Important Safety Instructions
<Symbols in This Operation Manual>
Warnings and cautionary notes are provided in this manual to ensure this product is used correctly and to
prevent personal injury and property damage. The meanings of the WARNING and CAUTION symbols in
this manual are as described below. Read and understand these notes before reading the rest of this
manual.
Specific Warnings
When mounting connector parts, comply with the
instructions issued by each connector manufacturer.
Loose connections may result in disconnection or
chemical leakage. The use of dangerous chemicals,
solvents, and gases may cause physical impairment.
Do not use the product in areas where corrosive gases are
being ejected. Corrosion in the pressure sensor and
connector may result in liquid leakage. The use of
dangerous chemicals, solvents, and gases may cause
physical impairment.
Obey these instructions.
- Refrain from excessive tightening of the connector parts.
- Do not install the product in areas of excessive vibration
or shock.
- Use the product only within the specified operating
environment. Otherwise, damage to the pressure sensor
and connector may occur and result in liquid leakage.
The use of dangerous chemicals, solvents, and gases
may cause physical impairment.
Protect all wiring used by providing support along the
wiring at appropriate distances.
For shielded cables, peel the sheath at the very end of the
cable and connect the shield to the chassis or mounting
plate, etc., using the proper tool (recommended tool: Nitto
Supply AL-2).
WARNING
This product is not explosion-proof. Never use it with
flammable fluids such as solvents. Doing so may cause
fire and or explosion and is highly dangerous.
Never disassemble or alter the product.
Doing so will cause breakage of the product and possible
liquid leakage. The use of dangerous chemicals, solvents,
and gases may cause physical impairment.
Do not apply more pressure than the allowed maximum
output. Doing so will cause product failure and possible
liquid leakage. The use of dangerous chemicals, solvents,
and gases may cause physical impairment.
Do not insert screwdrivers, wires, or other objects into the
connector parts. Doing so will cause product failure and
possible liquid leakage. The use of dangerous chemicals,
solvents, and gases may cause physical impairment.
Refrain from excessive pulling or bending of the cables.
Doing so may cause wiring disconnections, which may
cause electrical shock and fire hazards.
Install the pressure sensor in an area that is dry and
clean. Supply power to the pressure sensor from an
isolation transformer (switching power supply) rated for 24
VDC or less. Make sure the rated power output is 150 VA
and does not exceed 2A. (Use exclusively for class 2
circuits)

Product Description
<Applications>
PTFE Pressure Sensors can be used as semiconductor manufacturing devices or as pressure
monitor/process control devices for chemical processes, high-purity fluids, etc.
<Features>
●All models comply with the RoHS directive.
●The wetted part is fully made of fluorine resin allowing it be used with a variety of chemicals.
●Because the Pressure Sensors use strain gauges, they offer you excellent reliability and durability.
●Zero adjust is also possible by remote control using the External Zero Adjust function.
●A green LED indicator is provided on top of the case for easy recognition of power-on status (lit), and
zero adjust (flashing).

Mounting and Connecting the Connector Parts
When connecting the connector parts, clamp the sides of the body (WAF: 32 mm) with the dedicated tool
for the connector, and tighten the connector while preventing the body from turning.
In order to install connector parts correctly, always refer to the relevant catalog or operation manual issued
by the connector manufacturer.
Points to Observe When Installing
To prevent erroneous operation or premature wear, do not install in:
When mounting connector parts, comply with the instructions issued by each
connector manufacturer. Loose connections may result in disconnection or
chemical leakage. The use of dangerous chemicals, solvents, and gases
