Electrode Holder BF- (R)/BS-1(T) CSM BF- (R) BS-1(T) DS E 7 1 Complete Lineup for Use in High- temperature, High-pressure Environments or Where Exposed to Chemicals 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. Refer to Safety Precautions for Electrodes and Electrode Holders.

Applications Liquids with low specific General applications for purified water Boiler water level Acid or alkaline resistance, such as and wastewater detection or high- solution level wastewater and cloudy temperature tanks detection water Note: 1. Two-wire Electrode Holders (R models) have a built-in resistance of 6.8 k. They should be used with the Two-wire 61F Controllers. 2. 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. 1BF- (R)/BS-1(T) Pressure-Temperature Curve Temperature (C) 200 150 100 Example For a pressure of 1.6 MPa, the temperature inside 000.4.8 1.2 1.6 2.0 2.4 the water tank must be at least 200C.
