∗1 Refer to the graph of measurable range for ethylene glycol aqueous solution on page 10. Measurement is possible as long as the fluid does not corrode the wetted parts and viscosity is 3 mPa・s (3 cP) or less. Be aware that water leakage may occur due to internal seal shrinkage or swelling depending on the type of fluid.
∗2 If 0.5 s is selected for the response time of the switch output, the repeatability will be ±3% F.S.
∗3 The operating pressure range and proof pressure may change according to the fluid temperature. Refer to the graphs on page 8.
∗4 Cleared when the power supply is turned off. The hold function can be selected. (Intervals of 2 or 5 minutes can be selected.)
If the 5-minute interval is selected, the life of the memory element (electronic parts) is limited to 1 million times. (If energized for 24 hours, life is calculated as 5 minutes x 1 million = 5 million minutes = about 9.5 years.) Therefore, if using the hold function, calculate the memory life for your operating conditions, and use within this life.
∗5 The response time when the set value is 90% in relation to the step input (The response time is 7 s when it is output by the temperature sensor.)
∗6 The response time until the set value reaches 90% in relation to the step input (The response time is 7 s when it is analog output by the temperature sensor.)
∗7 When the temperature sensor is used, it will be 250 VAC.
∗8 For details, refer to “Wetted Parts Construction” on page 10.
∗9 When the piping diameter or piping passage is restricted, the specifications may not be satisfied.
∗ Products with tiny scratches, marks, or display color or brightness variations which do not affect the performance of the product are verified as conforming products.
