SYMBOLS

This mark indicates precautions that must be taken
if there is danger of electric shock, fire, etc., which
could result in loss of life or injury.

This mark indicates that if these precautions and
operating procedures are not taken, damage to the
instrument may result.

This mark indicates that all precautions should be
taken for safe usage.

This mark indicates important information on
installation, handling and operating procedures.

This mark indicates supplemental information on
installation, handling and operating procedures.

This mark indicates where additional information
may be located.

An external protection device must be installed if failure

of this instrument could result in damage to the
instrument, equipment or injury to personnel.

All wiring must be completed before power is turned on

to prevent electric shock, fire or damage to instrument
and equipment.

This instrument must be used in accordance with the

specifications to prevent fire or damage to instrument
and equipment.

This instrument is not intended for use in locations

subject to flammable or explosive gases.

Do not touch high-voltage connections such as power

supply terminals, etc. to avoid electric shock.

RKC is not responsible if this instrument is repaired,

modified or disassembled by other than
factory-approved personnel. Malfunction can occur and
warranty is void under these conditions.

This product is intended for use with industrial machines, test

and measuring equipment. (It is not designed for use with
medical equipment and nuclear energy.)

This is a Class A instrument. In a domestic environment, this

instrument may cause radio interference, in which case the user
may be required to take additional measures.

All precautions described in this manual should be taken to avoid

damage to the instrument or equipment.

All wiring must be in accordance with local codes and regulations.

Tighten each terminal screw to the specified torque found in the

manual to avoid electric shock, fire or malfunction.

Remove resin adhered to the instrument with dry cloth before the

resin hardens. Take caution to avoid being burned.

Tools such as wire wheels or abrasive cloths should never be

used to clean the process diaphragm.

Dropping the instrument may cause the sensor to break or

malfunction.

To protect built-in precision components from damage, handle and

install carefully. Take care to avoid damage to the diaphragm.

Do not wipe or rub the nameplate on the outer case of the resin

pressure sensor with a cloth moistened with an organic solvent, or
a glove. If so, the printed section may be erased.

This product uses stainless steel, aluminum, and fluororesin (O-rings

and leadwire covering materials). When disposing of each part used
for this product, always follows the procedure for disposing of industrial
wastes stipulated by the respective local community.

If the output from the resin pressure sensor is found to be

abnormal during the operation, immediately stop the operation and
inspect for any distortion or damage of the diaphragm. If the
diaphragm is damaged, the pressure of the measured media
(e.g.resin) is applied to the inside of the resin pressure sensor.
Continued use under such conditions may result in the damage of
the screw which fixes the folder in the housing, and the folder in
the housing may come off in the worst case.

Do not use the pressure sensor in stead of a blind bolt.

NOTICE

This manual assumes that the reader has a fundamental knowledge

1. OUTLINE

Great features

•

As its lead pipe and pressure sensing blocks have a triple

construction output indication changes caused by external transient
temperature variations are extremely small. In addition, the
attachment of a lead pipe cover (optional) further restricts small
output indication changes.

•

As the sensor uses the push rod method, resin contamination is

prevented for the sensor damage.

•

High accuracy of the measured pressure can be achieved when the

instrument is used in conjunction with an output converter having
linearizing function (PCT-300) or a pressure indicator (PG500 or
REX-PG410). However, excluding the sensor having pressure
range (70 MPa or more) and a HASTELLOY C diaphragm.
