FM4000 overview
FM4000 is a component documented by TOKYO KEISO CO.,LTD. The PDF description identifies it as "FM4000 Sep 2025." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.
Datasheet snapshot
- Manufacturer: TOKYO KEISO CO.,LTD.
- Part number: FM4000
- Category: IC
- Datasheet length: 21 Pages
Key features noted in the PDF
- Refer to the detailed diagram of the support on page 6 for the dimensions of the support. (55) H EC H/2 Support H≥2500 Seat ： 1.5 Spiral ： 3.3 10K, #150 class ： 17.6 20K, #300 cla.
- A support is provided when the face-to-face dimension is 2,500 mm or longer.
- The support material is 304SS.
- Mounting holes on a support are designed for M16 bolts. When M16 bolts are not applicable, M12 bolts can be used instead with plain washers of 12 nominal diameter.
- Standard: Left-side mounting
- When the gauge comes with a scale plate, the flapper indication color is yellow only at every 10 mm.
- For using a capacity scale plate, a tank table is required to see both capacity and liquid level. Indicator Indicator window acrylic : A single indicator can cover the measurement.
Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Alarm switches and/or analog output (4 to 20 mA DC) transmitters can be additionally provided for on-site checking and remote monitoring and control purposes.
- Contact us for details. ❏ High-performance analog output (4 to 20 mA DC) transmitter using magnetostrictive effect High-precision analog output (4 to 20 mA DC) transmitter using the magnetostrictive effect can be additionally provided.
- In an indicator unit, rotating flappers made of plastic magnets are arranged at every 10 mm.
- The front surfaces of the flappers are black and the other surfaces are colored in yellow at every 10 mm and red at every 100 mm from a reference position.
- Alarm switches and/or an analog output (4 to 20 mA DC) transmitter with a magnetostrictive sensor can be provided additionally onto this level indicator.
