZS-28-C) or an e-Con*
connector from the table below.
* Refer to the manufacturers e-Con connector catalogue.
