Omron, BF-[](R) / BS-1(T)

The BF-1 is ideal for liquids with low specific resistance, such as wastewater.
The BF-[](R) is used when a strong mounting is required.
The BS-1 is used when high-temperature, high-pressure resistant is required.
The BS-1T is used when corrosion resistance is required.

Note:Two-wire Electrode Holders (R models) have a built-in resistance of 6.8 kΩ. They should be used with the Two-wire 61F Controllers.

Note:There must be a sufficient ambient temperature in a high-pressure environment to prevent vapor leakage. Use the Electrode Holder according to the following pressure-temperature curve.

* If it is not necessary to seal the tank inside and outside.
The Electrode can be secured with F03-17 Nuts. (Refer to Data Sheet.)

BS-1T

*1. All of the clamping section is made of fluororesin.
*2. If it is not necessary to seal the tank inside and outside.
The Electrode can be secured with F03-18 Nuts. (Refer to Data Sheet.)
*3. The material of the Connecting Nuts is the same as the material of the BS-1T. Connecting Nuts made of HAS B, HAS C, or titanium, however, do not have the screw or screw hole labeled 2-M4 in the figure.
*4. The section shown with dotted lines is sold separately.
