Easy to use

New features include the easy to clean,

clog resistant structure and a highly visible

indicator and display. In combination with

its intuitive operation, the GP-M provides the

next level of ease-of-use functionality.

Its hex-shaped design, rotatable display, and

user-friendly setup simplify the installation.

With six different models available, the

GP-M can be used for almost any pressure

application. Its standard footprint for all

models simplifies integration.

Inverse display functionThe digitial display can be inverted 180 degrees, which allows installation in nearly any orientation.

Prevent unauthorized changesKey Lock and Password Protection settings are available to prevent unauthorized changes from being made.

Easy MaintenanceClogging inside of the sensor may lead to a delayed response or errors in detection values. The GP-M can be removed and cleaned when couplings or other connecting parts become clogged. The step flush diaphragm design simplifies debris removal.

Conventional: Bourdon tube & Mechanical type・Values are difficult to understand

A P P L I C AT I O N S

With its wide pressure range, from -14.5 to +5802 PSI (−0.1 to +40 MPa), and ceramic (alumina) diaphragm with high oil resistance, the GP-M Series can inspect pressure in a variety of applications.

The step flush diaphragm, with its small indentation inside of the sensor, prevents liquid and bubbles from easily clogging the pipe. In addition, it is easy to remove this sensor for cleaning. Users should consider the GP-M Series for fluids that commonly result in clogging.

The GP-M Series can monitor fluids between -20 and +100°C -4 and +212°F and can therefore be used in a wide variety of applications ranging from cooling, heat retention, and sterilization. (Ensure that the environment is free from freezing or condensation.)

Free range analog Hold function

Window mode (Fno/Fnc)

Pressure is likely to fluctuate from factors such as pressure spikes. This mode allows for free adjustment of hysteresis in order to prevent chattering due to fluctuating pressure.

The data is output within the range of 4 to 20 mA in correspondence with the upper and lower limit values of the required pressure range. The pressure range can be adjusted as desired to maximize resolution.

This function displays the peak value and bottom value measured since the GP-M Series was turned on. Users can check the peak and bottom values easily by quickly pressing the ▲ or ▼ button while pressing the MODE button.

This mode is used to judge whether or not a measurement value is inside or outside of a specified zone.

Assume that SP-rP = Hysteresis

The mode turns ON when a measurement value rises above SP.

The mode turns ON when a measurement value rises above FL + Hysteresis.

The mode turns OFF when a measurement value rises above FH.

The mode turns ON when a measurement value falls below FH – Hysteresis.

The mode turns OFF when a measurement value falls below FL.

The mode turns OFF when a measurement value falls below rP. 2 3

Other precautions

Do not use this product for the purpose of protecting a human body or a part of human body.

This product is not intended for use as an explosion-proof product. Do not use this product in hazardous locations and/or potentially explosive atmospheres.

The GP-M Series is not designed to sanitary specifications. Do not use the product for applications such as drinks, foods, or medical liquids.

Do not use the GP-M Series for applications requiring safety measures, such as any nuclear, railroad, aircraft, vehicle, orplayground equipment.

The power ON reset time for the GP-M Series is 2 seconds after power is turned on. Do not use outputs from the sensor during this period.

Initial drift may occur after supplying power to the GP-M Series. To detect a minute difference in the pressure, let the GP-M Series warm up for approximately 15 to 30 minutes.

Do not bring a strong magnet or magnetic field close to the main body of the GP-M Series.

Do not remove the seal of the air hole of the GP-M001/M010/M025. It will no longer be waterproof.

When conducting maintenance, use a soft brush so as not to damage items such as the detection surface or the O ring.

When replacing the O ring, clean all of the debris from the surface that will be in contact with the O ring.

Condensation may cause measurement failure or breakage. To prevent this, take the following measures:• Make sure the ambient temperature is same as the fluid temperature or less.

• Use an A/C for dehumidification.• Keep the cooling pipe away from the sensor by 30 cm 11.81" or more using a connecting pipe.

The recommended ambient temperatures and relative humidities are within the highlighted area of the graph below.

The recommended tightening torque when installing the adapter to the main body of the sensor is 20 N•m. It is recommended to apply grease to the G3/4 threaded part in order to avoid thread damage.

• Regardless of whether the power of the device is ON orOFF, do not touch the main part of the pressure detector. If the pressure detector is touched, damage may occur due to static electricity.

• If using a non-conductive liquid such as oil with plastic piping, the risk of an offset changewill become greater. In such a case, it is recommended to ground the metal housing.

• In the case that noise causes malfunction, grounding the metal housing may improve performance.• After installation, conduct an atmospheric correction by making the applied pressure the same as

regular room pressure.• When condensation occurs on piping, place the cooling pipe away from the sensor by 30 cm 11.81"

or more using a connecting pipe.

The metal parts of the main body and the internal circuits are 0 V insulated.

You must verify that the GP-M Series is operating correctly in terms of functionality and performance before the start and operation of the GP-M Series.

We recommend that you take all the necessary safety measures to avoid any damage in the unlikely event of a problem occurring.

Do not use the GP-M Series with corrosive liquids.

We cannot guarantee the functions and/or performance in the event that the product is used outside the standards of the specification, or if the product is modified.

When using our product in combination with another product, based on such factors as conditions of use and surrounding environment, sometimes functions and performance may not be fully realized. In such a case, use after adequate examination.

Piping

• Use the adapter to match the diameter of the piping.• When using the adapter, fit the O ring attached to the main body

to the screw threads of the Adapter G3/4. (Refer to the diagram below.)

• When using a self-made adapter instead of the optional adaptor, or when attaching the main body directly to piping or the tank, specific steps are needed in order to fit the GP-M Series and O ring to the equipment. Please contact KEYENCE for details.

• The body may be rotated horizontally to 330°. When rotating, hold the clasp in place with a wrench.

CAUTION

CAUTION

CAUTION

When detecting the temperature of the fluid, the housing of the product will be hot, and there is the danger of a burn injury. Do not touch the metal housing while the product is in operation.

The screw part of the main unit is sharp, take care to avoid injury.

Do not drop or hit the device, and avoid any other large shock to the device.

Do not use a sharply pointed object to press the setting keys.

If the detection portion is pushed with a sharp object, damage may occur to the detection surface. Also, for devices where the measuring range is low, the detection portion is thin and easy to break. Touch as little as possible.

FD-M Series

LOWERS MAINTENANCEDramatically reduces cloggingUnlike general floating element and paddle wheel flow meters, the FD-M Series has a "free flowing structure" that is completely free of moving parts and obstructions. There is no trouble with dirt and rust clogging the mechanical parts, greatly reducing maintenance.

LONG L IFESPANNo damage from moving partsDue to the absence of moving parts, it does not experience axial wear or other types of mechanical wear. Through its “free flowing structure” the FD-M Series has achieved a significantly longer lifespan.

ENERGY SAVINGDramatically reduces pressure lossDue to its “free flowing structure”, the FD-M Series has almost no pressure loss. Does not apply a large load on pumps and thus saves energy.

*1 Twice the rated flow range can be displayed.
