High accuracy pressure switches for middle-high pressure

The new PS97 series thin film pressure switch boasts a wide temperature range (-40~125 °C) and high accuracy of ±1 % F.S. (at 0~80 °C) with waterproof IP67 protection structure. Furthermore, wide variety of pressure range selections from 0 to 1.0 MPa, 2.5 MPa, 5.0 MPa, 10 MPa, 25 MPa, 40 MPa, 50 MPa, 80 MPa, suitable for a wide pressure range of middle-high pressure. The main target markets are machine tools, special vehicles, injection molding machines, high-pressure washing machines, and hydraulic equipment. We confirm and set Operation mode, Pressure set point for switching and Hysteresis you want before shipment.

UL recognized, CE marking applicable

Please tell us the pressure setting range etc. you want.

The PS97 series accepts the settings you wish with respect to the switch output, and we have registered the settings for the product at our factory and will ship it to you.
When purchasing, Please let us know your confirmation decisions below, assuming that you choose the rated pressure range in advance.

Select the switch output points [Required]: 1 or 2
Select the Operating Mode from the following two [Required]:

NO (Normally Open) :

Switch ON where the pressure has reached your any setting.

NC (Normally Closed):

Switch OFF where the pressure has reached your any setting.

*If you select the switch output of two points, you need to set it on each switch.
The following items are the same too.
The pressure setting range to operate switch you want; Set Point [Required]:
( MPa) ※Can be set to first decimal point

The Set Point must be within 3 to 97 % F.S. of the rated pressure range.
Do you want to set by your arbitrary about also Hysteresis? Reset Point [Optional]:
Yes ( % F.S.) or No

Hysteresis, that is, the Reset Point after the switch operation can be set at the rate you want. It must be set at 2 % F.S. or higher of the Set Point (above 3). If you do not wish to set the Reset Point at your arbitrary, we'll set up at 2 % F.S. of the Set Point by our discretion

*Refer to [Fig.1] below for the above confirmation.

Operating Precautions

The applicable media are gases/liquids compatible with SUS630. So please be careful about compatibility with applicable media. Use of corrosive fluid may cause injury and/or malfunction of products. In addition, the product is not explosive-proof. Never use flammable fluid as media.

Do not insert foreign materials, such as a wire, into the pressure port.Should this precaution be neglected, the characteristics may vary or the product may be damaged.

The sensor itself guarantees the operating temperature range from -40 to 125 °C, However sometimes the cable’s temperature range is less than the sensor’s one. Please use after confirming well.
(DT cable’s thermal withstand is 105 °C, M12 is 90 °C)

Do not insert foreign materials, such as a wire, into the pressure port. Should this precaution be neglected, the characteristics may vary or the product may be damaged.

Do not apply excessive force to the housing or the cables during the piping/wiring work. Should this precaution be neglected, the characteristics may vary or the product may be damaged.

Do not improperly connect the wires to the terminals. Should this precaution be neglected, the internal circuit may be damaged.

The mounting and dismounting must be carried out with the power switched off and at zero pressure.

The protective construction of the product is IP67. Do not use the product in an environment exceeding the IP67 rating. Should this precaution be neglected, there is a possibility of product failure.

Be sure to use a stable DC power supply source for the power supply unit. For protection of induction load of the relay or the solenoid, be sure to insert a surge-absorbing element (diode, varistor, etc.). For use of a power supply unit such as a switching power supply, be sure to provide an FG terminal.

Wires should be installed apart from the power line that handles high power as far as possible.

Please note that dew condensation due to sudden temperature transition, freezing within the pressure port (measurement of water pressure etc.) will cause malfunction.

Please handle the sealing surface and O-ring carefully so as not to scratch. The scratch may cause inferiority of sealing capability.

When using the optional connector cable, tighten fitting by hand after fully inserting the connector. If the tightening and inserting is inadequate, the product may fail to meet the specified IP.

In the insertion and removal of the connector, please check the direction with the product and connector grabbed tightly. Inadequate insertion and/or removal of the connector may cause product failure.

Please install it gently to the hexagon with a spanner (size: 22) matching the size and the maximum torque should be less than 35Nm. Be careful not to apply unnecessary force to the sensor body and cable at that time.

For use under the strong noise, consider shorting the sensor signal GND to the sensor body.

Standard O-ring material is NBR (-20~100 °C). Please be aware of the medium and the temperature.

Maintenance Precautions

Make sure the product operates normally before using. Unexpected event may cause product failure and affect its basic function.

Do not disassemble or modify the product. Unauthorized disassembly or modification may result in a malfunction. The product warranty does not cover failures caused by disassembly and/or modification ofthe product.

Stains on the product should be wiped off with a cloth immersed in a neutral detergent diluted water. Dry it with a soft cloth after they are wiped off. At this time, be careful not to allow the neutral detergent solution to enter the inside of the product. Infiltration of the neutral detergent solution may cause product failure.

M12 connector of optional is compliant to IEC61076-2-101. If you would like to use cable other than the optional cable, please make sure the cable is indeed in compliance with the proper standard. Some cables don’t meet IP standard, so please check it before using.

Warranty

The Warranty period for the product shall be one year. A failure due to causes attributed to design or manufacturing defects during the period one year from the date of delivery shall be repaired or replaced free of charge.
However, the following shall be excluded from the warranty:

Failure or damage caused by improper use and careless operation in violation of the Operating Instructions.
